Talk:Tinea versicolor

Unreliable source for derogatory slang

Hello, I just thought it might be good to include in the article that the moniker "Haole rot" is considered by many to be deragatory, It would be good to include that bit so that those unaware won't offend people by saying it. Hfwd 05:01, 14 Jun 2005 (UTC)

Still no verifiable reference. While I admit that a number of severe presentations of fungal skin infections, to the point of open raw lesions, are often referred to as "rot" with casually applied, but not specifically, modifying labels. Jungle rot is probably the one best known in the States.

If it is necessary for such a topic to exist, it might be interesting to have a daughter article referring to the various damaging social aspects of various dermal fungal infections, including derogatory terminology, rather than dumping unverifiable terms sprinkled here and there.

Peter Elam's disease is not verifiable, never mind totally impossible

Previously, this article mentions that tinea versicolor is also known as Peter Elam's disease, because a traveler named Peter Elam supposedly swam in the Amazon river and got infected with the yeast. I could not find a reference outside of Wikipedia on this, and therefore deleted it.Hfwd 05:01, 14 Jun 2005 (UTC)

Here it is, more than two years along and this "Peter Elam" fictional bit of nonsense appears again. One "reference" at man-matters is only a copy of this wiki article downloaded at some point previous to June 14, 2005. This is one of the most alarming aspects of Wiki -- that when someone reprints blatently false, misleading, and definitely not up to encyclopedian standards, that no one else is ever expected or required to check back in the future to see if anything has "changed" (tho that again could easily be the moment that it is still (or again) not anything worthy of being taken authoritatively.

The other "reference, that purported to be a professional sounding "organization", but a whois search reveals only the following.

So I would suggest that "SkinCareNet.org" may not be a sterling source of anything. Any "illness" caused by a universally normal resident of the human epidermis can scarcely be claimed to have been "caught" by any one who one day swam in a river that had been used by possibly hundreds of thousands of humans prior to his solitary swim and who then was solitarily and exclusively responsible for its rapid spread through-out the entirety of humanity. :o)

UK Institue of Dermatology Treatment Protocol

Past telephone advice received from the St John's Institute of Dermatology (at St Thomas' Hospital) allowed me to construct a treatment protocol sheet. However given both that this is my construct and not endorsed by them, and the general policy of authors not referring to their own works in wikipedia, I am reticent about adding an external link to the guideline which is on my own website: http://www.Medik.Info/MI_Derm_PityriasisVesicolor.doc . So I seek the advice of other editors who may wish to add the link. David Ruben ^Talk 01:05, 28 May 2006 (UTC)

Pityriasis Versicolor versus Tinea Versicolor

I think that a mention to the below controversy about the difference between tinea and pityriasis versicolor should be mentioned within this article, even if many people believe that there is no difference. I got from a lecture today that there is in fact a difference in that tinea is more of a ring-worm-like versicolor. It should be noted somewhere in this entry. IsaacD (talk) 14:23, 7 August 2013 (UTC)

The following discussion is an archived debate of the proposal. Please do not modify it. Subsequent comments should be made in a new section on the talk page. No further edits should be made to this section.

Suggestion to move to Pityriasis vesicolor

ICD9 clearly indicates that official international term is Pityriasis versicolor with alternative terms being "Infection by Malassezia [Pityrosporum] furfur, Tinea flava, Tinea versicolor"[1]. Should not the article be moved (drug names are as per WHO's INN) ? My nerve left me as I was about to BE BOLD, as I can appreciate Tinea versicolor as having some following. David Ruben ^Talk 01:20, 28 September 2006 (UTC)

I disagree with a move. It may be the "official" International term, but that term is very little recognized in the English Speaking countries (this IS En.Wiki). Additionally, a vast number of references in the lay press, in all types of medical-nursing tomes, and the labeling and advertising of hundreds of products all refer to Tinea Versicolor. Better, I think, to have Pityriasis forward directly to this topic (a statement at the top of this topic page will indicate that a forwarding has occurred). This will help anyone who actually shows up and types the other term into the search box. -I am Kiwi 02:26, 28 September 2006 (UTC)

Comment - "nursing tomes, and the labeling and advertising of hundreds of products" is not the most reliable method of ensuring articles are correctly named (wikipedia has Acne vulgaris rather than acne, "spots" or "zits" - all of which are more frequently used in advertising products). In my 13years experience in UK General Practice, UK Dermatologists & GPs overwhelmingly use "pityriasis versicolor", and with most GP surgeries now going to paperless notes, the main computer systems all recognise "pityriasis versicolor" as the primary term (I'll try tomorrow to see if the most widely used system recognises at all Tinea versicolor as a synonym).

