Retroperitoneal Ancient Schwannoma: A Case Report And Review Of Literature

Öz

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.
