Sinosanal undifferentiated carcinoma with liver metastasis: Surgical management

Abstract

Background: Sinonasal undifferentiated carcinoma (SNUC) is a rare tumor with poor prognosis and high incidence of distant metastasis, even when a good loco-regional control is achieved. Case: We report the case of a 43-year-old female with SNUC diagnosis. Craniofacial resection with orbital exenteration and radiotherapy in tumor bed and lymph node chain was performed. After 10 months, SNUC hepatic relapse (sIII and sVIII) is diagnosed. We administered chemotherapy and then, surgical resection was carried out. After surgery, two new relapses were diagnosed, at 9 and 21 months where surgical management was performed in both cases. 56 months after SNUC diagnosis, the patient has no evidence of recurrence. Discussion: Recommended oncological clinical guidelines for distant metastases in SNUC are chemotherapy. Surgical management in oligometastatic disease in SNUC should be considered.
