Abstract

Superficial leiomyosarcomas are rare malignant smooth-muscle tumors accounting for 4-6.5% of all soft-tissue sarcomas, less than 2-3% of cutaneous soft-tissue neoplasms and 0.04% of all cancers. They are divided into cutaneous or dermal and subcutaneous leiomyosarcomas. Subcutaneous tumors have been reported to be associated with an increased risk of local recurrences and distant metastases, compared to their cutaneous counterparts. In this study, we describe a rare case of a recurrent subcutaneous trunk leiomyosarcoma in a 68-year-old male patient. Local recurrence developed two years after the complete surgical resection with wide margins and adjuvant postoperative radiotherapy. The management of the patient is discussed along with a review of the literature. We conclude that subcutaneous leiomyosarcoma is a rare clinical entity which may be associated with an atypical clinical presentation. Physicians should be aware of the misleading features of this tumor in order to avoid delay in diagnosis and treatment. Early complete surgical resection with wide margins of at least 2 cm is the cornerstone of treatment and has been reported to mostly influence the prognosis. However, the tumor has a high tendency to recur locally and metastasize. Recurrence may develop despite wide resection and radiotherapy. Long-term follow-up is mandatory.
