Cushing’s syndrome is a clinical disorder caused by overproduction of cortisol. Adrenal adenoma is the cause in 5% of cases of Cushing syndrome. ACTH-independent Cushing’s syndrome in 90% is caused by unilateral adrenal tumors. Of these, adenomas are the cause in 80% of the cases, while the others are adrenocortical carcinoma. Rare causes of Cushing’s syndrome include adrenal hyperplasia. Overproduction of cortisol results in weakened protein structures leading to protuberant abdomen and poor wound healing, glucose is converted to fat and deposited in the abdomen, supraclavicular fossa and cheeks. Other presentations are diabetes, hypertension, osteoporosis, fractures, impaired immune function, glucose intolerance, and psychosis. We report a 21-year-old female who presented with clinical symptoms of newly diagnosed hypertension and diabetes mellitus which after poor response to treatment she was evaluated and diagnosed to have Cushing syndrome. She subsequently had left adrenalectomy and did very well with resolution of patients’ symptoms. The histology came out to be diffuse adrenal hyperplasia.
