title: Recognition of feline parovarian nodules as ectopic adrenocortical tissue.
abstract: Parovarian nodules encountered during ovariohysterectomy were identified histologically as ectopic adrenocortical tissue. Specimens were examined from 17 healthy female cats aged 6 months to 5 years. The structures were gold to tan, 2 to 5 mm in diameter, and located in the broad ligament within 4 cm of the ovary. Their histologic appearance resembled normal adrenal cortices, with remnants of mesonephric tissue. Adrenal medullary tissue was not found.
