A CASE OF ANAPLASTIC MAMMARY CARCINOMA WITH PULMONARY METASTASIS IN A DOG.

A 10 year old dog was presented for necropsy with the history of sudden death. Post mortem examination revealed congestion with areas of red hepatisation in lungs. The left inguinal mammary gland was diffusely enlarged and the cut section revealed hemorrhagic areas with cystic spaccs. Large numbers of pleomorphic cells were observed in impression smear of the mass and condensed chromatins with prominent nuclci were also seen. Histopathological examination revealed anaplastic carcinoma with micrometastasis in lungs. Liver was yellow in colour and hard in consistency. The kidneys were atrophic with irregular surface.
