The recurrence rate of pheochromocytoma is said to be 6.17.1%, but only a few reports have been made on resection of local recurrence accompanied by malignant transformation and lymph node metastasis. We experienced a case of reccured malignant pheochromocytoma accompanied by extensive lymph node metastasis following a course of 8 years after an exision of the left adrenal gland for benign pheochromocytoma. The patient is a 50-year-old man who underwent an excision of the left adrenal gland for benign pheochromocytoma originating in the left adrenal gland on August 31, 1993. On May 30, 2001, a tumor in the left renal hilus was pointed out by CT and on July 5, uptake was observed at the same site by 131I-MIBG scintigraphy. Under the diagnosis of recurrence, he was admitted to our hospital on September 17. On CT, a large number of tumors 3.5×2.8cm in maximum diameter were seen in the retroperitoneum in the paraaortic region, andthe diagnosis of local recurrence accompanied by lymph node metastasis was made. On October 5, excisions of the tumors and retroperitoniel lymph node dissection were performed. Pathological findings of the resected specimens also indicated malignant pheochromocytoma accompanied by extensive lymph node metastasis. His clinical course is being followed with no signs of recurrence.
