Conn’s adenoma on a field of celiac disease has never been described in the literature. We report a case of 31-year-old woman
with a history of celiac disease under gluten-free diet, and a pregnancy-induced hypertension controlled under treatment. She was
presented with hypertension crisis, hypokalemia and metabolic alkalosis. Diagnosis of primary aldosteronism (PA) was suspected,
which was confirmed by a decrease plasma renin, elevated plasma aldosterone level and high aldosterone/renin ratio additionally.
Adrenal computed tomography revealed left adrenal mass. The patient was treated with nicardipine, spironolactone and potassium
supplements. Laparoscopic left adrenalectomy was performed. The final diagnosis was adenoma of the adrenal gland consistent
with Conn’s adenoma. Blood pressure (BP) and hypokalemia returned to the normal level without any medication or supplement.
