Introduction: Solitary fibrous tumors (SFTs) are exceedingly rare tumors arising from the submesothelial mesenchymal layer. Case Report: A case of a 60-year-old male with paranoid schizophrenia presented with acute gastric obstruction secondary to a large, obstructive, mobile mass. Surgical exploration revealed a 17x15x10.5 cm extraluminal, pedunculated mass originating from the lesser omentum ...

CONTEXT Solitary fibrous tumor is an uncommon spindle cell tumor which can occur in a variety of locations. Four cases of pancreatic solitary fibrous tumor have been reported in the literature. CASE REPORT We report the fifth case of pancreatic solitary fibrous tumor in a 78-year-old woman who presented with back pain and weight loss. Imaging studies were suggestive of an endocrine tumor. End...

Meningeal hemangiopericytomas (HPCs) are aggressive tumors characterized by a high rate of recurrence and delayed metastasis. Despite the malignant nature of these tumors, they often reach a large size with minor clinical presentations. To date, surgical treatment still remains the primary treatment of these tumors. HPC is a malignant tumor arising from pericapillary cells or Zimmerman pericyte...

Solitary fibrous tumors （SFTs） were reported in 1931 as derived from mesenchymal tissue. They occur mainly the pleura and peritoneum rarely oral maxillary regions. This report presents case of a 48-year-old woman with tumor left buccal mucosa. We suspected salivary gland or hemangioma. Excision was performed under general anesthesia. The lesion removed single mass. Histopathological immunohisto...

We report a case of solitary fibrous tumor (SFT) of the meninges. SFTs have been initially described in the pleura. SFTs show similar histological findings as in other locations. SFTs show a diffuse positive staining for vimentin and CD34. Meningeal SFTs have usually a favourable outcome. These tumors have to be essentially distinguished from hemangiopericytomas and fibrous meningiomas. Immunos...

INTRODUCTION Solitary fibrous tumors of the pleura (SFTP) are primary tumors arising from mesenchymal cells. Immunohistochemical studies have demonstrated that the origin of these tumors is mesenchymal rather than mesothelial. The aim of this study is to present our experience with diagnosing and treating patients with SFTP. MATERIAL AND METHODS We analyzed 18 patients treated at the Departme...
