Plain-English summary
A 3-year-old Hanoverian-cross filly developed lumps under her skin on her chest two months after having surgery for colic. Six months later, she was brought in because she was limping badly. Tests showed that her joint had abnormal fluid and some unusual cells, and X-rays revealed joint damage. Sadly, to prevent her from suffering further, she was put to sleep, and an examination after death found multiple soft tissue masses and a type of cancer called cutaneous lymphoma, which affected the areas around her joints but was not linked to her joint problems. The treatment did not work, as the filly was euthanized due to her condition.
Abstract
Two months after colic surgery, subcutaneous masses were found on the ventral and lateral portions of the thorax of a 3-year-old Hanoverian-cross filly. Six months later, the filly was admitted for evaluation of severe lameness. Arthrocentesis of the tarsocrural joint yielded clotted sanguineous material; however, unusual multinucleated giant cells were seen. Radiography of the right tarsus revealed soft tissue opacity and degenerative joint disease. The filly was euthanatized to prevent further suffering. At necropsy, multiple soft-tissue masses were located throughout the fascial planes of the tarsi and in the subcutis of the ventral and lateral portions of the thorax. Neoplasms consisted primarily of a large number of mature well-differentiated T lymphocytes. On the basis of these findings, the diagnosis was cutaneous lymphoma with unusual involvement of periarticular tissues. Severe degenerative joint disease in the right tarsus did not appear to be associated with the tumors.
