Leiomyosarcoma (LMS) is a rare soft-tissue cancer of the head and neck, accounting for 1% to 2% of nasal cavity and paranasal sinus tumors. It is more commonly found in the gastrointestinal or genitourinary tract. Leiomyosarcoma of the head and neck is associated with a history of radiation therapy, retinoblastoma, chemotherapy, human immunodeficiency virus, or AIDS. We describe what we believe is the first case of an LMS of the sphenoid sinus in the English-language literature and include a review of the literature on LMS of the paranasal sinuses, which identified approximately 50 cases of primary sinonasal LMS.
