Rare Case of a Very Large Angioleiomyoma of the Dorsum Foot

摘要

Angioleiomyomas are relatively rare benign smooth muscle soft tissue tumors which often occur on the extremities. They are rarely diagnosed preoperatively as clinical and radiological examination is often nonspecific and inconclusive. An 80-year-old male presented with a 10-year history of a progressively growing and symptomatic lesion on his right dorsal foot within the first intermetatarsal space. The preoperative diagnosis was suspected to be a neurogenic schwannoma arising from the deep peroneal nerve. Simple excision and histopathology confirmed a diagnosis of angioleiomyoma with nil recurrence or complications. The size of the angioleiomyoma was the second largest reported in literature to date. Angioleiomyomas are often misdiagnosed, and a degree of suspicion should be maintained in patients presenting with lower extremity growing soft tissue tumors.
