Mast cells are tumors originating from mast cells which usually affect cats and dogs. They may have benign behavior, however, this will depend on the degree of the neo-plasm and its staging. In cats, two patterns have been described clinically: visceral and cutaneous, of which the cutaneous form is the most frequent, reaching metastasis to adjacent organs and even affecting the spleen and / or intestine in more differentiated stages. A case of a mastocytoma is presented, a feline corresponding to a mongrel specimen with a clinical picture of onset of more than two months of evolution, consisting of the appearance of an allopecal plaque, ulcerated and elevated in the interscapular region, accompanied by pruritus that presented spontaneous resolution. Through the clinical course, he was immunized against the rabies virus, later the appearance of a nodular lesion of unusual subcutaneous characteristics, 2 cm in diameter, was observed. According to the evolution time and the vaccination history, it was decided to perform a biopsy and surgical resection. The biopsy report confirmed the diagnosis of Patnaik's histological grade 3 mastocytoma, taking into account the histological and structural characteristics and its clinical behavior. The case was followed up after eight months, where an improvement in the clinical picture was evident, without the appearance of a new mass suggestive of neoplasia, without metastatic findings to other structures, with successful healing of the surgical wound and satisfactory evolution.