• See British Association of Dermatologists' Patient Information and Leaflets: Pityriasis versicolor](PDF)
• The American Academy of Dermatology in its A-Z listing of conditions has under "P" "Pityriasis versicolor : Pityriasis (tinea) versicolor is a...", so it is "recognized in the English Speaking countries".

As for wider usage, there is not a "vast" difference between the terms: PubMed and (Google) searches gave: Tinea versicolor=780 PubMed (196,000 Google) vs Pityriasis versicolor 465 (143,000).

I wonder if anyone knows the background to these 2 terms - where and when did each term originate, is there a US / UK difference in usage, or is it a more general English / rest of world difference ? David Ruben ^Talk 04:16, 29 September 2006 (UTC)

• """THUMBS DOWN"""
• Recommend for Redirection

Go to the grocery store or drugstore and read the labels of products that cure or treat the condition and you will find tinea. Indeed, the tinea portion of the name is used for all the the common fungal infections of the human skin. Including fungal infections of the scalp (dandruff is the symptom of this infection with pyrithione zinc -in Head & Shoulders- & selenium chloride -in Seldane- recommended for treatment. These two chemical forumulations work because they are anti-fungals, and they also work on jock itch and the so-called ring worm. Seldane is prescribed by dermatolists to treat all types of tinea fungal infections.

The Merck Manual for patients uses the term. Articles in the lay press use it, not Pityriasis. As has been mentioned elsewhere on this website, Wikipedia is not a professional resource for professional specialists, but for the lay public needs. As I said, what is appropriate is for the "proper medically recognized name" to have its own page that will forward to this topic page. A nav box would best be served by having all the Tineas included, along with Dermatology, fungus infections and various other applicable linking topics.

It is appropriate and sufficient to, in the intro paragraph at the top of the page, to have a referenced explanation that the term is the correct medical terminology. It should include a definition of the word Pityriais. This will serve the purpose of educating people. Perhaps in fifty years, the grocery store shelves will be stocked with products labeled with the term, but I think Tinea will be with us for a long, long time. -I am Kiwi 05:35, 29 September 2006 (UTC)

Agree wikipedia generally goes for the commonly used term, but not always on medical topics (Heart attack redirects to Myocardial infarction). Yes EMIS (probably UK's most widely used GP computer notes system) takes Tinea versicolor as a synonym. As for the UK's "lay public needs", look at the British Broadcasting Corporation (BBC) public information service for health topics http://www.bbc.co.uk/health/conditions/ - tinea is not mentioned at all (which I admit surprised me). You are arguing over what promotional material (adverts and over-the-counter products) are available to you locally. Whilst I don't dispute the term you therefore may most commonly see, wikipedia has global reach, I think I've provided a broad enough range of sources to suggest that, at least in the UK, most doctors will use P.V., patients will be so advised, if they look it up at specialist UK website the term will be used and if they look on one of the UK's most used open websites the same will apply. Clearly your experience in US is for the other T.V. term. What would be nice is if other editors could now comment on what the situation is elsewehere (e.g. Canada, Ireland, South Africa, Australia, New Zealand, India etc).

Rebuttal

Below, I will attemp to present consecutive sets of contrasting points, first of Pityriasis, then of Tinea.

First of all, the Wiki disambiguation page for the word Pityriasis - Pityriasis The list includes

• fungal conditions
• auto-immune conditions
• unknown-origin conditions ...
• and a BIRD - Pityriasis gymnocephala

Pityriasis - 34,100 mentions in various online dictionaries - definition -

• Any of a number of VARIOUS skin diseases of humans AND ANIMALS,
• characterized by epidermal shedding of flaky scales.
• a descriptive SYMPTOM, not a causation
• From the Greek, meaning "dandruff" - only one result from Bartleby.com

Tinea - 73,100 entries solely in online dictionaries Its meaning, CONSISTENTLY throughout, is A FUNGAL INFECTION OF THE SKIN. - and 11 returns from Bartleby.com

Tinea, therefore, specifically refers to FUNGAL INFECTIONS OF THE SKIN and nothing else. That is its definition.

