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.
