Combined large cell neuroendocrine carcinoma.
We report a case of combined large cell neuroendocrine carcinoma. A 78-year-old man with vertigo was referred to our hospital where chest X-ray revealed a tumor shadow in the right lung. A transbronchial lung biopsy specimen verified a diagnosis of non-small cell lung carcinoma (cT1N0M0). Right lower lobectomy with mediastinal lymph node dissection (#7, 8, 9) was performed. A postoperative histological diagnosis was combined large cell neuroendocrine carcinoma of a component of squamous cell carcinoma [pT4 (pm) N2M0]. The patient received concurrent chemoradiotherapy due to upper mediastinal lymph node metastasis 4 months after surgery. The chemoradiotherapy well responded and the patient remains well 9 months after surgery.
