چکیده | ||
Leiomyosarcoma is a malignant tumor arising from smooth muscle cells accounting for 10-20% of soft tissue sarcomas and less than 2% are located in head and neck region. We report a case of leiomyosarcoma of maxilla in a 26-year-old female patient referred to Shahid-Beheshti University of Medical Sciences, Faculty of Dentistry. Patient complained of swelling of left side of the face from 5 months ago without a history of significant illness. Clinical examination showed asymmetric swelling of left side of the face with tenderness. The lesion in the left buccal vestibule was tender to the touch and contained erythematous mucosa with a firm tissue. Results of the neck computed tomography (CT) scan indicated mucosal thickening in the left maxillary sinus. In the preoperative magnetic resonance imaging (MRI), a mass with an estimated size of 4.7×3.1×3.0cm was found, extending from the posterior wall to the posterolateral wall of the left maxillary sinus, causing impression and remodeling of the sinus wall. Incisional biopsy was preformed and immunohistochemistry suggested leiomyosarcoma. Partial maxillectomy of the posterior maxillary walls was performed, using an intraoral incision and dissection from the maxillary vestibule up to the mandibular vestibule. The tumor was excised using frozen section. Pathological examination reported the lesion compatible with leiomyosarcoma, with all surgical margins free of tumor. Post-operative MRI showed no definite mass in the region. In conclusion, according to the present results, the clinical features of leiomyosarcoma of the maxilla are clear, and diagnosis is feasible. | ||
