Superficial leiomyosarcomas are rare soft tissue tumors, most frequently involving the lower extremity. Leiomyosarcomas which could be misdiagnosis or delayed are very rare in the head and neck region. In this report, a 46-year-old man with postauricular leiomyosarcoma was presented. The tumor was totally excised with 3 cm margins. Immunohistochemically, the specimen showed reactivity for smooth muscle actin, vimentin, and desmin. No complications developed in the postoperative period and the patient was free of recurrence at the 26 months follow-up. Immunohistopathological examination is essential for an accurate histological diagnosis. The ENT surgeon should pay attention to superficial leiomyosarcoma with its specific behavior and treatment while evaluating the lesions in the head and neck region.

Laryngeal leiomyosarcoma is rare. The authors report the case of a 48-year-old patient who presented with progressive hoarseness. This symptomatology was associated with a laryngeal tumour. Immunohistopathological study indicated a leiomyosarcoma. Acute dyspnoea resulted in an urgent tracheostomy, followed by total laryngectomy without neck dissection later. In the light of this observation and a literature review, histopathological characteristics, clinical aspects and therapeutic indications will be discussed for this localisation.

Leiomyosarcomas (LMSs) of the sinonasal tracts are rarely reported. We present a case of an LMS of the left inferior nasal concha, and discuss the management options with review of the literature. A 72-year-old female patient presented with epistaxis. Clinical examination and medical imaging showed a tumour arising from the left inferior nasal concha. An endoscopic resection was performed. Anatomopathological and immunohistochemical analyses revealed the tumour to be a grade 3 LMS with uncertain posterior margins. The patient was a Jehovah's Witness and refused more radical surgical resection due to religious beliefs; therefore, adjuvant conformal radiotherapy (60 Gy) was performed. LMS of the nasal cavity is a rare and locally aggressive tumour with a high tendency of recurrence, requiring radical surgical resection and long-term follow-up. The prognosis of a nasal cavity LMS is better than that of an LMS located in the paranasal sinuses.
