1/3. Peritoneal carcinomatosis following laparoscopic resection of an adrenocortical tumor causing primary hyperaldosteronism.

    A clinical syndrome combining hypertension and hypokalemic alkalosis led to the diagnosis of primary hyperaldosteronism, caused by a right-sided, 2 cm large, apparently benign aldosterone-producing adenoma. The adrenal tumor was completely resected by laparoscopic adrenalectomy. Six months after surgery, the patient exhibited a severe relapse of hyperaldosteronism. Extensive peritoneal metastases of a mixed aldosterone- and cortisol-secreting adrenocortical carcinoma were found at abdominal laparotomy. In the light of this case report, we discuss the possibility that laparoscopic resection of adrenocortical tumors might contribute to their subsequent peritoneal dissemination.

2/3. Co-secretion of aldosterone and cortisol by an adrenocortical carcinoma.

    We report a rare case of adrenocortical carcinoma. A 26-year-old woman presented with hypokalemia and hypertension due to hyperaldosteronism. She had no signs of Cushing's syndrome. Endocrinological data showed excess of aldosterone production and nonsupressible cortisol production on 2 mg of dexamethasone. magnetic resonance imaging showed left adrenal tumor. Transabdominal left adrenalectomy was performed and histopathological diagnosis was adrenocortical carcinoma. Her blood pressure and hypokalemia returned to normal after adrenalectomy. There is no recurrence after 36 months. We want to emphasis the importance of adrenal tests before the operation even if there are no signs of excess cortisol production.

3/3. adrenocortical carcinoma with concomitant myelolipoma in a patient with hyperaldosteronism.

    We present a case of aldosterone-secreting adrenocortical carcinoma with concomitant myelolipoma. To the best of our knowledge, this is the first such reported case. The patient was a 43-year-old man with severe hypertension. Clinical workup revealed an increased serum aldosterone level, hypokalemia, and metabolic alkalosis, and a left adrenal mass was found on computed tomography. The patient underwent a unilateral adrenalectomy, which led to improvement in blood pressure, the serum potassium level, and aldosterone concentration. The tumor weighed 70 g and measured 5.0 cm. On microscopic examination, we found necrosis, focal cytologic atypia, diffuse eosinophilic cells comprising more than 75% of the tumor, 5 to 7 mitotic figures per 50 high-power fields, rare atypical mitosis, and venous invasion. At the periphery of the tumor but within the capsule, microscopic areas of myelolipoma were seen. Ki-67 staining was positive in 20% of the tumor cells. Although rare, aldosterone-secreting carcinoma associated with myelolipoma should be included in the differential diagnosis of adrenal gland masses.
