Adrenocorticotrophic hormone secreting pheochromocytoma.
We report a rare case of pheochromocytoma of the adrenal gland presenting as Cushing syndrome. A 30 year old woman presented with pain in the left loin and classical Cushingoid features. She was a diabetic and hypertensive on treatment. Magnetic resonance imaging of the abdomen revealed a 3.5×3 cm mass in the left adrenal gland. Urine analysis revealed an elevated 24 hr urinary cortisol level. Clinical diagnosis was Cushing syndrome due to functioning left adrenal tumor, and hence left adrenalectomy was performed laparoscopically. Histopathological examination revealed adrenal pheochromocytoma. Immunohistochemical analysis of the tumor was positive for adrenocorticotrophic hormone and chromogranin.