The various kinds of medical conditions associated with Pityriasis are these -

• Pityriasis alba (also called 1) pityriasis streptogenes, 2) pityriasis simplex & 3) erythema streptogenes)
• Pityriasis lichenoides chronica
• Pityriasis lichenoides et varioliformis acuta
• Pityriasis rosea
• Pityriasis rubra pilaris
• Pityriasis versicolor -

For Tinea (fungal infections of the skin) --

These fungi attack various parts of the body and lead to the following conditions:

• Tinea corporis affects the arms, legs, and trunk
• Tinea capitis affects the scalp
• Tinea cruris (jock itch) affects the groin area
• Tinea pedis (athlete's foot) affects the feet
• Tinea unguium affects the fingernails and toenails
• Tinea versicolor - affects upper body, chest, arms, back, stomach, neck and face
• Tinea manuum affects the hands and palm area

BUT, Pityriasis means flaky & scaly - And the spots MAY be flaky and scaly, but NOT ALWAYS.

What IS distinctive of this specific fungal infection is the versicolor condition, where in the winter months, when most people aren't in the sun, tinea versicolor most often appears on the skin as pink to brown spots. During summer, those same pink spots turn to white spots when the surrounding skin tends to tan or generally darken. Exposure to heat hot baths, shower and after exercise causes the spots to be dramatically white spots against the surrounding flushed skin.

This UK Dematology website, [2]

owned by Meddaid Ltd (and adhering to the Code of Practice of the British Pharmaceutical Association) gives a page to Tinea "Tinea is a type of fungal infection with one of a few types of fungus. Tinea infection can occur in many sites of the body such as the foot, groin and nails." [3] [4]

This same website does not feature the word Pityriasis for any dermatological conditon. (use search or click on "P" on above page). It can be found associated with non-derma conditions.

Tinea versicolor - from eMedicine at WebMD - Which is a doctor-training site, certified by Medical Licensing Boards to give CME Credits for various specialities -

[5]

• There is a long list of authors and editors who collaborated on this article -- And it can be noted from the 9 bibliography entries that there is absolutely no agreement regarding any so-called official name. Tinea and Pityriasis are used equally freely, both two decades ago, and in this present day.

Examining all this (plus the journal and textbook links on Google Scholar) There has seemingly been no obvious trend towards one or another.

Search eMedicine.com professional journal article & CME database for Pityriasis, and you pull up these [6]

Then see the same eMedicine.com entry for ALL FUNGAL INFECTIONS of the dermis and note the conditions listed.[7]

Then, on BBC Online, under "Ask the Doctor" and under "Health Conditions", written by different Dermatologists, it says this - "The proper medical name for these (fungal) infections is Tinea, and this is often followed by the Latin name for the affected part of the body. For example, Tinea pedis affects the feet (also called athlete's foot), Tinea corporis affects the body and Tinea capitis affects the scalp."

another UK site -

[8] - Reviewed by John Pillinger, GP - What is pityriasis versicolor? --

"This (Pityriasis veriscolor) is a common skin disease caused by an overgrowth of the yeast fungus called Pityrosporum orbiculare (yeast also known as Malassezia furfur).

Most adults have Pityrosporum orbiculare on their skin; however, in a few people its presence results in a harmless skin disease.

Pityrosporum orbiculare also plays a role in the development of cradle cap (also known as seborrhoeic dermatitis). (end quoted section)

May I suggest that in THIS PARTICULAR fungal infection of the integument, that often associated with Pityriasis name possibly came to be more used because of the particular fungus involved - Pityrosporum, in addition to the fact that the lesions can be flaky and scaly. The two had a marked similarity at first glance, even though one was a description of how a lesion looks and the other a particular yeast organism.

What can be seen is that Tinea means "fungal infections" and there is a CONSISTENCY across the board with each and every other symptomatic fungal condition of the human integument.

Integument - Covering of the body, which protects it from the outside world and from drying out. In humans and other mammals it consists of the skin (including outer epidermis and inner dermis) and its related structures, including hair, nails, and sebaceous and sweat glands.

Why not 1% selenium sulfide solution?

Wouldn't a 1% solution cure tinea versicolor too, albeit slower than the 2.5% solution? 71.123.95.142 (talk) 22:02, 22 April 2008 (UTC) John S.

Apparently, yes. One of the article's reference sources state: "Nonprescription treatments include 1 percent selenium sulfide (Selsun) shampoo applied to the skin from neck to waist for 30 minutes daily for a week (I'd also shampoo the scalp the first few days) and clotrimazole (Lotrimin) cream twice a day for 3 weeks, or Lamisil cream once a day for a week. Prescription treatments include ketoconazole 2 percent shampoo applied to damp skin in a thin layer and left on for five minutes for three straight days, or Selsun 2.5 percent lotion applied daily for 1 week — allow to dry for 10 minutes before showering. Alternatively, leave Selsun on your body for 12 to 24 hours, rinse it off, and repeat weekly for four weeks." (Joseph A. Spadaro (talk) 06:44, 5 July 2008 (UTC))

