Hyperaldosteronism in an adolescent with Gardner's syndrome.

Gardner's syndrome, a variant of familial adenomatous polyposis, is characterized by colonic polyposis, osteomas, and soft tissue tumors. Adrenal masses in Gardner's syndrome are rare, and few have displayed clinical manifestations. We report a 16-year-old female with Gardner's syndrome, who had an aldosterone-secreting tumor resected via laparoscopic adrenalectomy.
