[A case of synchronous double cancer in the same pulmonary lobe].
We have experienced a case of synchronous double cancer developing in the right lower lobe in a 75-year-old male. He was asymptomatic. His chest X-ray film showed two nodular shadows, one in the right proximal S8 and another in peripheral S9. The serum CEA level was elevated to 9.5 ng/ml. Bronchoscopic brush cytology revealed adenocarcinoma from the tumor in orifice of B8. He was therefore diagnosed preoperatively as having adenocarcinoma of the right S9 with metastasis to #12 hilar lymph node. Right lower lobectomy was performed. The final histological diagnosis was double primary lung cancer consisting of squamous cell carcinoma (S9) with rare mucoepidermoid carcinoma in the same lobe. His postoperative course was uneventful.
