Benign Giant Retroperitoneal Neurilemmoma

Laparoscopic resection of retroperitoneal benign neurilemmoma

PURPOSE The aim of this study was to verify that laparoscopic resection for treating retroperitoneal benign neurilemmoma (NL) is expected to be favorable for complete resection of tumor with technical feasibility and safety. METHODS We retrospectively analyzed 47 operations for retroperitoneal neurogenic tumor at Yonsei University College of Medicine, Severance Hospital and Gangnam Severance ...

Retroperitoneal giant ancient schwannoma.

Ancient schwannoma is a rare variant of benign peripheral nerve sheath tumor, often morphologically mimicking malignancy. Retroperitoneum is an uncommon location. We describe one case of giant retroperitoneal ancient schwannoma. Literature concerning this variant is also reviewed. A 65 year old male presented with altered bowel habits. Imaging findings revealed a large heterogeneous mass in the...
