Leiomyosarcoma is an uncommon malignant soft tissue tumour originating from smooth muscle cells. It generally occurs in the female genital tract, especially in the uterus, gastrointestinal tract, retroperitoneum and rarely in the head and neck. Here we report a case of leiomyosarcoma in a 24-year-old man with a 6-month history of toothache and extraction of three right upper molar teeth, that was complicated by fistula tract formation and facial swelling. Imaging studies demonstrated tumoural lesions involving the right maxillary sinus, nasal cavity, hard palate and orbit. The histopathological and immunohistochemical studies confirmed that it was leiomyosarcoma.
