The primary tumors of the pleura are usually examined under two headings: diffuse and localized tumors. In the localized form, there is no relationship with asbestosis (1). Localized fibrous tumors were previously known by names such as benign mesothelioma, submesothelial fibroma and localized fibrous mesothelioma. Today, they are usually referred as localized fibrous tumors (2). These tumors c...

Calcifying fibrous tumor (CFT) is a rare mesenchymal tumor, affecting children and young adults with a predilection for the soft tissue and the abdominal cavity. CFT of the tubular gastrointestinal tract is very rare with less than 20 cases of gastric CFTs reported in English literature. This benign hypocellular fibrosclerotic calcifying lesion can resemble other spindle cell tumors particularl...

BACKGROUND Solitary fibrous tumors are rare tumors of mesenchymal origins, most commonly seen arising from the pleural lining of the lungs. These are generally benign tumors, which in rare cases have been identified to be associated with multiple para-neoplastic syndromes. CASE REPORT This is a case of a solitary fibrous tumor of the pleura in a 49 year old female which was found to be associ...

Background: Solitary fibrous tumor (SFT) is a mesenchymal tumor which is most commonly seen in the pleura; however it can be seen in other organs such as the meninge, gastrointestinal tract, soft tissue, bone, and skin. SFT should be differentiated from other mesenchymal tumors in these organs. Immunohistochemistry plays a pivotal role for the histopathologic diagnosis...

Intracranial solitary fibrous tumors are rare, and intraventricular fibrous tumors are even more unusual. We report a case of solitary fibrous tumor in the region of trigone and body of the left lateral ventricle and discuss the clinical presentation, CT characteristics, and histopathologic features with 1-year follow-up. We speculate that the tumor arose from the perivascular connective tissue...

The overexpression of Twist and Slug and subsequent down-regulation of E-cadherin facilitate the acquirement of invasive growth properties in cancer cells. It is unclear which of these molecules are expressed in mesenchymal tumors in the central nervous system. Here, we investigated 10 cases each of hemangiopericytoma, solitary fibrous tumor, meningothelial, fibrous, angiomatous, and atypical m...

•Solitary fibrous tumors are typically indolent tumors of the pleura.•Primary origin in the female reproductive organs is rare, as are aggressive forms.•We report a case of a vulvar solitary fibrous tumor, notable for extensive spinal metastasis.

conclusions primary mesenteric tumors are rare and mostly benign tumors. complete surgical excision is necessary for all tumors and follow-up is necessary after surgery for malignant fibrous histiocytoma due to recurrence. case presentation we encountered four cases of different primary mesenteric neoplasms that were operated at the gazi yasargil teaching and research hospital, department of ge...
