A Case of Basaloid Carcinoma of the Lung

Abstract

Background. Basaloid carcinoma (BC) of the lung is rare and prognosis is poor. It is histologically classified on a variant of large cell carcinoma. We report a case of BC. Case. A 67-year-old man presented with a 10-mm tumor located in the left upper lobe. The preoperative cytological diagnosis was large cell neuroendocrine carcinoma. We performed left upper lobectomy and node dissection. The case was diagnosed as BC of the lung by histopathological findings. Conclusion. BC is considered to have poor prognosis, and careful follow-up is necessary.
