Neurofibroma arises in the Schwann cells or in the peripheral tissue of nerve sheaths. It usually occurs as a part of neurofibromatosis and occasionally as a solitary lesion, but rarely occurs in the nasal cavity or in the paranasal sinuses. Organized hematoma is a rare solitary benign lesion with locally destructive behavior. It can be formed by the organizing process of hematoma in the unaerated environment. Organized hematoma by intratumoral bleeding has not yet been reported in the sinonasal tract. We recently experienced a case of neurofibroma accompanied by an organized hematoma extending into the maxillary sinus. It was treated successfully by a combination of endoscopic and Caldwell-Luc approach. It was finally confirmed as a neurofibroma containing an organized hematoma by histological and immunohistochemical examinations. Therefore, we present this rare case with a review of the literature.
