  • 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.

  • Lipomas is one of the most common benign neoplasm in the body, but only rarely occurs in the oral cavity We report here a case of a 49-year-old female with a lipoma of palatine tonsil. Microscopical examination revealed a stromal neoplasm composed of mature fat with the presence of a few thin and anastomosing fibrous septa. The surface epithelium was of nonkeratinizing stratified squamous type. There was the dense fibrous connective tissue between mature fat and surface epithelium. The histopathologic findings and literature on tonsillar lipoma is reviewed.

  • 장막내의 고립성 섬유성 종양은 드물며 대부분 장측 또는 벽측 흉막에서 발생하지만 종격동, 심막, 복막, 폐실질 , 안과 그리고 뇌척수막에서도 발생하기도 한다. 이 종양은 다양성으로 인하여 진단하는데 어려움이 있으며, 특히 종격동이나 흉부 외의 장소에서 발생하는 경우에는 더욱 그러하다. 이 종양의 임상적 양상을 예측하기 어려우며 조직학적으로 양성의 소견을 보이면서, 임상적으로는 악성의 양상을 띠기도 한다. 악성의 임상양상을 보이는 경우는 약 13∼23% 정도로 보고되고 있다. 저자는 53세의 여자 환자에서 종격동의 고립성 섬유성 조양을 수술한 후, 4차례 재발한 드문 증례를 수술 치험하였기에, 문헌 고찰과 함께 보고하는 바이다.

  • Solitary fibrous tumor(SFT) is a spindle cell neoplasm that usually arises in the pleura. Its involvement of the meninges is rare but increasingly being reported. Our case was a 33-year-old man who presented with clonic seizure around the right mouth angle and sensory disturbance at the right hand. Radiological studies showed a large extra-axial, dural-based mass in the left fronto-parietal region, typically isointense with gray matter and heterogeneous strong enhancement on T1-weighted images. Histologically, the tumor was composed of spindle-shaped cells growing in fascicles within the collagenous matrix. Immunohistochemical staining demonstrated diffuse CD34 positivity. Awareness of this neoplasm is necessary to accurate diagnosis.

  • Solitary fibrous tumors of the pleura are rare, slow-growing benign neoplasm, originating from submesothelial Hbroblasts. Approximately 80% of solitary fibrous tumors of the pleura originate in . the visceral pleura and 20% in the parietal pleura. Many of these tumors are pedunculated, attached to the visceral pleura via a well-vasculariEed stalk, and in size from 1 to 36cm with a mean of 6cm. This case report is of a 48 year old woman who presented with dyspnea and right flank pain. Preoperative chest x-ray showed increased hazy density at right lower lung field, and CT scan showed huge heterogeneous mass which was located in right mid and lower thorax. She underwent surgical resec- tion and a lOX15X loom(2200gm weigh) sized large mass was excised. Final histologic diagnosis was solitary fibrous tumor of the plara. The patient was discharged without any complications postoperately.

  • Calcifying fibrous pseudotumors (CFP) are rare soft tissue tumors that have unique histopathologic features characterized by a dense hyalinized collagenous tissue interspersed with benign spindle cells, lymphoplasmacytic infiltrate, and psammomatous or dystrophic calcifications. We report here on a case of calcifying fibrous pseudotumors in the pleura and provide a literature review.

  • Calcifying fibrous pseudotumors are rare soft-tissue lesions pathologically characterized by hyalinized collagen, psam-momatous or dystrophic calcification, and lympho-plasmacyte infiltration. They are clinically benign with an extremely low rate of recurrence and complete surgical resection is known to be the treatment of choice. We performed the resection of a calcifying fibrous pseudotumors in the anterior mediastinum without complications.

  • Primary malignant fibrous histocytoma(MFH) of pleura is very rare. Upon microscopic examination, the tumor was characterized by storiform pattern of growth and intense, diffuse immunostaining for $\alpha$ l-antichymotripsin. We report a case of primary malignant pleural fibers histiocytoma with extension to lung, which was managed by complete excision of pleural mass and lobectomy with thoracoplasty.

  • Pleural mesothelioma is usually divided into two forms of localized and diffuse type. Localized pleural fibrous mesothelioma is uncommon mesodermal neoplasm, which may occurs in both sexes and at the age of 50 years. This type of mesothelioma is usually asymptomatic and detected on routine chest X-ray and made fibrous tissue and shows of collagen fibers microscopically. Most localized fibrous mesothelioma arises from the visceral pleura and is well encapsulated and pedunculated mass. CT findings included well delineated, often lobulated, non-calcified soft tissue masses in close relation to a pleural space, associated pleural thickening, and absence of chest wall invasion and a peripheral or fissure location. Three cases of localized pleural fibrous mesothelioma diagnosed by resectional surgery were reported with the review of literature.

  • 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.
