Abstract

Abstract: Background: Primary small cell carcinomas (SCCs) are uncommon in extrapulmonary sites and account for only 2.5% to 5.0% of all SCCs. SCCs in the pyriform sinus are rare and there is little information regarding this disease, especially on therapeutics. Herein, we present a case of successfully treated SCC in the right pyriform sinus that occurred in a patient with small cell lung carcinoma (SCLC) that completely resolved 4 years prior. Methods: A 1.5 × 1.5-cm mass in the right pyriform sinus was detected on imaging studies in a 71-year-old male at a regular check-up visit after being in remission from SCLC. Results: Based on histologic examination and immunohistochemistry, the tumor in the right pyriform sinus was diagnosed as an extrapulmonary SCC. Chemo-radiotherapy was applied to the SCC of the pyriform sinus with a regimen of etoposide and cisplatin. The patient exhibited complete response to treatment and has been disease free for 11 months. Conclusion: This interesting case shows that chemotherapy with concurrent radiation may be an effective therapeutic modality for localized extrapulmonary SCC similar to localized SCLC, which is treated with concurrent chemo-radiotherapy as the standard therapeutic option.
