title: Synovial sarcoma of the foot mimicking acute gouty arthritis.
abstract: Synovial sarcoma is a slow-growing soft tissue sarcoma that mainly affects young adults. Patients commonly present with a slowly enlarging mass in the paraarticular regions of extremities. We describe a case of synovial sarcoma with an unusually acute presentation near the first metatarsophalangeal joint that resembled acute gouty arthritis.
