Surgical approach in adrenal incidentalomas: Report of thirteen cases and review of the literature.

Abstract

OBJECTIVE The rate of adrenal incidentalomas detected in routine diagnostic imaging techniques is approximately 4-7%. Although the lesions are generally benign, carcinoma and functional adenomas can be diagnosed with careful clinic and laboratory evaluation. MATERIAL AND METHODS Data of 13 patients who underwent surgery for an adrenal mass between January 2010-June 2014 were analyzed retrospectively. RESULTS Seven (54%) patients were male, 6 (46%) were female, and the mean age was 38.2. The clinical diagnosis was pheochromacytoma in 5 patients (38.4%), non-functional adenoma in 5 (38.4), and metastatic lesion, Cushing syndrome, and adrenal carcinoma each in one patient (7.6%). Conventional open adrenalectomy was performed in 8 patients, while 5 patients underwent laparoscopic adrenalectomy. CONCLUSION Adrenal incidentalomas should be carefully evaluated for hormonal activity even if asymptomatic, and non-functional lesions should be considered as suspicious-for-malignancy. Laparoscopic adrenalectomy has become the gold standard for patients with a mass less than 6 cm, and without infiltration to adjacent organs.
