A solitary extraskeletal osteochondroma was diagnosed in a 6-year-old, castrated male Burmese cat, positive for feline leukaemia virus (FeLV). The cat presented with a rapidly growing, solid, non-painful mass on the craniolateral aspect of the left elbow. Radiographs revealed an oval, well circumscribed 2.0 cm × 1.5 cm × 1.5 cm mineralised mass separated from the underlying bone. Surgical excisional biopsy confirmed the diagnosis. Feline extraskeletal osteochondromas are benign tumours frequently seen in FeLV-positive cats which can transform into osteosarcomas or chondrosarcomas. Radiographically, they cannot be distinguished from a parosteal or an extraskeletal osteosarcoma.
一只6岁已去势的雄性缅甸猫被诊断患有孤立性骨外骨软骨瘤，该猫感染猫白血病病毒（FeLV）呈阳性。这只猫的左肘颅外侧出现一个快速生长的、坚实的、无痛性肿块。X线片显示一个椭圆形、边界清晰的2.0厘米×1.5厘米×1.5厘米矿化肿块，与下方骨骼分离。手术切除活检确诊了该诊断。猫骨外骨软骨瘤是FeLV阳性猫中常见的良性肿瘤，可转变为骨肉瘤或软骨肉瘤。在X线片上，它们无法与骨旁骨肉瘤或骨外骨肉瘤区分开来。
