background: ovarian fibroma is the most common benign solid tumor of the ovary, which is often difficult to diagnose preoperatively. the choice treatment for ovarian fibroma is surgical removal, but discussions for the operative approach, laparoscopic or open, in the literature seem to be scant. case presentation: we presented a unique clinical experience of laparoscopic approach to a case of 1...

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 CT sc...

BACKGROUND To better describe clinical T descriptors using solid tumor size (the maximum dimension of the solid component of the tumor) on high-resolution computed tomography (HRCT) and maximum standardized uptake value (SUVmax) on F-18-fluorodeoxyglucose positron emission tomography/CT (FDG-PET/CT). PATIENTS AND METHODS We examined 610 consecutive patients with clinical stage IA lung adenoca...

the brain is a rare site for metastasis in most extracranial pediatric solid tumors, including wilm’s tumor. outcome for these patients are generally dismal. very few cases have been reported to have good survival even after therapy. this paper reports a case of stage iv wilm’s tumor with lung metastases in a patient who developed a solitary brain metastasis five months after completion of chem...

Solid pseudopapillary tumors of the pancreas (SPT) are rare tumors of the pancreas with low malignancy potential and a very good prognostic outcome after surgery. The outcome after radical resection is favourable. A case of solid-pseudopapillary tumor (SPT) of the pancreas in a 20-year-old woman is presented. The patient underwent resection of the mass in the pancreatic head and pancreaticoduod...
