Abstract

A carcinoid is a rare neoplasm derived from neuroendocrine cells that may arise in the hepatobiliary system. This report described two cases of carcinoid of the gallbladder in dogs, with emphasis on the clinical, pathological and immunohistochemical aspects. Case 1 was a 10-year-old female Shih Tzu, with a history of prostration and occasional episodes of diarrhea and vomiting. Case 2 was a 10-year-old male Cocker Spaniel, with a history of diarrhea and abdominal pain. Abdominal ultrasonography suggested a neoplasm of the gallbladder in both cases. The dogs underwent cholecystectomy, and 10% formalin-fixed samples were sent for pathological examination. Histologically, a neoplastic proliferation of neuroendocrine cells was observed in the gallbladder submucosa of both cases. Immunohistochemical labeling for neuroendocrine antibodies, such as synaptophysin, neuron-specific enolase and chromogranin A, confirmed the diagnoses. Carcinoid of the gallbladder is a rare neoplasm in dogs, without specific clinical signs, but should be included in the differential diagnosis of lesions that affect this organ.
