Intramuscular hemangioma of the hypothenar eminence. A case report

Intramuscular hemangiomas are benign vascular tumors. They develop in striated muscles. Various sites have been reported in the literature but only rarely in the hand. We report on a case of an intramuscular hemangioma located within the hypothenar eminence, diagnosed by a biopsy. Treatment options are limited in the hand as embolization may lead to a risk of digital ischemia and sclerotherapy may lead to recurrence. This type of infiltrating tumor is poorly structured within the muscle, thus simple removal is not an option. Surgical excision of the entire affected muscle, in our case the abductor digiti minimi, was performed without any consequences on the hand's function and no signs of recurrence at the latest follow-up of 6 months.
