| 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 |

| ABSTRACT: A three-year-old female African pygmy hedgehog (Atelerix albiventris), born and domiciled in Brazil, presented apathy, prostration, and difficulty to stay standing. Its parents were siblings but did not present clinical signs related to this condition. As its clinical condition worsened, the animal was euthanized and referred for necropsy. No gross lesions were found in the central nervous system (CNS). Histologically, there was vacuolation with axonal degeneration in the white matter of the CNS and in peripheral nervous tissue. The Kluver-Barrera (KB) stain confirmed demyelination in vacuolated areas. Immunohistochemistry using several neural markers confirmed astrocytosis and microgliosis associated with vacuolated areas. In addition, there... |

| This report describes the clinical, pathological and microbiological findings of an uncommon infection in a cat by Nocardia nova. A 3-year-old male domestic short hair cat with an ulcerated and exudative cutaneous wound was presented for clinical examination. Samples were collected for histopathology and bacteriology diagnosis. Microscopically, the lesion was diagnosed as pyogranulomatous dermatitis and panniculitis with large and irregular colonies of branching filamentous bacterium. Skin bacteriological culture showed gram-positive rods and partially acid-fast branching filaments by gram and kinyoun staining, respectively. The identity of Nocardia nova was confirmed by 16S rDNA sequencing and phylogenetic analysis. This is the first case of... |
