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.

Endometriosis of a surgical scar is rare and occurs mainly when a hysterectomy or Cesarean section was performed. We describe a 54-year-old woman with a large suprapubic mass as a definite case of a endomerioid carcinoma developing within the scar endometriosis following Cesarean section. Scar endometriosis, as well as endometriosis at other sites, can turn malignant. Endometrioid carcinoma is the most common histological pattern of malignant tumor arising in endometriosis. But clear cell carcinoma is very unusual. A case of primary clear cell carcinoma in endometriosis of a Cesarean section scar is described. To the best of our knowledge, this is the first documented case of endomerioid carcinoma developing within the scar endometriosis in Korea.
