A CASE OF FAMILIAL PHEOCHROMOCYTOMA RECURRENT AFTER 23 YEARS

A 57-year-old man with a history of left adrenalectomy for pheochromocytoma 23 years ago was admitted to our hospital. Examinations revealed a hypervascular tumor in the left renal hilar regin. With the diagnosis of recurrent pheochromocytoma, after the blood pressure was stabilized, a tumor weighing 16g and measuring 5×3.5×3.5cm was resected. The blood catecholamine did not decrease postoperatively. An abdominal CT scan and an aortography showed a remaining tumor adjacent to the arta. The patient was reoperated and a tumor located dorsal to the left renal vein was removed. This tomor weighed 7g and measured 3×2.3×2cm. Hitologically the two tumors were benign pheochromocytoma. Around the same time the patient's eldest son underwent surgery for the same disease. This reported case is the 19th case as familial pheochromocytoma and the 10th case as recurrent pheochromocytoma in Japan as far as the authors confirm. It should be emphasized multiple lesions could be suspected in treating recurrent pheochromocytoma.
