Plain-English summary
A 13-year-old Morgan gelding was brought in for lameness in his right front leg and swelling in the area around his carpal joint (wrist). After examining the horse, vets found a soft tissue mass in the tendon sheath using ultrasound. They performed surgery to remove the mass, which turned out to be a mast cell tumor. Unfortunately, 22 months later, the horse showed mild lameness again due to a recurrence of the tumor. Treatment included surgery, rest, and corticosteroids to help manage the condition.

Abstract
A 13-year-old Morgan gelding was examined for right forelimb lameness and tenosynovitis of the right common carpal sheath of the digital flexor tendons. The horse had moderate right forelimb lameness at the trot and marked effusion of the right common carpal sheath of the digital flexor tendons. Ultrasonographic examination revealed a soft tissue mass within the proximal pouch of the affected tendon sheath, located adjacent to the distal physis of the radius. Cytology and culture of the fluid revealed a sterile, eosinophilic tenosynovitis. Tenoscopic exploration confirmed the presence of a capsulated soft tissue mass. Thecotomy was required to fully debride the mass, which histology revealed to be a mast cell tumour. At 22 months postoperatively, the horse developed mild right forelimb lameness and eosinophilic tenosynovitis because of recurrence of the mastocytoma. Mastocytosis is a possible differential diagnosis in any horse exhibiting lameness associated with tenosynovitis. Surgical excision combined with rest and postoperative intrasynovial and systemic corticosteroids may be palliative.
