Terapeutica en linfoma cutaneo no epiteliotropico en un gato domestico de la ciudad de quito, reporte de caso

Abstract

Feline cutaneous lymphoma is an extranodal type neoplasm, with two forms of clinical presentation; Epitheliotropic and non-epitheliotropic lymphoma, the gold standard is histopathology for diagnosis, together with special techniques such as immunohistochemistry. The established treatment for cutaneous lymphoma varies according to the presentation of the lesions. If they are local, they are treated with surgery with a better prognosis, or diffuse with or not systemic invasion, treated with chemotherapy or radiotherapy. The objective of this research was to describe the oncological therapeutic response in a feline patient, who presented with nodular, ulcerated skin lesions with edema and inflammation on the face, ears, and front limbs. The histopathological diagnosis was non-epitheliotropic cutaneous lymphoma, where the microscopic analysis revealed infiltration of lymphocytes of various sizes, expanding and infiltrating the interstitial dermis with edema and fibrosis. The COP protocol (vincristine, cyclophosphamide, and prednisolone) was the chosen treatment for this patient. In the methodology used, a clinical and descriptive assessment of the patient’s skin lesions was carried out.
