A 56-year-old woman presented with an incidental adrenal adenoma and physical examination findings that included moderate obesity, a slight cervicothoracic fat pad ("buffalo hump"), increased supraclavicular fat pads, and white abdominal striae. Biochemical workup revealed elevated levels of 24-hour urinary free cortisol but normal serum morning cortisol and suppressed levels of corticotropin, suggestive of adrenal-dependent Cushing syndrome. The resected adrenal gland revealed macronodular cortical hyperplasia with a dominant nodule. Other findings included an absent cortisol response to corticotropin stimulation, presence of serum anti-21-hydroxylase antibodies, and mononuclear cell infiltration-consistent with adrenalitis. The findings represent, to the authors' knowledge, the first known case of a patient with coexistent functional cortisolsecreting macronodular adrenal tumor resulting in Cushing syndrome and immune-mediated adrenalitis resulting in Addison disease.
