  • COMMENTS:
    • Cattle have a lot of adrenal neoplasms, both of the cortex and the medulla. The clear nature of this tumor and multifocal hemorrhage is a bit more consistent with a pheo; adrenocortical tumors tend to be yellow-orange due to the fact that they produce steroids (of which oxidized lipid is a major component. Pheos may be part of a multiple endocrine tumor sydrome in bulls, along with C-cell tumors and occasionally pituitary tumors.
