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.

고립성 섬유성 종양은 주로 흉막에서 발생하는 드문 종양으로 중피하 중간엽에서 기원하며 드물게 흉막 외에서 발생하기도 한다. 많은 경우에서 증상이 없이 우연히 발견되나 다른 중요 장기를 침범하거나 종양의 크기가 커질 경우 증상이 나타나기도 한다. 일반적으로 진단은 영상의학적 검사와 세침흡인을 통한 생검으로 하며 면역조직화학검사를 시행하여 더 정확히 판별할 수 있다 대부분의 경우 양성의 경과를 보이며 병변의 완전한 제거 여부가 가장 중요한 예후 인자가 된다고 알려져 있다. 저자들은 우하엽에 발생한 폐실질 내에 생긴 고립성 섬유성 종양을 채기 절제술로 치험하여 이에 보고하는 바이다

흉막에 발생한 고릴성 섬유종은 비교적 회귀한 질환으로 알려져 있으며, 대부분 장측 흉막에서 발생하고 벽측 홍막에서 발생되는 경우는 매우 드물다. 저자들은 48세 여자환자에서 우흉곽내 벽측 흉막에서 발생한 거대 고립성 섬유종 1례를 수술 치험하였다. 환자는 10개월전 부터 발생한 호흡곤란이 주증상이었고, 술전 흉부전산화 단층될영상 우측 폐실질을 주변으로 밀어내는 이종의 종괴형태를 보였다. 수술 소견상 종괴는 피낭에 싸여 있었고, 벽측 흉막에서 기 시하였다. 절제된 종괴의 크기는 20cmX15cmX11cm였고, 무게는 2200gm에 이르렀다. 환자는 합병증없이 퇴원하였으며 술후 6개월 간 추적 관찰하였으나 재발의 소견없이 양호한 상태를 보이고 있다.

Solitary fibrous tumors (SFT) are rare mesenchymal tumors that most commonly develop in the pleura; they rarely involve the diaphragm. MRI has not been widely used to evaluate SFTs of the thoracic cavity, though it may be highly useful in assessing local invasion, predicting malignant potential, and helping in the differential diagnosis. However, MRI findings of malignant SFTs of the diaphragmatic pleura have been described in only two cases. We report a rare case of a malignant solitary fibrous tumor of the diaphragmatic pleura in an 82-year-old man. We describe the clinical and characteristic imaging features, including computed tomography, conventional MRI, and diffusion-weighted imaging. Contrast-enhanced MRI is more accurate than is CT in identifying the origin of SFTs, predicting whether they ae benign or malignant, and assessing local invasion. This imaging modality proved helpful in deciding on the treatment strategy for these rare tumors.

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 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.

고립성 섬유종은 흉막에서 흔히 발생하는 양성 종양으로 알려져 있으나, 신체 어느 곳에서나 발생할 수 있고 10%-30%에서는 악성이다. 전형적으로, 고립성 섬유종은 단일성의 조영증강되는 종괴로 나타나지만, 척추 주위의 양측성 종괴로 나타나는 경우는 보고되어 있지 않다. 이 증례에서는, 등 통증과 만성 농흉의 병력이 있던 88세 남자 환자의 영상 검사에서 침습적인 양측성 척추 주위 종괴가 발견되었고, 만성 농흉과 연관된 흉부 악성 종양을 먼저 의심하였다. CT 유도하 이중구조 바늘 생검을 통해 진단된 양측성의 척추 주위 악성 고립성 섬유종의 증례를 보고한다.

A solitary fibrous tumor (SFT) is a rare neoplasm originated from the pleura, but they can occur in a variety of extrathoracic regions. Although many cases of primary SFT have been reported, there are extremely rare repots to date of a malignant SFT in the spine or skull. A 54-year-woman visited our hospital due to low back pain and both leg radiating pain. Several imaging studies including magnetic resonance imaging and computed tomography revealed expansive enhanced lesions in the occipital bone, T8, S1-2, and ilium, with neural tissue compression. We performed surgical resection of the tumor in each site, and postoperative radiosurgery and chemotherapy were performed. However, after six months, tumors were recurred and metastasized in multiple regions including whole spine and lung. The authors report here the first case of patient with malignant SFT of tandem lesions in the various bony structures, including skull, thoracic spine, and sacral spine, with a rapid recurrence and metastasis. Although malignant SFT is extremely rare, it should be considered in the differential diagnosis and carful follow-up is needed.

Localized or solitary fibrous tumor (SFT) of the pleura has been classified as a type of mesothelioma, arising from the submesothelial connective tissue cells. The preoperative diagnosis of the tumor at the cytologic or histologic level is very important for the proper handling of the lesion. This preoperative diagnosis is now possible by means of the advance in the transthoracic fine needle aspiration biopsy (FNA) techniques and in the very experience of the cytopathologists. We describe FNA cytologic feature of two cases of SFT arising from the pleura. Cytologic, histologic, immunohistochemical, and electron microscopic characteristics of pleural SFT are discussed. The tumor cells of SFT are spindle or oval in shape with a variable amount of cytoplasm. They are arranged in irregular trabeculae intimately associated with capillaries. A unique cytologic feature observed in this tumor is that thick, eosinophilic, amorphous collagen bundles are scattered between tumor cells.
