Abstract

Ancient
Schwannomas are rare schwannoma variants originating from perineural Schwann
cells. These tumors are termed “ancient” based on the degenerative features they
indicated which is attributed to increasing age. They are accepted as benign,
slow growing tumors  mostly detected
incidentally. Some tumors may be mistakenly termed malignant if they
demonstrate nuclear atypia. Retroperitoneal schwannomas account for only 0.5%
to 5% of all cases and are extremely uncommon. As they are well encapsulated, recurrences
following complete surgical excision are uncommon.

We
present here a case of retroperitoneal ancient schwannoma and review this rare
entity under the guidence of recent literature.

Retroperitoneal Ancient Schwannom: Olgu Sunumu

Abstract

Ancient
Schwannom perinöral schwan hücrelerinden gelişen nadir bir schwannom çeşididir.  Bu tümörler dejeneratif özelliklerine dayanarak 'ancient' olarak ifade edilir. Benign kabul edilip yavaş büyüme özelliği gösterdiklerinden çoğunlukla insidental olarak saptanır. Nükleer atipi göstermeleri halinde kimi zaman malign gibi değerlendirilebilirler. Retroperitoneal yerleşimli schwannomlar tüm olguların % 0.5 - 5 'ini oluşturur. Bu makalede bir retroperitoneal ancient schwannom olgusu sunulmuş ve literatür eşliğinde tartışılmıştır.
