Background:
Low-grade fibromyxoid sarcoma (LGFMS) is a rare malignant tumor. Moreover, only 3 cases of LGFMS originating from the nasal cavity and/or paranasal sinuses have been published so far.
Methods:
Two patients with histologically confirmed LGFMS of the maxillary sinus were primarily treated by open and endoscopic surgery. In one case adjuvant radiotherapy was indicated because of the uncertainty of the surgical margins.
Results:
Both surgeries were technically demanding and accompanied by significant bleeding from the tumors. Despite the extensive interventions there were no postoperative complications and no significant morbidity of the patients. There is no evidence of the disease 148 and 65 months after the treatment.
Conclusions:
Regardless of the excellent post-treatment results, based on our experience, preoperative embolisation of the tumor should be considered prior to the surgical resection.

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
