A solitary fibrous tumor is a relatively uncommon neoplasm that usually occurs in the pleura but occurs extremely rarely in the oral cavity. Reported herein is a rare case of a solitary fibrous tumor in the buccal cheek mucosa. A 50-year-old man visited the authors' hospital due to a buccal cheek mass whose size had increased. Excisional biopsy was done under local anesthesia. After the excisional biopsy, the patient was diagnosed to have a solitary fibrous tumor. In immunohistochemistry, the patient's solitary fibrous tumor was characterized by the expression of CD34 and CD99 on the neoplastic cells, and negativity for Bcl-2 and S-100. No recurrence or complication occurred for a period of 5 years. The growth of a primary solitary fibrous tumor in the buccal cheek mucosa is extremely rare and has been rarely reported in the South Korean medical literature. A solitary fibrous tumor must be distinguished from other spindle cell tumors. Presented herein is a case of primary solitary fibrous tumor in the buccal cheek mucosa. The relevant literature is briefly reviewed.

Solitary fibrous tumor is rare benign mesenchymal neoplasm. The spinal solitary fibrous tumor is extremely rare. The authors experienced a case of intramedullary solitary fibrous tumor of cervicothoracic spinal cord in a 48-year-old man with right lower extremity sensory disturbance. Spinal MRI showed intradural mass lesion in the level of C7-T1, the margin between the spinal cord and tumor was not clear on MRI. A Left unilateral laminectomy and mass removal was performed. Intra operative finding, the tumor boundary was unclear from spinal cord and it had intramedullary and extramedullary portion. After surgery, patient had good recovery and had uneventful prognosis. Follow up spinal MRI showed no recurrence of tumor.

A solitary fibrous tumor in the pleura has been reported occasionally, but extremely rare in themediastinum. The histogenesis of this tumor has been still in controverse, but recent studies paid attention to it a mesenchymal origin by the immunohistochemical and ultrastructural bases. A few cases, reported in the literature, suggest that the mediastinal solitary fibrous tumor occurs more commonly in adult and shows slightly higher incidence in women. Its aggressive behavior such as recurrence rate and distant metastasis, is more prominant than reported in solitary fibrous tumor of the pleura. No single histologic feature allows an assumption definite prognosis. Surgical resection of this tumor is usually curative although the recurrence or distant metastasis are reported in about half of the patients. This report is a case of solitary fibrous tumor in the mediastinum in a 16-year-old female patient.She underwent surgical resection and her postoperative result was satisfactory.

Solitary fibrous tumors are commonly arise in the pleura and less commonly in extrapleural sites. In head and neck area, solitary fibrous tumors can occur in nose, paranasal sinus, soft palate, epiglottis, thyroid, parotid and submandibular gland. To our knowledge, this is the 5th case of solitary fibrous tumor arising from the parotid gland in English literature. We report a case of solitary fibrous tumor occurred in the superficial lobe of right parotid gland which was successfully treated by superficial parotidectomy with preservation of the facial nerve.

Solitary fibrous tumor is a spindle cell neoplasm that can arise in any place of the body. Intracranial solitary fibrous tumors are rare. To our knowledge, only 57 cases with intracranial lesion have been reported. In Korea three cases have been reported. Our case was a 23-year-old woman who presented with morning headache. MRI showed a large intra-axial mass involving falx with typically isointense and heterogeneous strong enhancement on T1 weighted image in the right parieto-occipital region. Histologically the tumor showed spindle shaped cells within matrix with thick collagen deposition, hypercellularity, focal necrosis, and pleomorphism. Immunohistochemical study demonstrated diffuse positivity for CD34, Vimentin, Reticulin. In case of the intracranial tumors involving the meninges, we also should consider the solitary fibrous tumor with immunohistochemical staining for accurate diagnosis.

We report a rare case of a patient with meningeal solitary fibrous tumor. A 60-year-old woman presented with right leg monoparesis. Brain magnetic resonance imaging demonstrates a well enhancing huge mass, located in left parietal lobe. Cerebral angiography demonstrating increased vascularity in area of the tumor, which had feeder vessels extending from the internal carotid artery and external carotid artery. A presumptive diagnosis of meningioma or hemangiopericytoma was considered. At surgery, the consistency was firm and had destroyed the dura and skull. A gross total resection was performed. Immunohistochemically, tumor was strongly, and widely, positive for CD34 and vimentin. There was no staining for epithelial membrane antigen(EMA), S-100 protein, cytokeratin, and glial fibrillary acidic protein (GFAP). Differential diagnosis of intracranial solitary fibrous tumor includes fibroblastic meningioma, meningeal hemangiopericytoma, neurofibroma, and schwannoma.

Solitary fibrous tumor on the pleura is rare but should be included in the differential diagnosis on a peripheral pulmonary nodule. Cytologic features of solitary fibrous tumor of the pleura is not familar to the pathologist and may be misdiagnosed as malignancy. We report fine needle aspiration cytologic(FNAC) findings of a case of solitary fibrous tumor misdiagnosed as adenocarcinoma in a 48-year-old woman. The FNAC displayed a mixture of bland-looking spindle cells and clusters of epithelioid cells, which have hyperchromatic nuclei with prominent nucleoli. The helpful finding to distinguish It from other circumscribed benign and malignant lesions is the presence of fibromyxoid matrix admixed with blood vessels and thin collagen fibers. Familiarity with these features is essential to avoid misdiagnosis and overtreatment.

Solitary fibrous tumor is a rare spindle cell mesenchymal tumor entity, with either benign or malignant behavior that cannot be accurately predicted by histological findings. An intrapulmonary site of origin is even rarer. We report a case of a 51-year-old woman in whom an abnormal nodule in the lower right lung was detected during staging for sigmoid adenocarcinoma. The nodule was excised and pathological examination revealed an intrapulmonary solitary fibrous tumor.

Solitary fibous tumor of pleura is a rare and slow vowing neoplasm. The histogenesis of this tumor is thought as mesenchymal origin by immunohistochemical and ultrastructural bases. This case report is of a 69-year-old female who presented severe dyspnea and orthopnea with long-term history. Preoperative chest X-ray an chest CT revealed huge and hemithorax-occupying heterogenous mass and cardiomegaly. She underwent surgical resection and a 22 X 18 X 10 cm sized visceral pleural based mass was evacuated. Histologic findings of tumor showed patternless proliferation in a fibrocollagenous and well vasculized stroma. Immnohistochemical staining revealed strong positive in CD34, that are compatible with solitary fibrous tumor of pleura. The patient was discharged without any complications and no evidence of recurrence was found after 2 years.

Solitary fibrous tumor is an uncommon sybnesitgekuak mesenchymal neoplasm that arises primarily from the pleura. Extrapleural solitary fibrous tumors are rare. Solitary Fibrous tumors are often asymptomatic and discovered incidentally but may become symptomatic when vital structures are involved or they grow large. In general, solitary fibrous tumor is diagnosed on the basis of radiologic findings and its histologic features, with immunohistochemistry serving to support the diagnosis. Most solitary fibrous tumors pursue a benign course, and the single most important predictor of clinical outcome is the ability to excise the entire lesion. We experienced a case of intrapulmonary solitary tumor arising from the right lower lobe which was treated with wedge resection. We report this case of the patient.
