Feline primary bone lymphoma: A case report

Abstract

The incidence of cancer lesions has increased in recent years, with lymphoma being the most common neoplasm in cats in the clinical routine, affecting about 50% of all hemolymphatic tumors in cats. This increase occurs in a multifactorial way, one of the main ones being the longevity of pet animals. The precise etiology of feline lymphoma is not known in many cases; however, viral causes of feline lymphoma are well defined, with infections by both feline leukemia virusand feline immunodeficiency virus. Lymphoma consists of a malignant neoplasm of lymphocytic origin, characterized by the clonal proliferation of malignant lymphocytes, originating mainly from lymphoid organs, such as bone marrow, spleen and lymph nodes. Lymphocytes are part of our immune system and are distributed throughout the body. Lymphoma can be classified as multicentric originating in the lymph nodes, thymic, hepatic, splenic, gastrointestinal and extra nodal lymphomas cutaneous, nasal, renal and nervous system lymphoma. The most common symptoms are weight loss and appetite and gastrointestinal signs: vomiting and diarrhea.
