Leiomyosarcoma (LMS) accounts for approximately 7% of all soft tissue sarcomas and occurs most frequently in the gastrointestinal tract and uterus. In the head and neck, however, LMS makes up only 2.3%. LMS of the nasal cavity and Para nasal sinuses are very rare and only about 20 cases of LMS of the nose and Para nasal sinuses have been reported in the literature. Initially, LMS should be treated by extensive surgical excision, long-term follow-up is essential due to the high rate of local recurrence. Radiotherapy and chemotherapy are insufficient therapeutic approaches. Frequency of recurrence and prognosis depend on the tumor site.
平滑肌肉瘤（LMS）约占所有软组织肉瘤的7%，最常发生于胃肠道和子宫。然而，在头颈部，LMS仅占2.3%。鼻腔和鼻窦的LMS非常罕见，文献中仅报道了约20例鼻腔和鼻窦LMS。起初，LMS应通过广泛手术切除进行治疗，由于局部复发率高，长期随访至关重要。放疗和化疗是不足的治疗方法。复发频率和预后取决于肿瘤部位。
