[A case of surgical resection of metastatic multiple lung pheochromocytoma with long-term survival]

A case of resection of metastatic multiple lung malignant pheochromocytoma is presented. Seven years before, total resection of the right adrenal gland and the right kidney was performed to remove a pheochromocytoma. During the post-surgical observation in the urology outpatient clinic, the blood noradrenalin concentration increased and multiple lung metastatic nidi were observed by chest X-ray. An excision was made to remove 3 wedge-shape metastatic nidi from both lungs. In the third year after the removal of the pulmonary metastatic nidi, a resection was again performed due to recurrence in the left retroperitoneal lymph node. Another recurrence was found in the S6 liver 1 year after the removal of the lymph node, and TAE and PEIT were conducted. When the recurrent metastatic nidi were found, the blood noradrenalin concentration was elevated, and it normalized after treatment. In this case, careful and long-term observation including monitoring the blood noradrenalin concentration in the outpatient clinic and positive surgical treatment proved effective. The patient is currently in good health without signs of recurrence 12 years after the removal of the primary adrenal nidus and 6 years after the removal of the pulmonary metastatic nidus.
