Synovial Sarcoma: Malignant Soft Tissue Sarcoma With Benign Clinical Characteristics—A Case Report

Abstract

Synovial sarcomas are rare malignant soft tissue tumors with significant metastatic potential. Although they can occur in various parts of the body, they are most commonly found on the extremities. These tumors typically develop in children and young adults, making occurrences in individuals over 50 years of age unusual. Due to their slow-growing and nonpainful nature, synovial sarcomas can often be mistaken for benign pathologies. The standard treatment involves complete surgical excision with negative margins, which offers a favorable 5-year prognosis. This case highlights the importance of early recognition and intervention in managing soft tissue sarcomas. In this case report, we present a 57-year-old African male with a 2-year history of gradual, nonpainful swelling on his left hand, diagnosed as synovial sarcoma. The patient was successfully treated with complete surgical excision.
