Angioleiomyoma in a 52-year-old female wrist: A case report

Abstract

Angioleiomyoma is a benign soft tissue tumor arising from vascular smooth muscle and most commonly presents in the lower extremities. We report a case of a 52-year-old right-hand dominant woman who presented with a 2-year history of intermittent, nonradiating left wrist pain, which she described as achy in nature without numbness or tingling. A focused physical examination revealed no edema, no obvious skin changes; there was tenderness over the volar-radial aspect of the left wrist, with an underlying firm, mobile, and palpable soft tissue mass. There was no prior history of trauma or surgery to the affected area. Ultrasound (US) examination demonstrated a 0.6 × 0.6 × 0.4 cm well-defined, oval, hypoechoic soft tissue mass within the volar radial soft tissues of the left wrist. The lesion abutted the radial artery without signs of calcification or necrosis. Color Doppler showed little to no vascularity within the mass nor radial artery thrombosis. Histological analysis revealed an angioleiomyoma arising from the radial artery wall. A case presentation like this would most commonly be due to a volar ganglion cyst; however, it is important to consider other soft tissue masses in differential diagnosis, such as angioleiomyoma, as treatment varies significantly.
