Giant cell tumours

From Felipedia

Giant cell tumours of skeletal origin have been reported in the cat. They have been found to involve the distal femur and distal tibia, causing lameness and difficulty in walking[1].

Grossly and histologically, the tumor is similar to that described in the dog. Care must be taken in differentiation of primary giant cell tumors of medullary origin from the giant cell tumor of soft tissue, which may invade the underlying bone.
