Abstract

ALMEIDA, T.M. et al. Lymphoma in leukemic phase in feline coinfected with feline immunodeficiency virus and feline leukemia virus: case report. Arq. Bras. Med. Vet. Zootec. [online]. 2019, vol.71, n.1, pp.219-224. ISSN 0102-0935.  http://dx.doi.org/10.1590/1678-4162-10382.

The present study aimed to report a case of lymphoma in leukemic phase in feline coinfected with feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV). Blood counts, reticulocyte counts, bone marrow avaluation, biochemistry, immunochromatography assay for FIV and FeLV, indirect immunofluorescence (IFA) for FeLV, thoracic radiography and renal citology were performed. This last examination revealed extranodal lymphoma. The association of the clinical signs with the infiltration of a high number of lymphoblastic cells in the bone marrow with cytomorphological criteria of malignancy, atypical mitoses, lymphoglandular corpuscles and hematopoietic material were determinant for the diagnostic conclusion. Lymphoma is a relatively common neoplasm in felines, however the leukemic phase is rare and may represent a clinical diagnostic challenge, making it essential to include bone marrow cytology in the clinical practice of this species.

Keywords : cats; clinical hematology; bone marrow; lymphoproliferative disorder.
