Angioleiomyoma

Angioleiomyoma (vascular leiomyoma, angiomyoma) of the skin is thought to arise from vascular smooth muscle, and is generally acquired. Angioleiomyomas appear as small (<2 cm), firm, movable, slow growing subcutaneous nodules. Pain is a common symptom. They are most commonly seen on the extremities. The cause of angioleiomyoma is unknown.

== Signs and symptoms == Angioleiomyomas present as solitary, small, slow-growing, firm, movable, subcutaneous nodules that typically measure less than 2 cm in size. Pain is the most obvious symptom of angioleiomyomas. Wind and cold exposure can set off paroxysmal episodes of pain. It is believed to be caused by smooth muscle contractions that are active and cause localized ischemia. It seems that rest is a relieving aspect. Although this tumor can develop anywhere in the body, it usually first appears in the extremities, then the head and trunk. The lesion is usually located in the subcutis, however it can also appear in the dermis.
