Solitary fibrous tumor (SFT), which was initially believed to be a subtype of mesothelioma, has been reported to occur outside the pleura. In the head and neck region, it primarily manifests in the oral or nasal cavity, with rare occurrences in the facial region. A 40-year-old woman visited our hospital with a mass on her chin. Prior to surgery, involuntary movement was observed in the ipsilateral corner of the mouth upon palpation of the mass. Special care was taken during the surgical procedure to avoid damaging the facial nerve. The mass was excised, and histological examination and immunohistochemical analysis confirmed the diagnosis of an SFT. Here, we present the first reported case of an SFT diagnosed in a jaw mass in Korea. The objective of this study was to highlight the importance of the diagnostic accuracy of SFTs in lower jaw masses.

The authors reviewed 114 cases of malignant major and minor salivary gland tumors at Presbyterian Medical Center seen from February, 1963 to December, 1983. The results were obtained as follows; 1) Overall male and female sex ratio was 2:1. The peak age of patients with major and minor salivary gland tumor were both 5 th decade. 2) The ratio of benign and malignant tumor was 83:114. The incidence of malignancy in each group was 52% in parotid (50 patients), 75% in minor salivary gland (45 patients), 49% in submaxillary gland(18 patients) and 25% in sublingual gland (1 patient). 3) The incidence according to the anatomic primary site for minor salivary cancers was 10 cases in the nasal cavity, each 8 in the palate and the maxillary antrum, 7 in the tongue, 5 in the gum, 3 in the larynx and 2 in the buccal mucosa. 4) Adenoid cystic carcinoma was the most common cancer of minor salivary gland and malignant mixed tumor was the most common in major salivary glands, each comprising 34 cases (76%) of minor and 19 cases (28%) of major salivary gland tumors. 5) The incidence of cervical lymph node metastasis was 50% in the submaxillary gland cancers, 44% in the parotid gland cancers and 21% in malignant tumors of minor salivary glands. The highest incidence of lymph node metastasis according to histopathological classification was formed in high grade of mucoepidermoid (67%). 6) Nerve invasion was common in mucoepidermoid carcinoma. According to anatomic site, nerve invasion occurred most often in adenoid cystic carcinoma of the submaxillary gland (44%). 7) The lung was the commonest site for distant metastasis comprising 12 cases among 26 cases in which distant spread occurred. 8) The recurrence rate was 50% for major salivary gland cancer and 52% in cancer of the minor salivary gland. In accordance with pathological classification, adenocarcinoma most frequently recurred after excision. This being seen in 88% of patients undergoing definitive therapy. 9) The determinate 5 year survival rate was 78% in major salivary gland tumors, but 69% in minor salivary gland tumors.

Meningioma originates from arachnoid cap cells and is the second most common intracranial tumor; however, it can also be found in an extracranial location. A very rare primary extracranial meningioma without the presence of an intracranial component has also been reported. Primary extracranial meningiomas have been found in the skin, scalp, middle ear, and nasal cavity. A computerized tomography or magnetic resonance imaging scan is necessary to determine the presence or absence of an intracranial meningioma, and a biopsy is essential for diagnosis. We report a case of primary extracranial meningioma located in the forehead skin of a 51-year-old male.

Sinonasal undifferentiated carcinoma (SNUC) is an extremely rare, highly aggressive malignancy of the nasal cavity and paranasal sinuses. Patients with SNUC usually being asymptomatic until the tumor has extensively progressed therefore frequently present with invasion of the orbit or cranial vault. Most case series of SNUC report very poor prognosis despite aggressive multimodality therapy. We recently experienced a 78-year-old male patient diagnosed as SNUC occurred from the left sphenoid sinus with invasion to the cavernous sinus and orbital content, which was treated intranasal endoscopic debulking surgery combined with curative radiation therapy successfully, and report this case with a review of literature.

Oronasal bleeding that continues despite oronasal packs or recurs after removal of the oronasal packs is referred to as intractable oronasal bleeding, which is refractory to conventional treatments. Severe craniofacial injury or tumor in the nasal or paranasal cavity may cause intractable oronasal bleeding. These intractable cases are subsequently treated with surgical ligation or endovascular embolization of the bleeding arteries. While endovascular embolization has several merits compared to surgical ligation, the procedure needs attention because severe complications such as visual disturbance or cerebral infarction can occur. Therefore, comprehensive understanding of the head and neck vascular anatomy is essential for a more effective and safer endovascular treatment of intractable oronasal bleeding.

Sinonasal Undifferentiated Carcinoma (SNUC) is a very rare, highly aggressive malignant tumor of the nasal cavity and paranasal sinuses. SNUC tends to present with advanced-stage disease, often with intracranial invasion. It requires an aggressive multimodality therapy that includes surgical resection. A cure rate of less than 20% is generally reported in the literature, with most patients dying within 1 year of onset of the disease. Three patients diagnosed as SNUC were treated at the Yeungnam University Medical Center between the years 2000 and 2003 were analyzed retrospectively. All patients presented with the disease very advanced. The three cases were given chemotherapy or chemotherapy with radiotherapy. Two patients died of the disease, surviving only 6 and 11 months following treatment, respectively. We did a follow-up on just the one remaining case with incomplete controlled disease for 27 months. The overall prognosis of SNUC is very poor. We consider that more intensive multimodality therapies are recommended for all patients with SNUC.

Soft tissue sarcoma of the head and neck is not frequent neoplasm, accounting for less than 1% of all malignant neoplasm in the region. The histological varieties include osteogenic sarcoma, malignant fibrous histiocytoma, rhabdomyosarcoma, fibrosarcoma, tenosynovial sarcoma, angiosarcoma and chondrosarcoma. Rhabdomyosarcomas of the head and neck usually occur in children under the age of 10 years (over 70%) and rarely develop in adults over the age of 20 years. The prevalent sites of involvement include the orbit, nasal cavity, external ear, paranasal sinus and soft tissue of mouth and the primary location of tumor is considered to be one of the important prognostic factors. Before the 1960s, when surgical resection was the only method of treatment, the 5-year survival rate was less than 20%, but recently it has been greatly improved by the multimodality treatment, combining surgery with chemotherapy and radiation therapy. Here we treated a rhabdomyosarcoma woman with three cycles of high dose chemotherapy followed by radiation therapy. After the, completion of preoperative treatments, successful result of more than partial response was achieved. Three months later total maxillectomy and radical neck dissection was performed. There was no evidence of tumor infiltration in the resected tumor and regional lymphnodes but metastasized tumor cells in cervical lymphnodes were detected. Tumor cell infiltration was also found on the bone marrow biopsy to evaluate the pancytopenia which occurred during postoperative recovery. Two months later she died of secondary bone marrow failure. We think that this multimodality treatment combining pre-operative chemotherapy, radiotherapy and surgery might play an important role in curative resection and eyeball preservation in patients with rhabdomyosarcoma involving the eyeball.
