As degenerative properties are defined histologically, it can be wrongly interpreted as malignant. Case presentation: The case presented here is of a giant ancient schwannoma with a pelvic retroperitoneal location, which was mimicking an adnexal mass. Conclusion: In the rarely seen cases in the retroperitoneum, it may reach very large dimensions.</dc:description><dc:publisher>LIPPINCOTT WILLIAMS &amp; WILKINS</dc:publisher><dc:date>2016</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/17034</dc:identifier><dc:identifier>https://doi.org/10.1097/md.0000000000004240</dc:identifier><dc:identifier>0025-7974</dc:identifier><dc:language>en</dc:language><dc:relation>MEDICINE</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/17034</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
