Subcutaneous intravascular pyogenic granuloma: a case report and review of the literature.

Pyogenic granuloma (PG), also known as lobular capillary hemangioma, is a common vascular proliferation that often occurs after minor injury or infection of the skin. Typically these lesions occur in the superficial dermis; although rare, subcutaneous and intravascular lesions can occur. We present a case of PG with the unusual features of being both a deep subcutaneous and intravascular lesion localized to the forehead without antecedent trauma. We also review the literature on PG and discuss the differential diagnosis.
