A 62-year-old man was admitted with an abnormal shadow on chest X-ray film. He had an anamnesis of hypertension and was taking an antihypertensive agent. The irregular 45×25 mm shadow was recognized in the left upper lung field on chest X-ray and CT. Whole body CT examination revealed that the left adrenal gland had an internal heterogeneous shadow. Tests on hormone values in the blood and urine, abdominal MRI, and <SUP>123</SUP>I-MIBG scintiscaning yielded a diagnosis of pheochromocytoma preoperatively. Considering the preoperative and postoperative hemodynamics, surgery for pheochromocytoma was performed initially. Extirpation of tumor on the left adrenal gland method was performed on January 27, 1997. The neoplasm had developed outside the adrenal body and there was no infiltration to the adrenal body. One month after the first operation, on February 27, 1997, left upper lobectomy and mediastinal lymph node dissection (R2b) were performed. The pathologic diagnosis was poorly-differentiated adenocarcinoma, and the postoperative classification was p-t3nomo stage II B. The preoperative and postoperative hemodynamics were stable and were safely controlled. It was considered that, in lung cancer accompanied by pheochromocytoma, lobectomy can be conducted safely it surgery for pheochromocytoma is performed beforehand.
