Plain-English summary
An older Thoroughbred stallion was brought in for examination due to worsening lameness, swelling in his knee area, and weight loss. X-rays showed a damaging growth in the lower part of his radius bone. A biopsy confirmed that he had chondrosarcoma, a type of cancer that affects cartilage. Further examination after he passed away revealed that the tumor was aggressive, spreading into nearby joint structures and bones. Unfortunately, this type of tumor is serious and invasive, indicating a poor prognosis.
Abstract
An aged Thoroughbred stallion was examined because of progressive lameness, carpal swelling, and weight loss. Radiography revealed a destructive lesion in the caudomedial, distal portion of the radius. Chondrosarcoma was diagnosed by tumor-core biopsy. Gross and histologic evaluation of the neoplasm after necropsy revealed a locally invasive chondrosarcoma at the distal end of the radius that infiltrated the radiocarpal joint capsule and invaded the carpal bones. The malignant nature of this tumor was evident by its invasiveness and histologic features of cell pleomorphism and presence of mitotic figures.
