Abstract

Angioleiomyomas are rare, benign, smooth muscle tumors that occur predominantly in the lower limbs and infrequently in the upper limbs. We present a case of angioleiomyoma arising from the distal ulnar artery, presenting as a painful lesion with a 20-year history of diagnostic uncertainty. It was preoperatively misdiagnosed as an ulnar artery aneurysm. Surgical excision with primary end-to-end arterial repair was performed. Histopathological examination confirmed features consistent with a leiomyoma arising from the distal ulnar artery wall. The patient became asymptomatic following the surgery and remains pain-free at 6 months of follow-up.

Keywords

Resumo

Os angioleiomiomas são tumores benignos raros que se originam do músculo liso. Acometem predominantemente os membros inferiores e, mais raramente, os superiores. Relatamos o caso de um angioleiomioma originado na artéria ulnar distal, manifestando-se como uma lesão dolorosa com histórico de 20 anos de incerteza diagnóstica. Inicialmente, a lesão foi erroneamente diagnosticada como um aneurisma da artéria ulnar. O tratamento consistiu em excisão cirúrgica, seguida de reparo primário término-terminal da artéria. O exame histopatológico confirmou características compatíveis com leiomioma originado na parede da artéria ulnar distal. Após a cirurgia, o paciente evoluiu sem sintomas e permanece sem dor após 6 meses de acompanhamento.

Palavras-chave
