Abstract
Metastatic adenocarcinoma of unknown primary origin was incidentally detected in the skeletal muscles of a male sheep slaughtered for meat consumption. The tumour grossly appeared as multiple spherical whitish nodules embedded within the longissimus dorsi and psoas muscles of the internal abdominal wall. Microscopic examination of the nodules revealed scattered lobular masses of glandular structures trapped in-between the skeletal muscle fibres. The lobular masses were composed of neoplastic proliferations of epithelial cells arranged in the form of distinct acini separated by fibrous connective tissue stroma. The acinar cells were mostly cuboidal or short columnar in shape with foamy cytoplasm and hyperchromatic nuclei. The tumour masses were loosely demarcated from adjacent muscular tissue by thin fibrous connective tissue capsule.
