A case of renal myelolipoma and amyloidosis associated with osseous metaplasia in a 14 day old broiler chicken in an experimental group is described. Beginning with their 6th day of life, forty broiler chickens (Ross 308) were randomly separated into two groups of 20 subjects each. The experimental group was treated with ochratoxin A (OTA) for 21 days (50 µg/kg/day) and the other one constituted the control group. Histological examination of the kidney revealed a proliferation of mature adipocytes, accumulation of numerous myelocytes, erythroblasts, eosinophilic myelocytes and heterophils, delimited by an osseous tissue surrounded by renal parenchyma. A similar ectopic metaplastic tissue was observed in the lungs. Additionally, in kidneys, skin and liver an amorphous deposit of amyloid was observed.
