[Epithelioid hemangioma of the foot].
Epithelioid hemangioma (angiolymphoid hyperplasia with eosinophilia, EH/ALHE) is a rare benign angioproliferative lesion which typically occurs in the region of the head and neck. In the literature, occurence on the extremity is only rarely described. A case of multiple occurence of EH/ALHE in the skin of the toes and metatarsal bone with osteolysis is reported. Occurence on the extremity, superficial and deep affection and some "atypical" microscopic features may cause diagnostic dilemma. The key diagnostic features of EH/ALHE are vascular channels lined with epithelioid endothelial cells, surrounding layer of myopericytes, absence of atypia and mitotic activity and characteristic inflammation. Immunohistochemistry may be helpful in settling the diagnosis.
