Hazards of laparoscopic adrenalectomy for Conn's adenoma. When enthusiasm turns to tragedy.

A 74-year-old man with primary aldosteronism had a small tumor (27 x 23 mm) of his right adrenal gland successfully removed by a transperitoneal laparoscopy. Despite absence of malignancy in the resected tumor and complete relief of all symptoms in the immediate postoperative period, recurrence occurred 6 months later. The tumor behaved as a carcinoma spread in the peritoneal cavity, and the patient eventually died with peritoneal carcinomatosis. We suggest that the laparoscopic technique coupled with pneumoperitoneum may have favored this recurrence.
