Juvenile Nasopharyngeal Fibroma (J.N.A) is a rare nasopharyngeal tumor that affects male adolescents; it is a benign but locally aggressive vascular tumor due to invasion of adjacent structures. The symptomatology is not very specific; but predominated by epistaxis. His treatment is essentially surgery; however, the use of other therapeutic means: radiotherapy, interventional arteriography, chemotherapy and hormone therapy are of value in the case of locally unresectable advanced tumors. Through our observation of a case of nasopharyngeal fibroma, we discuss the clinical, radiological and histological aspects as well as the therapeutic management of these tumors.
