BILATERAL ADRENOCORTICAL CARCINOMA: CASE REPORT AND REVIEW OF LITERATURE.

Adrenocortical carcinoma is a very rare and aggressive endocrinological malignancy arising from the adrenal cortex. The estimated incidence is 1 per million people, with an estimated 5-year survival rate of 16-47%. It can be bilateral in roughly 2-10% of cases, but the data is scarce and there is no conclusive evidence whether the contralateral mass is an independent tumor or a metastasis from the other adrenal gland cancer. Radical surgical excision is the only curative treatment. Therefore, careful pre- and intraoperative surgical planning is critically important. Open adrenalectomy has historically been the gold standard approach for surgical treatment of adrenocortical carcinoma. Laparoscopic adrenalectomy has emerged as a minimally invasive alternative, but its oncological safety and effectiveness has long been under debate. Current evidence suggests that in experienced hands laparoscopic adrenalectomy is as safe and effective as its open counterpart in the treatment of localized adrenocortical carcinoma and the adrenal masses ≤10 cm. Urologists have been tempted to apply laparoscopy also to bilateral disease, although the need to reposition the patient and a longer operative time can be limitations. Given the rarity of adrenocortical carcinoma and the lack of quality evidence for the bilateral disease, we used the conventional narrative strategy to review the available literature. We also report a case of nonfunctioning bilateral adrenocortical carcinoma in a 65-year old man, who was operated on with simultaneous bilateral laparoscopic adrenalectomy for suspected localized (stage 2) disease, which proved to be bilateral locally advanced carcinoma (stage 3). Postoperatively, the disease rapidly progressed to the fatal outcome. The case once again highlights the importance of detailed operative planning and the need of imaging studies as close as possible to the date of planned surgery.
