Plain-English summary
A 19.5-year-old male mongrel dog was brought in for worsening lameness and swelling around his right wrist. The vet discovered a tumor measuring 6 x 3 x 3 cm near the tendons in his forelimb. Thankfully, the tumor did not damage the joint, and after testing, it was identified as a rare type of cancer called synovial sarcoma, which arises from the tendon and its protective sheath. The dog’s treatment plan would depend on the specific recommendations from the veterinarian, but early diagnosis is crucial for the best outcome.

Abstract
A 19.5-year-old male mongrel dog developed a progressive lameness and swelling around the right carpus. A tumor (6 x 3 x 3 cm) was found in the caudal of distal antebrachium of the right forelimb, including tendons of the superficial digital flexor muscle and deep digital flexor muscle. No joint destruction was observed. The tumor consisted of round and spindle cells arranged in a compact sheet. There were occasional slit-like spaces or lumina, and areas rich in collagen fibers giving an appearance of tendon tissues. Neoplastic cells gave a positive immunoreaction to vimentin, but negative reactions to antibodies against S-100 protein, cytokeratin and myoglobin. Based on these findings, this tumor was diagnosed as a synovial sarcoma generating from the tendon and tendon sheath, which is very uncommon in dogs.
