angioleiomyoma

 [an″je-o-li″o-mi-o´mah]
a leiomyoma arising from vascular smooth muscle, usually a solitary, nodular, sometimes painful, tumor on the lower limb in middle-aged women; it is often more deeply situated than ordinary leiomyoma and is usually subcutaneous.

vas·cu·lar lei·o·my·o·ma

a markedly vascular leiomyoma, apparently arising from the smooth muscle of blood vessels.

angioleiomyoma

(1) A benign smooth muscle tumour that can occur any place in the body, arising in the tunica media of vessel walls as a nodular subcutaneous nodule; more common on the lower leg of middle-aged women.
(2) A skin lesion consisting of a solitary deeply eosinophilic well-circumscribed nodule in the deep dermis of acral skin which histologically consists of spindled cells.
