Abstract
This case report aims to describe how Electrochemotherapy as well as other joint actions such as neoadjuvancy, surgical resections and chemotherapy, have acted in the treatment of a 13-year-old dog diagnosed with Grade III Mastocytoma, a high degree of malignancy. The choice of the best therapy as well as the right moment for each process was based on the examination of fine needle aspiration cytology (CAAF) and confirmed by the histological specification of both the lesion and the regional lymph nodes. Known as a round cell tumor, mastocytoma is part of the group of neoplasms consisting of mast cells, of cutaneous or visceral origin. They are more common in dogs, representing 7% to 21% of skin tumors, of these 11% to 21% have malignant skin variations. As in this report, about 45% of cases occur in the pelvic limbs, perineum region and genitalia. Records point to cases in dogs with an average age of 8 years, but there are already reports in which the tumor reached younger canines, from 6 years old.
