SUMMARY A 58 year old man presented with what seemed to be a simple penile lesion, but which on subsequent histological examination proved to be a malignant melanoma. The lesion was excised by circumcision. No further treatment was considered to be necessary.
A female patient developed a severely irritating papulous dermatosis localized on the face and arms, running a chronic course. Histology displayed blister formation and mucin deposits in the corium. Laboratory determinations showed antibodies against thyroglobulin and cytoplasmic antibodies with high titers; thyroid function tests were normal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
