Feocromocitoma em cadela SRD - Relato de caso

Abstract

Phe ochromocytoma is a rare tumor of neuroendocrine origin that affects the adrenal medulla of the adrenal gland, and is responsible for systemic clinical manifestations due to the excessive production of catecholamines. The antemortem diagnosis of pheochromocytoma in dogs is challenging, due to the nonspecific nature of the clinical signs, the presence of comorbidities, and the limitation of specific diagnostic methods. Due to its lethal potential, early diagnosis is essential for patient survival. It is a neoplasm that can occur unilaterally or bilaterally, functional or non functional, with may exhibit benign or malignant behavior. In dogs, the unilateral form predominates, and the clinical signs are usually due to the excess of catecholamines, as well as mass effect and local invasion. It is estimated that about 50% of affected dogs are asymptomatic, and the diagnosis is often incidental, identified during necropsy or surgical interventions for other causes.
