Metastasising congenital subcutaneous sacrococcygeal ependymoma.

Abstract

A case of myxopapillary ependymoma located subcutaneously in sacrococcygeal area of a 18 months male child with metastasis to right inguinal lymph nodes is described; the tumour was present since birth. Histological examination of the tumour besides myxopapillary structures, also revealed an ependyma lined cystic space, resembling ventricular cavity. So far only two cases of congenital metastasising subcutaneous sacrococcygeal ependymoma have been described. However, the present case had a very aggressive post-operative biological behaviour.
