Ectopic adrenal in inguinal hernia sacs.

Nodules of the ectopic adrenal cortex were identified in hernia sacs in 5 men. This condition seems to result from developing adrenal cortical tissue accompanying a descending testis. Ectopic adrenal must be distinguished from metastatic clear cell carcinoma. Such ectopic foci could potentially result in neoplasms or be a source of hormone production after adrenalectomy.
