ACTH-independent CS is occasionally caused by bilateral adrenocortical lesions, including unilateral functional adenoma with a contralateral non-functional mass, bilateral ACTH-independent macronodular adrenal hyperplasia (AIMAH), bilateral primary pigmented nodular adrenocortical disease (PPNAD), and an extremely rare entity, bilateral adrenocortical tumors [3]. Here, POMC is linked to Cowden syndrome 1.
