Nephroblastoma in Giriraja (Gallus domesticus) - A case report

Carcass of an year old female Giriraja brought from the University Poultry Farm, on autopsy revealed large yellow gray lobulated mass which replaced most of the right kidney tissue. Based on the histopathological examination, the tumour was diagnosed as nephroblastoma. Kidney mass revealed tubules of varying sizes lined by single to multiple layers of hyper-chromatic vesicular cells within a fairly predominant connective tissue stroma and undifferentiated glomeruli.
