Leiomyoma of the nasal septum

Leiomyoma is a benign myogenic tumor that may develop wherever smooth muscle is present. It occurs commonly in the uterus, skin, and gastrointestinal tract and is rare within the nasal cavity. Only three of twenty-four reported cases of sinonasal leiomyoma have been found to originate from the nasal septum. Treatment of choice for these neoplasms is surgical excision. We present two cases of nasal septal leiomyoma. Unique features discussed include recurrence of one neoplasm and the technique used to endoscopically repair a cerebrospinal fluid leak resulting from resection of the neoplasm.
