| ABSTRACT: 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. |

| Chondrosarcoma is a malignant mesenchymal tumor in which the neoplastic cells produce cartilaginous matrix and is uncommonly described in birds. This report describes the clinical and pathological findings of one case of chondrosarcoma in a blue-fronted parrot (Amazona aestiva). Macroscopically a 3.6x3.5x1.8cm, nodular, ulcerated, and firm mass was identified in the dorsal synsacrum. Microscopically, the mass was composed of a monomorphic proliferation of pleomorphic spindle chondrocytes with abundant cartilaginous matrix, consistent with chondrosarcoma |
