Abstract

Spindle cell carcinoma (SpCC) of the lung is extremely rare, with an incidence of less than 0.5% among all lung malignancies. Neuroendocrine tumors are frequently associated with secondary primary malignancies. Here, we report a case of metachronous SpCC that occurred after treatment of a primary carcinoid tumor of the lung. The SpCC mass was successfully removed by lobectomy. In immunohistochemical analyses, the tissues were positive for cytokeratin 7 and vimentin.
