The fibrous tumors of the pleura are rare primary tumors, accounting for 5% of malignant pleural neoplasms, which generally originate from sub-mesothelial mesenchymal tissue of the visceral pleura. These tumours generally exhibit clinical benign behavior although 12% of solitary fibrous tumors can be malignant and have worse outcomes. These tumors are considered "giant" when the lesion > 15 cm....

Giant cell tumor, excluding its prototype in bone, is usually a benign but local aggressive neoplasm originating from tendon sheath or soft tissue. Malignant behavior is uncommon. Visceral organ involvement including urinary bladder is rare. Giant cell tumors in visceral organs usually accompany epithelial tumors and the clinical behavior of giant cell tumor in urinary bladder is similar to its...

INTRODUCTION Von Hippel-Lindau disease (VHL) (OMIM193300) is an inherited multisystem cancer syndrome with visceral and central nervous system (CNS) manifestations.9 It is transmitted in an autosomal dominant fashion (chromosome 3p25) with greater than 90% penetrance by age 60 years.12 Visceral lesions consist of renal cell carcinomas and cysts, pancreatic islet cell tumors and cysts, pheochrom...

Type I Neurofibromatosis (NF1) is an autosomal-dominant inheritable disorder, with an incidence of 1:3,000, and a prevalence of 1:4,000 to 5,000. Pathogenesis is based on mutations of the NF1 gene, a tumor suppressor gene encoding a cytoplasmic protein named neurofibromin that controls cellular proliferation. Patients affected by NF1 typically present with cutaneous neurofibromas, cafè au lait ...

Granular cell tumors (GCTs) are soft tissue tumors, which are thought to be derived from Schwann cells. Although most GCTs are reported to arise in tongue and oral cavity (30-50%), they can appear on any anatomic sites, even visceral organs. Herein, we report 5 cases of GCTs on unusual anatomic locations, such as palm, arm, thigh, finger, and vulvar area. Complete surgical excision is preferred...

Granular cell tumors (GCTs) are rare and usually benign gastrointestinal tumors. Their most frequent symptoms are dysphagia and epigastric or retrosternal discomfort. We here report a case of esophageal GCT with continued symptoms of retrosternal discomfort, postprandial feeling of fullness, and early satiety despite complete thoracoscopic resection of the tumor. In contrast, all functional tes...

Objective:
 Lung cancer remains the leading cause of deaths worldwide. The surgical approach to locally advanced non-small cell lung (NSCLC) goes beyond classical and requires a multidisciplinary both preoperatively postoperatively. In addition tumor size, location T3 tumors affects extent surgery.
 Materials Methods:
 Patients who underwent resection for between March 2019 Octob...