Mycology

In Weedon's Skin Pathology there is some discussion about the state of flux of taxonomy in this area. It says Malassezia furfur is the former name of a fungus known for decades as Pityrosporum ovale (in its ovoid form) and Pityrosporum orbiculare (in its spherical form), that was renamed following a taxonomic review of the Malassezia species in 1996. Four new species were described and the upshot of this was that M. globosa is the name of the organism that both colonises healthy skin and causes pityriasis/tinea versicolor (whatever you want to call it). Whilst I recognise Dr Weedon as a world authority in Dermatopathology, I recognise this edition of his text is now dated, and so, although I'd like to, I'm hesitant to include this information in the article because it may not respresent current understanding in mycologic taxonomy. Is anybody else aware of more recent developments in this area? Mattopaedia (talk) 00:46, 11 December 2008 (UTC)

Here is a couple recent articles

2 TI Malassezia species isolated from lesional and non-lesional skin in patients with pityriasis versicolor.

AU Prohic A; Ozegovic L

SO Mycoses. 2007 Jan;50(1):58-63.

Pityriasis versicolor (PV) is a superficial fungal infection where Malassezia species play a definite causative role, but the clinical significance of each of these species is not fully understood. The aim of our study was to analyse the prevalence of Malassezia species in PV lesions and to examine if the range of species varies with patient sex, age, direct microscopy findings and some clinical data. Ninety patients with PV completed the study. The samples were obtained by scraping the skin surface, both from lesional and non-lesional skin and then incubated on Sabouraud dextrose agar and modified Dixon agar. The yeast isolated were identified according to their macroscopic and microscoipic features and physiological characteristics. In PV lesions, the most common species was M. globosa (63%), followed by M. sympodialis (14%), M. furfur (10%), M. obtusa (8%) and M. slooffiae (4%). The most frequently isolated species from clinically healthy skin were M. globosa (49%), M. sympodialis (37%) and M. furfur (5%). We found significant difference in the distribution of Malassezia species between lesional and non-lesional skin and in the distribution of Malassezia species according to the direct microscopy findings. M. globosa in its mycelial phase is the predominant species involved in the aetiology of PV.

• Let me add a quote from Andrews' Diseases of the Skin: Clinical Dermatology, a very reliable secondary source from 2005: "Tinea versicolor is caused by Malassezia furfur. The yeast phase of this organism is classified as Pityrosprum orbiculare. As a yeast, this organism is part of the normal follicular flora. It produces skin lesions when it grows in the hyphal phase." From: James, William; Berger, Timothy; Elston, Dirk (2005). Andrews' Diseases of the Skin: Clinical Dermatology. (10th ed.). Saunders. Page 313. ISBN 0721629210.

• However, in 2003, Fitzpatrick's, 6th Ed., ISBN 0071380671, an excellent secondary source, gave a full discussion on this very topic. Here are some quotes (and Fitzpatrick's does use in-text citations to reference primary sources throughout these quotes, but I will not include those here):

"The genus Malassezia includes seven species of lipophilic basidiomycetous yeasts: Malassezia furfur, M. pachydermatis, M. sympodialis, M. globosa, M. restricta, M. slooffiae, and M. obtusa. Previously, M. furfur, M. pachydermatis, and M. sympodialis were the only members of the genus. In 1996, Gueho et al. proposed a new taxonomic classification based on morphology, ultrastructure, and molecular biology that added four new species. These yeast cause a wide spectrum of superficial cutaneous disease, including tinea versicolor, folliculitis, and seborrheic dermatitis.

Eichsstedt first recognized tinea versicolor as a cutaneous fungal infection in 1846. For several years the disease was considered to be dermatophyte in origin, but Baillon, impressed by the yeastlike nature of the organism, coined the term Malassezia in 1889 to distinguish this organism frin the Microsprum species of dermatophytes. In 1951, Gordon isolated and characterized the organism M. furfur and renamed it Pityrosporum orbiculare. It is now recognized and accepted that M. furfur is the correct name and that P. orbiculare, P. ovale, and M. ovalis are synonyms." Page 2014

"Superificial fungal infections are also more common in atopic individuals and may contribute to the exacerbation of atopic dermatitis. Patients with atopic dermatitis have an increased prevalence of Trichophyton rubrum infections compared to nonatopic controls. There has been particular interest in the role of Malassezia furfur (Pityrosporum ovale and P. orbiculare) in atopic dermatitis. M. Furfur is a lipophilic yeast commonly present in the seborrheic areas of the skin." Page 1187

• There is also an updated Fitzpatrick's from 2007, which I do not own, but which may have even more recent information on the topic. The 2007 updated edition's information is as follows: Wolff, Klaus; Goldsmith, Lowell; Katz. Stephen; Gilchrest, Barbara; Paller, Amy; Leffell, David (2007). Fitzpatrick's Dermatology in General Medicine. (7th ed.). McGraw-Hill Professional. ISBN 0071466908.

