Solitary fibrous tumor is a rare spindle cell mesenchymal tumor entity, with either benign or malignant behavior that cannot be accurately predicted by histological findings. An intrapulmonary site of origin is even rarer. We report a case of a 51-year-old woman in whom an abnormal nodule in the lower right lung was detected during staging for sigmoid adenocarcinoma. The nodule was excised and ...

OBJECTIVES The solitary pulmonary nodule remains a common clinical problem. The essential question is whether the lesion is malignant or not. This discussion presents the clinical practice and looks at the problem. DESIGN Didactic. SETTING Academic tertiary-care hospital. PATIENTS Prospective thoracic database. INTERVENTIONS Minimally invasive technique. RESULTS The workup and treatme...

Solitary necrotic nodule of the liver is a rare benign lesion the histogenesis of which is still debated. We here report the case of a patient who underwent laparoscopic cholecystectomy for gallstones and who was accidentally found to have a solitary necrotic nodule of 2 cm in the fifth segment of the liver. On the basis of the histological findings, the hypothesis that different pathogenetic m...

introduction: solitary fibrous tumor is a rare, mesenchymal neoplasm that has been reported in numerous sites. occurrence in the parotid gland is exceedingly rare.   case report: a 53-year-old man with a 2 cm solitary fibrous tumor of the left parotid gland, that was observed clinically and operatively and thought to be a neoplasm arising from stensen's duct, is described. a pre-operative ...

BACKGROUND The minimal invasive investigation of solitary pulmonary nodules becomes increasingly important with the emergence of lung cancer screening. OBJECTIVES We report the results of the first utilization of a recently developed procedure in a bronchoscopy suite, which approaches solitary pulmonary nodules via a transparenchymal path. METHODS This study was a prospective, single-arm in...

OBJECTIVE To compare the probability of cancer in a solitary pulmonary nodule using standard criteria with Bayesian analysis and result of 2-[F-18] fluoro-2-deoxy-D-glucose-positron emission tomographic (FDG-PET) scan. SETTING A university hospital and a teaching Veteran Affairs Medical Center. METHODS Retrospective analysis of 52 patients who had undergone both CT scan of the chest and a F...
