Lymphangiomas are enough rare benign congenital tumors of the lymphatic vessels, frequently encountered during childhood. They are found in the head and neck region, the isolated localization in the nasopharynx is very rare. We present the case of 54-year-old man admitted in the Department of Ear, Nose and Throat (ENT), Emergency University Hospital of Bucharest, Romania, with a nasopharynx tumor certificated by computed tomography (CT) scan with significant bleeding to a previous incisional biopsy temptation rising angiofibroma suspicion. We performed the radical surgical excision of mass by transoral approach. Postoperative bleeding imposed angiography with right internal maxillary artery embolization. Histopathological evaluation showed the diagnosis of lymphangioma. After three years, the patient is without recurrence.
