title: Leiomyosarcoma of the ethmoidal cells.
abstract: Leiomyosarcomas of the paranasal sinuses are rare malignant tumors. A case of a 68-year-old female with leiomyosarcoma of the ethmoidal cells is presented. Since half a year she had a stuffed nose on both sides. Preoperatively, several attacks of epistaxis on the right side occurred. CT scans showed a tumor of the ethmoidal cells on the right side. The tumor was completely removed via a functional endoscopic endonasal approach and right sphenoethmoidectomy and maxillary sinus surgery. The operation was followed by a radiotherapy with 72 Gy. Up to 29 months after the operation local recurrence could not be observed. Endonasal tumor resection followed by radiotherapy in a case of leiomyosarcoma without invasion of orbit and skull base can allow tumor control.
