The role of cytology in the differential diagnosis of lymphadenopathies in dogs

Abstract

The present study aims to highlight the role of the cytological examination in the differential diagnosis of lymphadenopathy in dogs. The study was performed on forty dogs diagnosed with lymphadenopathy in the Teaching Veterinary Hospital of the Faculty of Veterinary Medicine of Bucharest. The samples were obtained by fine needle aspiration technique (FNA), the smears were done by stretching technique, and May-Grunwald Giemsa staining was used. The smears were examined under an optical microscope with 200, 400, and 1000 magnification. The role of the cytological examination in the case of lymphadenopathy in dogs is essential because it can provide a quick, simple, minimally invasive and, in most cases, definitive diagnosis. All the cases included in the study had definitive diagnostics using cytology, confirming cytology examination's accuracy and specificity in evaluating dogs' lymph nodes.
