Surgical Excision as Treatment for Lipoma in Domestic Cats: A Case Report

Abstract

Lipomas are benign tumors derived from mature adipocyte tissue and are common in domestic animals, although less frequently reported in cats than in dogs.This case report aims to describe the results of hematological and cytological examinations (fine needle aspiration biopsy/FNAB) and the surgical removal of a lipoma in a female domestic cat with a mass in the hypogastric region.Hematological examination revealed mild leukocytosis and lymphocytosis, indicating a mild chronic inflammatory process, and thrombocytopenia, suspected to be related to local consumption or sampling artifact.Cytological examination of FNAB showed a predominance of small-nucleated adipocytes with cytoplasm containing large fat vacuoles, without pleomorphism or mitotic activity, accompanied by a few inflammatory cells such as lymphocytes and macrophages, thus supporting the impression of a benign lipoma.Surgical procedure was performed through total excision with a longitudinal incision along the mass, followed by layered wound closure using absorbable and non-absorbable sutures to minimize dead space formation.Postoperative results showed good wound healing without significant complications.These findings are consistent with previous reports that lipomas in cats have a good prognosis if complete excision is performed.In conclusion, the diagnosis of lipoma can be confirmed through clinical examination and FNAB, while surgical excision remains an effective and safe definitive treatment option to prevent recurrence.
