Amputação de dígito devido a mastocitoma de grau 2 canino - relato de caso

Abstract

Mast cell tumor is one of the most common cutaneous neoplasms in dogs, presenting variable biological behavior and malignant potential. This study aimed to report a case of a grade 2 mast cell tumor located in the digit of a 1-year-and-8-month-old Shih-tzu dog treated at a veterinary clinic. The diagnosis was established through clinical, laboratory, and histopathological examinations. The chosen treatment consisted of digit amputation associated with electrochemotherapy and adjuvant chemotherapy, aiming at better tumor control and reduction of recurrence. The patient showed a good therapeutic response, with satisfactory clinical evolution and favorable prognosis during follow-up. It is concluded that mast cell tumors, despite their unpredictable behavior, may have a favorable prognosis when diagnosed early and treated appropriately. The combination of therapeutic approaches is essential to improve treatment effectiveness and the animal’s quality of life.
