Description
Summary:Primary gallbladder neoplasms occur infrequently in domestic animals and rarely in wild animals. This article describes a case of gallbladder adenoma in a mongoose ( Mungos mungo) in captivity. Grossly, the gallbladder was moderately distended with a smooth capsular surface. Necropsy showed an irregular, soft, whitish nodule 0.8cm in diameter. Microscopic examination of the nodule showed proliferation of epithelial cells, which projected from the mucosa and formed papillary projections supported by a sparse fibrovascular stroma. Neoplastic cells were well differentiated with mild anisocytosis and anisokaryosis. Based on these histopathological findings, adenoma of the gallbladder was diagnosed. RESUMO: Neoplasmas primárias de vesícula biliar são incomumente descritas em animais domésticos e, raramente, afetam animais silvestres. Este trabalho tem por objetivo descrever um caso de adenoma de vesícula biliar em mangusto ( Mungos mungo) mantido em cativeiro. Macroscopicamente, a vesícula biliar estava moderadamente distendida, com superfície lisa e, em seu interior, havia um nódulo esbranquiçado, irregular, macio, de 0,8cm de diâmetro. Microscopicamente, havia proliferação neoplásica, epitelial, bem diferenciada, com projeções papilares da mucosa contendo células cilíndricas. Observou-se anisocitose e anisocariose leve. Com base nos achados histopatológicos, foi firmado o diagnóstico de adenoma de vesícula biliar.
