Lymphosarcomas are lymphoid neoplasms which arise in a solid organ and which, in dogs, have an yet undetermined etiology. A lymphosarcoma can be diagnosed both by cytology and histopathology, although often its differentiation from lymphoid leukemia can be difficult. Several signs are associated with canine lymphosarcomas and they vary according to the compromised organ. A common manifestation is generalized lymphadenopathy which should be differentiated from other diseases that cause enlargement of lymphnodes. Some paraneopastic syndromes may compound cases of lymphosarcoma and are often the cause of the animal’s death. This paper reviews the clinical, laboratorial, gross and histopathological aspects of canine lymphosarcoma.
