A young Japanese female demonstrated unusual features of Cushing's syndrome, cardiac myxomas and mucocutaneous lentigines. At the age of 12 years she presented with growth failure and obesity. The dexamethasone suppression test, the metyrapone test and low corticotropin concentrations indicated a primary adrenal disorder. At surgery, the adrenal glands were not enlarged (the right, 4.0 g; the left; 4.5 g) but had numerous small dark brown nodules. The pathological findings showed multiple small black cortical nodules containing large cells with eosinophilic cytoplasm and lipofuscin, and internodular cortical atrophy. These abnormalities were consistent with primary pigmented nodular adrenocortical disease. At age 22 years she complained of fatigue and palpitations associated with mid-chest pain. Four cardiac myxomas, suspected from the echocardiogram, were surgically removed. Because Cushing's syndrome and cardiac myxomas are life-threatening conditions, an awareness of the complex is important.

One of the most significant conceptual changes brought about by the analysis of circadian clock-deficient mice is that abnormalities in the circadian clock are linked not only to sleep arousal disorder but also to a wide variety of common diseases, including hypertension, diabetes, obesity, and cancer. It has recently been shown that the disruption of the two cryptochrome genes Cry1 and Cry2-core elements of the circadian clock-induces salt-dependent hypertension due to abnormally high synthesis of the mineralocorticoid aldosterone by the adrenal gland. This adrenal disorder occurs as a result of increased expression of Hsd3b6, a newly identified steroidogenic enzyme that regulates aldosterone production within the adrenal zona glomerular cells. Importantly, this enzyme is functionally conserved in humans, and the pathophysiologic condition of human idiopathic hyperaldosteronism resembles that of Cry1/2-deficient mice. This review highlights the potential utility of circadian clock-deficient mice as a tool for exploring hitherto unknown disease etiology linked to the circadian clock.
