Primary nasal clear cell carcinoma:a case report and literature review / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To explore the clinical and pathological characteristics of the primary nasal-sinonasal clear cell carcinoma, and then summarize the diagnosis and treatment.@*METHOD@#The clinical, imaging and pathological data were analyzed in one patient with primary nasal-sinonasal clear cell carcinoma. The domestic and foreign related literatures from 1992 were reviewed and summarized.@*RESULT@#In 12 cases of primary nasal-sinonasal clear cell carcinoma, 8 cases (66.7%) mainly presented with nasal bleeding, 4 cases (33.3%) with destroyed bone. CT scan showed the sheet shadow similar to soft tissue density in the nasal cavity and paranasal sinuses. Three cases (25.0%) were only treated by surgical resection, 7 cases (58.3%) were treated by surgical resection combined with radiotherapy and chemotherapy, 2 cases (16.7%) were treated by radiotherapy alone. During the 6 months to 10 years follow up, only one patient died of lung metastasis.@*CONCLUSION@#Primary nasal-sinonasal clear cell carcinoma is rare. Nasal bleeding is commonly one of the early symptoms. It must be differentiated from metastatic clear cell carcinoma and a variety of salivary gland tumors with clear cell in pathology. Surgery combined with radiotherapy and chemotherapy is effective treatment. Short-term prognosis is good. Endoscopic surgery can be used to the tumor with a base limited in the nasal cavity and sinuses in early time. The regular check after surgery should be taken to the patients every half a year.
