Recurrent cutaneous leiomyosarcoma

Cutaneous leiomyosarcoma is a rare tumour, accounting for 2.3% to 6.5% of all soft tissue sarcomas. The case of a young patient with a cutaneous leiomyosarcoma on the right gluteal region is here presented. The lesion misdiagnosed as a keloid after primary excision of histiocytoma had a two-year history, had been excised twice. The tumour was widely excised, and the wound closed primarily. No recurrence or distant metastasis are reported 26 months after the initial presentation. Clinical, histological, immunohistochemical features and surgical strategies of the reported case are discussed and compared with literature.
