Background. Pleomorphic carcinoma (PMC) and mucoepidermoid carcinoma (MEC) of the lung are rare histological types of tumor. We herein describe a case of PMC and MEC occurring as synchronous multiple primary lung cancers. Case. A 74-year-old man was referred to our department because of a double mass in the left lower lobe. The examination of a transbronchial lung biopsy specimen confirmed the presence of non-small cell lung carcinoma (NSCLC). Both lesions were localized in the left lower lobe, and we performed thoracoscopic left lower lobectomy with lymph node dissection (2a-1). The pathological diagnoses were PMC (S6, pT3N0M0, Stage IIB) and MEC (S9, pT4N0M0, Stage IIIA). The postoperative course was uneventful. He left our hospital 2 weeks after surgery. Conclusion. We described a rare case of simultaneous PMC and MEC. This shows that multiple lung nodules can be synchronous multiple primary lung cancers as well as primary lung cancer and pulmonary metastases.
