Chondrosarcoma

From Felipedia

Chondrosarcoma is an uncommon tumor in the cat. Affected animals range in age from 2 years to 15 years, with a mean age of 8.8 years. The tumor has been reported to arise from the scapula, humerus, skull, femur, foot, tibia, and pelvis^[1].

Subcutaneous variants can form as a result of the feline fibrosarcoma complex^[2].

Chondrosarcomas are firm, rapidly growing masses attached to the underlying bone; they cause lameness and are painful on palpation. Grossly and histologically, the tumor is similar to that described in the dog. Metastasis to the lungs has been found in 10% of the cases.
