Malignant neoplasms occur commonly in cattle, with lymphosarcoma being the most common. Chondrosarcoma rarely has been described and only in mature cattle. The present report describes a chondrosarcoma of the left scapula of an 8-month-old Holstein steer. Histologic examination of the mass revealed an unencapsulated, multilobular neoplasm composed of neoplastic spindle cells embedded in irregular islands of chondroid matrix, consistent with a diagnosis of chondrosarcoma.
