Angioleiomyoma of Distal Ulnar Artery of the Hand

Abstract

Angioleiomyomas are rare and benign smooth muscle tumors that are infrequently found in the hand. We present a case of angioleiomyoma of the distal ulnar artery that presented with painless mass and gradual enlargement. 3D computed tomography angiography revealed a mass involved with ulnar artery. Surgical excision was performed, and the histology was characteristic of an angioleiomyoma. The patient became asymptomatic after the operation. At 1-year follow-up after the operation, no recurrence has developed. The purpose of this case report is, furthermore, to consider the differential diagnosis in painless masses of the hand.

A Rare Case of Angioleiomyoma of the Hand

“…Epidemiologically, females are affected more than males with a ratio of 1.7:1, but upper extremity involvement was reported to be more common in males, as in the case of our patient [3,4]. Multiple theories regarding the etiology of angioleiomyoma have been proposed in the literature, including minor trauma, hamartomatous changes, venous stasis and hormonal imbalance [1,3].…”

“…Angioleiomyoma is a rare tumor consisting approximately 4.4% of all benign soft tissue masses [1]. It originates from the smooth muscle cells in blood vessels and involves mostly lower extremities.…”

“…Pain is the most common presenting complaint, occurring in 60% of cases [1,3,4]. The pain is thought to be a result of stretching of the nerves in the capsule of tumor, vasoconstriction giving rise to local ischemia or due to release of chemical mediators from mast cells [3,4].…”

“…Angioleiomyoma, also known as "vascular leiomyoma," is a benign tumor derived from the muscular tissue in tunica media layer of the vascular system. Although it can arise anywhere in the body, finger involvement is a very rare entity [1,2]. It typically presents as a slowly growing subcutaneous mass with pain being the most common presenting symptom [1,3].…”

“…Although it can arise anywhere in the body, finger involvement is a very rare entity [1,2]. It typically presents as a slowly growing subcutaneous mass with pain being the most common presenting symptom [1,3]. The typical management involves surgical excision of the mass with close follow-up.…”
