Osteosarcoma of the patella was diagnosed by biopsy in a 9-year-old, male dog of mixed breeding. The dog was originally examined because of intermittent lameness of the left hindlimb; there were minimal palpable abnormalities of the stifle. After the diagnosis, the owner refused further treatment for the dog. The dog was reexamined 13 months later because of a marked swelling of the stifle. The dog was euthanatized and necropsy findings confirmed the diagnosis.
一只9岁的混血雄性犬经活检被诊断为髌骨骨肉瘤。该犬最初因左后肢间歇性跛行接受检查；膝关节处可触及的异常极小。诊断后，犬主拒绝为其进一步治疗。13个月后，该犬因膝关节明显肿胀再次接受检查。随后对其实施安乐死，尸检结果证实了诊断。
