Angioleiomyoma - A Case Report

Angioleiomyoma is a rare benign soft tissue tumour arising from smooth muscle, representing <1% of upper limb soft tissue tumours. We report a 54-year-old male presenting with a progressively enlarging atraumatic lesion along the palmar side of the base of the ring and little finger. A biopsy was done to determine the diagnosis. Intraoperatively, the lump was found to be intimately related to the radial digital artery, it could not be excised en-bloc without transecting the radial digital artery of the little finger. Following excision, the ends of the digital artery were anastomosed. At 10-months follow-up, the hand was fully functional without any evidence of cold-intolerance or neurological deficit along the distribution of the digital nerve. We review the literature on angioleiomyoma and report careful resection of the tumour with digital artery transection and repair as a treatment option for angioleiomyoma of the digital artery.
