title: Primary malignant lymphoma combined with clinically "silent" pheochromocytoma in the same adrenal gland.
abstract: An increased number of adrenal tumors are now diagnosed due to the increased number of abdominal CT scans being performed. We present the first case of malignant lymphoma combined with clinically "silent" pheochromocytoma in the same adrenal gland. An abdominal CT scan demonstrates unilateral adrenal lesion which suggests pheochromocytoma or adrenal carcinoma. Laboratory examinations revealed a slight increase of 24-h urine vanillylmandelic acid and 24-h urinary methanephrine excretion. Histological examination revealed two intermingled tumor cell proliferations-diffuse B cell lymphoma and pheochromocytoma.Unexpected coexistence of catecholamine-producing tumor with the other adrenal lesion can lead to serious complications of diagnosis and treatment. The adequate preparation for surgery can protect patient from threatening catecholamine crisis.
