Angioendothelioma: report of an unusual case in an American black.

Angioendothelioma is a rare malignant vascular tumor occurring on the face or scalp in an elderly individual or in an area of antecedent radiotherapy or chronic lymphedema. We are reporting the second fully documented case of angioendothelioma occurring in a black patient. The case is also of interest because initially the tumor mimicked kerion, both clinically and histopathologically.
