A Case of Small Cell Carcinoma of the Maxillary Sinus with Distant Metastasis / 대한내과학회지

Primary small cell carcinoma of the paranasal sinuses is extremely rare. It is aggressively locally invasive, with high recurrence and metastatic rates. A combination of systemic chemotherapy and locoregional treatment, such as radiotherapy, is currently recommended based on the treatment of small cell carcinoma of lung. We report a case of small cell carcinoma originating from the maxillary sinus with distant metastasis at the time of diagnosis. The patient had a good initial therapeutic response to etoposide-cisplatin chemotherapy, but the cancer progressed after the sixth cycle of chemotherapy and the prognosis was poor.
