Synovial sarcoma is a malignant neoplasm that can affect patients of any age and any anatomical region. It is caused by the translocation of the SS18 gene on chromosome 18 with the SSX gene on chromosome X. The biphasic subtype is characterized by variable areas of spindle cells and glandularlike epithelium. The common clinical presentation of synovial sarcoma is a slow-growing, painless mass that generates a false impression of benignity. Also, the symptoms can be confused with other inflammatory conditions, or even go unnoticed for a long period. The present case report showed a 33-year-old male patient who presented a soft tissue tumor in the right ankle, close to the anterior tibial nerve. The diagnosis of biphasic synovial sarcoma was made after immunohistochemical analysis.
