SUMMARY We report a case of solitary fibrous tumor (SFT) causing isolated hypoglossal nerve palsy. The neuroimaging appearance of the tumor was indistinguishable from that of schwannoma or meningioma. Immunohistochemical tests demonstrated strong reactivity for CD34 but an absence of staining for S100 and epithelial membrane antigen; this profile is indicative of an SFT. SFTs are mesenchymal tu...

Doege-Potter syndrome (DPS), a paraneoplastic syndrome, presents as a hypoinsulinemic hypoglycemia from the ectopic secretion of insulin-like growth factor II from a solitary fibrous tumor which may be intrapleural or extrapleural in origin. We report a case of severe hypoglycemia in a 70-year old female initially admitted for resection of left sided solitary fibrous tumor of pleura. Investigat...

Solitary fibrous tumours are rare mesenchymal soft tissue tumours arising from multiple sites in the body including the dura and the intracranial ventricles. These masses are grouped along with rare haemangiopericytomas which form about less than 0.4 % of all CNS tumours. Locally aggressive solitary fibrous tumours closely mimic other dural based tumours most likely meningiomas. We report a cas...

Background: Solitary fibrous tumor / hemangiopericytoma (SFT HPC) and fibroblastic types of meningioma have similarities that is difficult to distinguish based on histology. Immunohistochemistry STAT6 SSTR2A are definitive biomarkers in both tumors. Inversion-mediated fusions between two genes, NAB2 STAT6, were detected SFT HPC inducES proliferation cells. The somatostatin receptor (SSTR) 2 loc...

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...

Introduction: Fibrous dysplasias (FD) are a group of nonhereditary benign pathologies in which immature bone and fibrous stroma replace normal medullary bone as a result of abnormal differentiation of osteoblasts characterized by solitary (monostotic) or multi focal medullary (polyostotic) fibro osseous lesions. They contain mutated fibroblast cells and osteoblasts of varying functionality, whi...

The solitary fibrous tumor is a rare mesenchymal tumor, occurring preferentially in pleura, which has recently been described in extrathoracic sites. There are 6 reports on primary solitary fibrous tumor of bladder. They affect preferably men with mean age around 57 years, are usually asymptomatic and, despite eventually presenting morphologic features of malignancy, tumor resection is consider...

Solitary fibrous tumour is an uncommon soft tissue tumour initially described in the pleural cavity. In the past decade, it has been described in various extrapleural sites, including the abdomen. Traditionally regarded as benign, cases of histologically or clinically malignant solitary fibrous tumours are rare. This report describes such a case, although the patient is still disease free five ...

Solitary fibrous tumour (SFT) is one of the rare tumours which arise from visceral pleura. Klemperer and Rabin first described SFT as a distinct clinical entity among primary pleural tumoUrs in 1931. Approximately 820 cases have been reported in literature to date. The management of patients with SFT is complete resection of the tumour and follow up of the patient to detect any possible late re...

Nuchal-type fibroma is a rare, benign, fibrous, tumor-like proliferation characterized by dense hypocellular bundles of collagen, with sparsely scattered fibroblasts, interspersed fat tissue, and entrapped nerve fibers. It usually develops in the posterior neck as a solitary, firm, poorly circumscribed, subcutaneous mass. Herein, we report about a 32-year-old man who presented with a 6-year his...
