Resumo: | Pheochromocytomas are uncommum tumors arising from the medular adrenal gland, which diagnosis is generally made at the necropsy. These tumors promote cardiac arrhythmias (increase), systemic hypertension and other clinical alterations that are attributed to the increase of the amount of catecholamines released by the tumor cells. This is a case of a fifteen years old female mongrel dog, brought to the Veterinary Hospital at UniABC, whose main complaint was intense itch, sleeplessness and considerable weight loss (12 kg in less than 3 months). The clinical examination showed bilateral mydriasis and deep cutaneous ulcer with muscle exposition, bilaterally in the toracic wall. Abdominal ultrasonography presented two oval solid formations, well-circunscribed, located next to the great vessels and at the cranial edge to left kidney, heterogeneous hipoecogenic aspect, with circumscribed inner anecogenic areas compatible with neoplasic formation in the left adrenal gland with metastases in the regional lumph node. The eletrocardiogram presented alternating wave "t" compatible with increase of cathecolamines. Two global masses of 2 and 4 cm diameter were removed, which was located cranialy to the left kidney, on the great vessels. Grossly, there were small circumscribed brown regions. The average arterial pressure during the surgery was of 150 mmHg and it fell down to 60mmHg during laparorraphy. During the first week after the surgery the dog started to sleep, was more calm and the itch almost disapeared. The diagnosis of pheochromocytoma was established with complementary examinations and concluded after the surgical removal and histopathologic examination. |

Estes promovem taquicardia, hipertensão e outras manifestações clínicas atribuídas ao aumento da quantidade de catecolaminas circulantes. Este trabalho relata o caso de um cão, SRD), fêmea de 15 anos de idade, atendido no Hospital Veterinário da UniABC, cuja queixa principal era prurido intenso e compulsivo, insônia e perda de peso considerável (12 Kg em menos de 3 meses). Ao exame clínico observouse midriase bilateral, ulcerações cutâneas com exposição de musculatura torácica bilateral. A ultrasonografia revelou a presença de duas formações sólidas ovaladas, de contornos definidos, localizadas próximo a grandes vasos e margem cranial de rim esquerdo, aspecto hipoecogênico heterogêneo com áreas anecogênicas em seu interior, compatível com formação neoplásica em adrenal e provável metástase em linfonodo regional. O eletrocardiograma apresentou onda "t' alternante compatível com aumento das catecolaminas circulantes. Foram removidas duas massas globosas de 2 e 4 cm de diâmetro, que se encontravam localizadas cranialmente ao rim esquerdo, sobre as artérias renal e aorta. Macroscopicamente visualizouse regiões circunscritas de coloração marrom. A pressão arterial média durante a cirurgia foi de 150 mmHg e no momento da laparorrafia caiu para 60 mmHg. Durante a primeira semana pós cirúrgica a proprietária relatou que o cão passou a dormir, ficou mais tranquila e o prurido diminuiu. O diagnóstico de feocromocitoma foi definido com os exames complementares e concluído após a remoção cirúrgica e exame histopatológico.Universidade de São Paulo.