• I will only provide quotes from excellent secondary sources, leaving you to draw statements and conclusions from them for the wikipedia article. I hope this helps, and I apologize for any typos. Additional secondary sources may be found through WP:DERM. Please let me know if you need any other help. Thanks! kilbad (talk) 16:35, 11 December 2008 (UTC)

Thanks guys! Its interesting to see that even the experts can't sem to agree on taxonomy. I was under the impression that M. furfur was reclassified into 4 new species & so ceased to exist -- apparently not...

I think for the purposes of the article it would be fair to say that M. globosa is the causative agent for the majority of PV. Cheers! Mattopaedia (talk) 01:10, 12 December 2008 (UTC)

Keep in mind too that clinical medicine usually lags behind advances in most areas of basic science, and microbiology is no exception. Eg, although it was renamed Chlamydophila a while ago, nearly all call it Chlamydia. Same goes for Pnemocystis carinii vs. Pneumocystis jirovecii. So I wouldn't be surprised if most basic scientists agree with the renaming of M. furfur and yet it hasn't made its way into the clinical texts yet. It's just the nature of the beast. --David Iberri (talk) 02:01, 12 December 2008 (UTC)

Possibly opening a 'can of worms', but I initially hoped to bring a little more uniformity to two related articles Dermatophytosis and this on PV. via a post the Derma Talk page. However, looking at this a little more deeply and without and expert knowledge of this topic I found a more recent study from South America (Petry V, et al, 2011 Aug, Identification of Malassezia yeast species isolated from patients with pityriasis versicolor. An Bras Dermatol. 2011 Aug;86(4):803-6) Suggest M. sympodialis as a more prevalent agent. I suspect (although I can't find any study), that there'll be a geographical and possibly other epidemiological factors, such as diet - some spp. appear to be more lipophilic than others, that play a role in which agent is the most prevalent in particular communities. I'd like to link into the PV article and get the main author of this article to re-evaluate the opening text and revise with a more cautious reference to these articles. Then maybe agree to have the Dermatophytosis and PV article make a more general ref to Malassezia and various spp. As ref to one sp. as more prevalent than any other appears to be unreliable at present. Is there any owning editor that can comment on this? Regards, Dave Morgan, DO — Preceding unsigned comment added by 91.125.90.45 (talk) 09:05, 3 April 2012 (UTC)

clotrimazole

The article says "Other topical antifungal agents such as clotrimazole, miconazole or terbinafine are less widely recommended.". Why? Is there a source for this?

Tinea refers to fungal only and not to yeast.

The article title should be changed to Pityriasis versicolor. Tinea is a term reserved only as a pronoun for any fungal disease of the skin as defined by Mirriam Webster. . Tinea versicolor is a misnomer as the causative organism is a yeast as clearly documented by the post here in this discussion section by kilbad in 2008. The word Tinea versicolor should be a redirect to this article which should be retitled Pityriasis versicolor.Leo2618 (talk) 22:02, 6 July 2011 (UTC)

Itching; Selenium sulfide; etc. - personal observations to help others

I can't offer a citation for the listed symptom of Severe Pin-Prick Itching, but my personal experience confirms both the maddening symptom, and its apparent contributing factor(s).

Another contributing factor is my allergy to wheat, and milder allergy to corn, slight allergy to rye and barley - the dermatological reactions to them exacerbate the versicolor, evidently because they body is already in an inflammatory state.

Re: Selsun Blue with selenium sulfide, leaving it on for 30 min can cause skin damage (a reddened and darkened thickening with a leathery feel, that is painful to the touch, and then peels like an orange to leave a reddened, very tender and painful patch) in people with fair or delicate skin. Do *not* jump immediately into leaving it on for 30 minutes. For people with fair/sensitive skin, start with 5 min and, if that's tolerated, go to ten min., and so on, to establish the *individual tolerance*.

I've found that a warm (NOT hot!) bath of 1 cup epsom salts per 10 gal of water, with a squirt of completely neutral (hypoallergenic, no fragrance, no colorants, etc.) liquid "soap" or even mild "free of everything" detergent, works well to ease the itching and assist in control. Adding some Baking Soda helps in the hotter weather, in conjunction with using the Selsun Blue as a "body wash" - i.e., apply and to whole body when wet, then rinse after 5-10 min.
