Adenoid cystic carcinoma of the nasal cavity is a rare malignan cy. It is a slowly progressive disease, characterized by local re currences and distant metastases and requires early and adequate management. We report a case of Adenoid cystic carcinoma of the nasal fossa and will discuss the diagnostic and therapeutic charac teristics in the highlight of a review of the literature

1.1. Rationale: The epithelioid trophoblastic tumour (ETT) is a very rare type of gestational trophoblast neoplasm (GTN), ac counting for 0.5%-2.0% of all GTNs. With their unusual ability to simulate an invasive epithelioid neoplasm, ETTs frequently pose a diagnostic challenge, especially when they involve the uterine cervix. ETTsare caused by the malignant transformation of inter mediate trophoblasts, so they are not sensitive to chemotherapy. Surgery is the primary treatment.
