Late recurrence of basaloid carcinoma initially treated as a small cell lung cancer

We present a patient originally treated with definitive chemoradiation therapy for small cell lung cancer (SCLC) of the right lower lobe. At 8 years post-therapy tumor recurred at the site of the original lesion without evidence of distant disease and was treated with lobectomy. Pathology demonstrated the tumor was a basaloid carcinoma (BC) rather than SCLC. She is alive and well at 2 years following her resection and 10 years following her definitive chemoradiation therapy.
