Secondary causes of diabetes are uncommon but early recognition is important so that patients receive appropriate diagnosis and treatment. Cushing’s syndrome is a rare disorder which is associated with weight gain, diabetes and hypertension. Since obesity is common in type 2 diabetes, a diagnosis of Cushing’s syndrome may be easily overlooked. Herein we describe resistant/refractory hypertension as a clinical clue to suspect Cushing’s syndrome in patients with diabetes.
