Hepatic Myelolipoma with systemic amyloidosis in a goose (Anser cygnoides domesticus).
We report here a case of hepatic myelolipoma with systemic amyloidosis in a goose (Anser cygnoides domesticus), which died suddenly following the short history of weakness and greenish diarrhea. At necropsy, multiple yellowish-white foci were observed on the surface of the prominently enlarged liver. Histologically, there were multiple foci of adipose tissue admixed with myeloid elements in various proportions in the liver as well as amyloid deposition in several organs including the liver, intestine, spleen, kidney, and ovary. Ultrastructurally, erythroblast-like cells and myelocytes, which showed various stages of differentiation, were observed in the foci of the liver. These findings shared characteristics of hepatic myelolipoma which is very rare in birds.
