Diagnosis and Management of Adrenocortical Carcinoma with co-secretion of Cortisol and Aldosterone
Adrenocortical carcinoma (ACC) accounts for 0.05-2% of all malignant tumors. Forty-five percent of ACCs with secretory function have excess glucocorticoids alone and only less than 1% secrete aldosterone. This is a case of a 44-year-old Filipino female with hypertension and a 12-year-history of...

| Summary: | Adrenocortical carcinoma (ACC) accounts for 0.05-2% of all malignant tumors. Forty-five percent of ACCs with secretory function have excess glucocorticoids alone and only less than 1% secrete aldosterone.
This is a case of a 44-year-old Filipino female with hypertension and a 12-year-history of an incidentaloma of the left adrenal gland, with recent-onset complaints of increasing abdominal girth, purple striae, amenorrhea, moon facies and a dorsocervical fat pad. Laboratory findings revealed low potassium levels, non-suppressed cortisol on dexamethasone test suggesting Cushing’s syndrome and elevated aldosterone-renin ratio and plasma aldosterone concentration pointing to primary hyperaldosteronism. A computed tomography scan revealed a left-sided adrenal mass measuring approximately 23 cm in largest diameter suggestive of carcinoma without metastasis or lymph node involvement. Complete resection via open adrenalectomy was performed and histopathologic assessment revealed Adrenocortical Carcinoma with Weiss score of 4. The Ki-67 proliferative index was found to be >20%. Radiotherapy was done as an adjuvant treatment.
Although rare, co-secretion of cortisol and aldosterone can occur in functional tumors of adrenocortical carcinoma. Malignancy should always be considered in patients who present with a history of a unilateral adrenal mass and/ or in those with signs and symptoms of adrenal hormone excess. Thus, a proper assessment derived from a thorough medical history, physical examination and laboratory work-up is warranted in patients with an adrenal mass to ascertain the diagnosis and provide adequate management.
