Abstract
- We experienced three cases of arteriovenous hemangioma in middle-aged patients. Each of them an asymptomatic small red to purple papule on the face and arm, which showed typical microscopic features of proliferating variously sized vessels in the dermis. An interesting finding was the increased number of mast cells identified in the stroma and perivascular channels, which may be associated with angiogenesis in inflammatory and neoplastic processes. Although arteriovenous hemangioma has been reported infrequently, its true incidence is considered to be higher than expected. Thus biopsy should be performed for exact diagnosis of small vascular lesions.
