Uso da eletroquimioterapia como adjuvante a excisão de mastocitoma pela técnica de cirurgia reconstrutiva: relato de caso.

Abstract

Mast cells are connective tissue cells that play a fundamental role in the immune system, with the main site being the subcutaneous tissue and the mucosa. They are considered the only hematopoietic cells to spend most of their life in tissues. Mastocytoma is one of the most common cutaneous neoplasms in dogs, representing 11 to 27% of malignant neoformations in the species. It is characterized by abnormal and overgrowth of mast cells. The diagnosis of mast cell tumor is based on cytological and histopathological examinations. The treatment of choice consists of surgical removal of the neoplasm, however, depending on the case, other treatments can be used as an adjuvant to surgery. The objective of this monograph is to report the case of mast cell tumor in an 8-year-old canine patient treated during my internship at the veterinary hospital of UFRPE, with a history of lameness and the presence of neoformation in the lateral region of the thigh of the left hind limb. The diagnosis was established by performing fine needle aspiration cytology and the treatment consisted of surgical excision associated with electrochemotherapy as an adjuvant therapy.
