Multicentric fibrosarcoma in a cat and a review of the literature.
A case of multicentric fibrosarcoma in a ten month old domestic short-haired cat is presented and discussed. Tumor tissue was found to involve the right distal forepaw, right shoulder area and a popliteal lymph node. This anaplastic neoplasm was concentrated primarily in subcutaneous tissues but also extended to muscle, bone and lung. The cat was found to be positive for feline leukemia virus by the ELISA test. Based on these findings, it is likely that the lesions in this case result from an interaction between the feline leukemia virus and feline sarcoma virus.
