Skin ulcerations as manifestation of vasculopathy in neurofibromatosis.

Vascular involvement in neurofibromatosis sometimes occurs and usually affects larger blood vessels of internal organs. We describe an unusual case of a now 41-year-old man with extensive skin involvement with ulcerations and histopathologic features of fibromuscular dysplasia, which has not been previously reported in the skin.

Carcinoma and eccrine syringofibroadenoma: a report of five cases.

Results: We have studied five cases with a histological mixture of ESFA and carcinoma. The carcinoma had a partial squamous cell cytology in all cases.
