Leiomyoma is an extremely rare tumor in sinonasal area. The reason for this is due to minimal amount of the smooth muscle in the area. The origin of this tumor is not clear and its etiology has not been proven in the literature. A 58-year-old woman who experienced nasal obstruction and epiphora visited our clinic. A huge mass was noted in right nasal cavity originating from the lacrimal bone area. The authors conducted endoscopic sinus surgery and obtained the specimen. Immunochemistry showed leiomyoma in the nasal cavity, which expressed estrogen receptor. There was no progesterone receptor expressed. The authors describe a sinonasal leiomyoma with estrogen receptors, not ever reported in previous article.
