Feline leukemia virus is a retrovirus that infects cats. FeLV can be transmitted from infected cats when the transfer of saliva or nasal secretions is involved.
Solitary osseous plasmacytoma are rare neoplasms in humans and domestic animals. As such, there is a paucity of published information regarding diagnostic criteria, MRI findings, treatment modalities, progression, and remission of disease in the feline patient. Most data are extrapolated from human medicine. Plasma Cell Neoplasms Although plasma cells are differentiated B lymphocytes, plasma cell neoplasms are treated as a distinct entity due to their manifestations and effects on the host. Plasmacytoma s are localized proliferations of plasma cells which can be cutaneous or, less commonly, at internal sites, particularly involving the intestinal tract, spleen, kidneys, and nervous system ... The histological appearance of feline extramedullary plasmacytomas (EMP) has been previously reported [6]. The tumors were composed mostly of differentiated plasma-cytic tumor cells with abundant cytoplasm and could be diagnosed on the basis of immunohistochemical -Ig light chains expression [6]. Learn about plasma cell tumors in cats, including symptoms, treatments, and care strategies for your feline friend. Practitioners should be aware of feline plasmacytoma characterized by lymphoma-like cytologic and histologic features. The present study is valuable in providing the first clinical evidence that proves the immunogenicity of feline plasmacytoma.

How are extramedullary plasmacytomas diagnosed in cats? The histological appearance of feline extramedullary plasmacytomas (EMP) has been previously reported . The tumors were composed mostly of differentiated plasma-cytic tumor cells with abundant cytoplasm and could be diagnosed on the basis of immunohistochemical -Ig light chains expression . Is lymphoplasmacytic lymphoma a differential diagnosis of extramedullary cutaneous plasmacytoma in cats? These results emphasize the importance of lymphoplasmacytic lymphoma as a differential diagnosis of extramedullary cutaneous plasmacytoma in cats. KEY WORDS: feline, lymphoplasmacytic lymphoma, skin. Lymphoplasmacytic lymphoma (LPL) has been described in both veterinary and human medicine. How common is feline leukemia (FeLV) in cats? Feline leukemia virus (FeLV) is one of the most common and important infectious diseases in cats, affecting between 2-3% of all cats in the United States and Canada. Infection rates are significantly higher (up to 30%) in cats that are ill or otherwise at high risk (see below). What is the prognosis of plasma cell tumors composed of amyloid? Plasma cell tumors composed mostly of amyloid are termed amyloidomas in humans, where they have an excellent prognosis.1,16 The amyloid aggre- gates are proposed to be toxic to the neoplastic plasma cells, resulting in a mass composed of mostly amyloid.16 It is unclear if these tumors arose in the skin, bone marrow, or other tissue in this area.
