Pleural mesothelioma is a rare neoplasm originating from pleural mesothelial cell. Hypoglycemia associated with tumor is knowen to be a rare consequence of non-islet cell tumors. A patient having severe, episodic hypoglycemia was found to have a large mass occupying the left hemithorax. The hypoglycemia was resolved immediately after the surgical removal of the tumor. Histologic examination of the tumor revealed localized fibrous mesothelioma.

Solitary fibrous tumor of the pleura (SFTP) is a rare primary intrathoracic tumor that arises from mesenchymal tissue underlying the mesothelial layer of the pleura. It usually has an indolent clinical course. The hypoglycemia that accompanies SFTP was first described by Doege and Potter independently in 1930, hence the eponym Doege-Potter syndrome (DPS). The incidence of DPS is reported to be ~4%. In this report, we present a typical case of DPS that was cured through complete surgical resection.

A fibrous pseudotumor of the paratesticular region is rare, but one of the most common neoplasma of this area. It has also been called a nodular fibrous proliferation, pseudofibromatous periorchitis, benign fibrous paratesticular tumor, and fibrous mesothelioma (pseudofibroma). Complete surgical excision, by orchiectomy, appears to be curative. A case of a fibrous pseudotumor is reported and the clinical presentation and radiographic and histological findings described.

Localized fibrous mesothelioma of the liver is very rare benign tumor. It usually manifest large palpable hepatic mass in right upper quadrant area, and the prognosis is excellent by surgical resection. Contrast enhanced CT scan shows well defined hyperattenuating mass and celiac anglogram shows hypervascular mass. Recently we experienced 1 case of localized fibrous mesothelioma of the liver, and we report CT and anglographic findings of this tumor.

A right pleural mass was detected incidentally in a 52-year-old woman and chest computed tomography showed lobulated pleural mass. Thoracoscopic excision was performed. Histology showed solitary fibrous tumor with extensive cystic change. Solitary fibrous tumor with extensive cystic change is very rare and we treated this tumor successfully with video-assisted thoracic surgery.

We present a case of a 47-year-old woman with benign solitary fibrous tumor of the pleura originated in the diaphragm which was discovered incidentally on a chest radiograph. Chest radiograph, sonograph, computed tomographic scan and magnetic resonance image studies proved a well circumscribed and lobulated fibrous tumor of the pleura. During the subsequent right thoracotomy, the tumor was found to be encapsulated and consisted of firm mass. It was connected to the diaphragm with 5x4 cm area by pedicle. Most of the tumor was free of adhesion. It was excised completely together with attached diaphragm. The tumor measured 23.5x3.5x8.0 cm and the pathologic diagnosis was benign solitary fibrous tumor and the attached diaphragm was free of disease.

Solitary fibrous tumor(SFT) was previously named localized fibrous mesothelioma, and this is a rare mesenchymal neoplasm that usually shows benign behavior. It is the most commonly recognized tumor of the pleura. These tumors have been recently reported to be found in unexpected locations. To the best of our knowledge, there have been only 2 reports of SFT arising from the urinary bladder in Koreans. We review this third case of SFT that was misdiagnosed as bladder cancer. This tumor was removed from a 40-year-old man who had a history of lower urinary tract symptoms.

Solitary fibrous tumors (SFTs) most often involve the pleura and also may encompass the peritoneum and nonserosal sites. They occur as solitary encapsulated tumors and pursue a relatively benign clinical course. The usual criteria for malignancy are high cellularity, mitotic activity (more than 4 per 10 high-power fields), cellular pleomorphism, hemorrhage and necrosis as well as infiltrative growth. We report a case of malignant SFT of pleura who presented with an anterior mediastinal mass. Grossly, it was a 10x8x6.5 cm sized, encapsulated and well-demarcated, solid neoplasm with areas of extensive necrosis. Microscopically, parallel or haphazard arrangement of spindle cells with variable degrees of collagenous background were noted. Storiform fascicle formation, hemangiopericytoma-like pattern, and epithelioid cell clusters were often intermingled. Nodular areas with high cellularity and mitotic activity (> or =10/10 HPFs) were scattered throughout the neoplasm, however no definite cellular pleomorphism was encountered. Tumor cells were immunoreactive for vimentin and CD-34, which distinguished them from the mesothelial cells. Electron microscopically, they revealed fibroblastic and myofibroblastic differentiation.
