Mastocitose cutânea felina: relato de caso

Abstract

A mastocytosis is a group of diseases characterized by the growth, survival time, and/or abnormal proliferation of mast cells in the skin or systemically. Mast cell changes that are restricted to the skin are called cutaneous mastocytosis and can present as simple pruritic nodular lesions as in the case of non-neoplastic cutaneous mastocytosis and more aggressive lesions linked to cases of cutaneous mastocytoma. Non-neoplastic cutaneous mastocytosis affects younger animals instead of mastocytoma, which affects older animals. Cytology and histopathological analysis are considered the most effective and important diagnostic techniques to direct the therapeutic conduct, with surgical recession and/or chemotherapy as the treatments of choice. The present study aims to report a case of cutaneous mastocytosis in a young cat that presented recurrence even after compliance with the therapeutic protocols. The patient presented reddish nodules on the limbs, but without pruritus; the diagnosis was made with cytology and histopathology. The initial therapeutic approach was surgical removal of the nodules, followed by electrochemotherapy and conventional chemotherapy.
