Abstract
Soft tissue myxopapillary ependymoma is an extremely rare neoplasm classified as an ependymary tumour. We report a case of a soft tissue myxopapillary ependymoma in the sacrococcygeal region of an 18Â year-old male. Macroscopic examination of the surgical specimen showed an 8.3Â cm well-circumscribed nodular lesion. Histologically, it was seen to be a neoplastic epithelioid-like proliferation with papillae arranged around vascular structures, with occasional hyalinization. Immunohistochemistry revealed S100, GFAP and focal vimentin immunostaining but no CKAE1/AE3 expression. The differential diagnosis is discussed together with a review of the literature.
