Talk:Erythroplasia of Queyrat

Comment

I was under the impression (possibly mistaken) that EoQ and Bowen's disease of the penis were the same thing; is it only the etiology (HPV) that makes them different? Fuzbaby (talk) 14:32, 17 June 2009 (UTC)

Erythroplasia of Queyrat is a squamous cell carcinoma in situ of the glans penis. Bowen's disease is a more general term to denote a squamous cell carcinoma in situ. ---kilbad (talk) 17:32, 17 June 2009 (UTC)

Copied over: I think it is a good idea to move this stub article entirely to wider topic erythroplasia. 188.30.205.179 (talk) 18:22, 13 July 2014 (UTC)

It isn't a true erythroplasia though is it? -- CFCF 🍌 (email) 08:28, 14 July 2014 (UTC)

I saw you had begun a merge, and I'm not sure the resulting text is entirely correct. Axl? -- CFCF 🍌 (email) 08:31, 14 July 2014 (UTC)

Also, while this image is of a neoplasia, could it be used to show erythroplasia/erythroplakia as well? File:ZungenCa2a.jpg -- -- CFCF 🍌 (email) 08:37, 14 July 2014 (UTC)

Erythroplaisa = erythroplakia (French or Greek derivations I think, but I am 95% sure they are the synonyms in English dermatology)

Furthermore, According to some sources, "erythroplasia of Queyrat" also occurs in mouth, larynx, anus.

Imo, might be better to discuss all erythroplasias/erythroplakias on one page. 94.72.198.147 (talk) 12:14, 14 July 2014 (UTC)

And in answer to your Q about whether ZungenCa2a.jpg could be described as erythroplakia/erythroplasia, the answer is no if you are using the mainstream WHO definition (red patch which is a diagnosis of exclusion, but the red patch may show dysplasia or even be carcinoma in situ). Just to look at it, I would guess that the SCC has almost certainly invaded beyond the basement membrane since there is a tumor mass, and therefore the term carcinoma in situ is no longer appropriate. 188.30.200.29 (talk) 17:50, 14 July 2014 (UTC)

(I'm not sure why CFCF pinged me.) "Erythroplasia of Queyrat" seems to have more than one definition. In its most generic meaning, it could indeed be considered the same as (unqualified) "erythroplakia". However EoQ more commonly refers specifically to erythroplakia on the glans.

I agree that it would be sensible to merge the content into the article "Erythroplakia".

Regarding ZungenCa2a.jpg, I agree with 188.30.200.29. The tumour is invasive and has progressed beyond erythroplakia. Axl ¤ [Talk] 18:41, 14 July 2014 (UTC)

CFCF-- to clarify, I had not begn merge. I was expanding erythroplakia first then discovered EoQ article and added some of the content there too. Axl-- agree that EoQ seems to most commonly refers to the lesion on the glans, however unable to find a source which explicitly states this. Weird literature on this topic. Even though erythroplasia is much more common on the glans than anywhere else, most sources do not use the term in relation to the glans. E.g. the first page of google book results: [1]. Strange no? 92.41.94.235 (talk) 19:12, 14 July 2014 (UTC)

I don't appreciate you tagging my comment with "citation needed". By all means make own your reply, but do not edit my statements. Axl ¤ [Talk] 19:44, 14 July 2014 (UTC)

I try to emphasize that a source for such a statement is required, although from the sources I have read I tend to agree, that EoQ mainly refers to a red lesion on the glans/vulva which is caused by atrophic mucosa and containing carcinoma in situ. 94.196.239.62 (talk) 21:37, 14 July 2014 (UTC)

I searched for PubMed-indexed papers that have "Queyrat" in the title. Here are the papers since 2000 with identifiable definitions.

Specific to the penis:-

1. Ozturk
2. Schmitz
3. Fanning
4. Feldmeyer
5. Nasca
6. Micali same authors as 5: Nasca
7. Del Losada
8. Lee
9. Kaspari
10. Davis-Daneshfar

General epithelia (possibly):-

1. Fai
2. Choi "mainly occurs on the glans penis"
3. Zolis vulva
4. Wieland "mainly occurs on the glans penis, the prepuce, or the urethral meatus of elderly males"

Axl ¤ [Talk] 20:34, 14 July 2014 (UTC)

Can we use case reports? Or are you trying to demonstrate that the term EoQ is mainly used to describe a lesion on the glans? 94.196.232.85 (talk) 22:34, 14 July 2014 (UTC)

These papers demonstrate that the term is used mainly to describe disease on the penis. I am certainly not implying that these are WP:MEDRS-complaint sources. Axl ¤ [Talk] 07:57, 15 July 2014 (UTC)

• According to *Tobias Jeffrey S., Hochhauser, Daniel, Cancer and its Management, 2010 (6th edn), ISBN 1118713257, 9781118713259, p. 395, EoQ is now known as genital carcinoma in situ. See also p. 352 (where the revised edition doesn't seem to have caught the name change) on the penis. I'll copy this to the EoQ talk page at this point. Later additions should be copied there too.
