Pathology of giant lipoma in a non-descript dog: A case report

A nine years old non-descript male dog was presented to Veterinary Clinical Complex, Namakkal with the history of progressively growing mass at the neck region. On clinical examination, a large firm mass with irregular surface was noticed in the right prescapular region of the animal. Fine needle aspiration cytology (FNAC) exhibited that there were large number of lipid globules along with adipocytes with eccentrically placed flat nuclei. The tumour mass was excised surgically and weighed around 3.16 kilograms. There were yellow, soft, lobulated masses with oily surface noticed on incision. Histopathological examination revealed the mature adipocytes with eccentrically placed nuclei without mitotic figures. The case was confirmed as lipoma based on cytology, gross and histopathological examination.
