Synovial sarcoma is a malignant mesenchymal neoplasm. Its typical presentation is a juxtaarticular mass, palpable and painless. We present a 63 years old male, with a tumor in the left inguinal region, an excisional biopsy was performed, resulting in a hydradenocarcinoma with a positive regional ganglion. Immunohistochemistry was performed resulting in poorly differentiated synovial sarcoma. Synovial sarcoma is a rare soft tissue neoplasm affecting young adults. It is located more frequently in the extremities and the presence of metastasis at diagnosis is common. It has a poor prognosis and the treatment is with surgical resection and chemotherapy.
