epidermolythic acanthoma (if unique)

Agree with epidermolythic acanthoma

Epidermilytic acanthoma. Multiple genital ones have been described.

Yes, you right I meant that I did not think it was part of a genodermatosis. Agree multiple genital and even disseminted cases have been reported

Yes this is a rather wart-like example of epidermolytic acanthoma. To our knowledge it is not that rare on the genitalia but perhaps under-recognised and may be confused with viral warts although none of the reported cases that have been worked up has HPV genome been demonstrated. I don't think I have ever seen a white sponge naevus (genital, oral or otherwise) as a hot case but it should have typical clinical features and is usually present from early life.  Here the epidermolytic hyperkeratosis pattern is rather spectacular. There are now four genital cases of EA in my slide collection, all "routine" cases.
