Ectopic adrenocortical tissue: an incidental finding during inguinal surgery in children.

Adrenal rests are usually unrecognized during operation, and the incidence of ectopic adrenal cortical tissue in pediatric patients during inguinal surgery procedures is unknown. We performed 3028 groin surgical explorations in 2680 patients aged 1 month to 17 years. Ectopic adrenal tissue was found in 69 inguinal operations (2.2%): 37 during 1.524 orchiopexy (2.4%), 23 during 1.115 herniectomy (2.0%), and 9 during 389 hydrocoela operation (2.3%). Statistically there were no significant differences among those three groups. No adrenal rests were detected in females. Although a few reported cases with hormonal activity of ectopic adrenocortical tissue (EACT), the recommendation is to remove them if found.
