Schwannomas are uncommon benign neoplasms arising from the Schwann cells lining the nerve sheath. Retroperitoneal schwannomas are extremely rare constituting about 0.3‐3.2% of all retroperitoneal masses. Pancreatic schwannomas are obsolete and less than 50 cases reported until date in the literature. Ancient schwannomas is a histological variety in which there would be degenerative changes occu...

Ancient schwannoma is a rare variant of neural tumors though rarely seen in the thorax. The combination with coronary artery diseases is also rare. Here we describe a 66 year-old male who had undergone one-stage combined surgery for thoracic ancient schwannomas removal and coronary artery disease. The masses were, respectively, 13 cm in the middle mediastinum and 5 cm in diameter originating fr...

[Introduction and Purpose] Schwannoma, also referred to as neurilemoma and neurinoma, is a benign nerve sheath tumor which usually occur in the soft tissues of the head and neck and extremities. When the tumors are located in deep structures such as the mediastinum and the retroperitoneum, those tend to be larger masses with degenerative changes as ancient (degenerated) schwannoma. Because schw...

Background: There are four major lesions which may arise in the peripheral nerve, namely neuroma, schwannoma, neurofi broma and malignant peripheral nerve sheath tumor. Objective: In the present study we look into the spectrum of peripheral neural tumors including their age distribution site distribution and histopathology. Materials and methods: This is retrospective study conducted in the Dep...
