Abstract

Extraskeletal myxoid chondrosarcoma was diagnosed on the ventral abdomen of a kudu with metastasis to the omentum and lungs. Histopathological examination of the large (20 cm × 10 cm) primary, multinodular, moderately cellular neoplastic mass was characterised by neoplastic mesenchymal cells arranged in strands and bundles, interspersed by multiple foci of cartilage immersed in a myxoid matrix. The neoplastic cells revealed diffuse vimentin and S100 positivity and the myxoid matrix was positive with Alcian blue. The microscopic examination in addition to the Alcian Blue and immunohistochemistry findings confirmed the diagnosis.
