A case of seminoma found in an adult guinea fowl (Numida meleagris)
that was exhibited in a zoo is reported. The right testis was extremely
enlarged and replaced by round and polyhedral pleomorphic neoplastic
cells that showed nest, sheet, and diffuse growth patterns. The
neoplastic cells had acidophilic cytoplasm and hyperchromatic and
eccentrically placed nuclei. Metastatic lesions composed of diffuse
growth of neoplastic cells similar to those of the primary tumor were
seen in the liver, lungs, kidneys, and heart, and neoplastic emboli were
often detected within blood vessels of these organs, indicating
hematogenous metastasis. This is the first report of malignant seminoma
with multiple metastases in the visceral organs in the guinea fowl.
