Osteochondroma in a young cat infected by feline leukemia virus
ABSTRACT: Osteochondromas are primary bone tumors characterized by cartilage-covered bone projections involving single or multiple masses (osteochondromatosis). This study reports the clinical and pathological findings from a young domestic cat with osteochondroma in the humerus. During the clinical evaluation, the animal had pronounced right forelimb musculature atrophy and an increased distal humeral volume. Histopathological examination of the neoplasm revealed a proliferative lesion characterized mostly by endochondral ossification and peripheral foci of proliferating cartilage tissue. Further testing using immunohistochemical staining and polymerase chain reaction revealed the presence of feline leukemia virus antigens in the hematopoietic cells of the bone marrow and FeLV proviral DNA in the peripheral blood lymphocytes. Clinical and pathological findings are consistent with osteochondroma. This neoplasm occurred in an eight-month-old feline with humeral enlargement that had been present since two months old.
