Congenital infantile fibrosarcoma mimicking sacrococcygeal teratoma in a Ghanaian infant: A case report and review of the literature

Abstract

Congenital infantile fibrosarcoma (CIFS) is a rare tumour of childhood accounting for less than 1% of malignant tumours in children. Reports from sub-Saharan Africa are particularly rare and the occurrence in the sacral region mimicking a sacrococcygeal teratoma has not been reported in Africa to the best of our knowledge. The poor predilection of the tumour for distant metastases may contribute to its above average prognosis, but the rarity of systemic antenatal detection of congenital conditions in most parts of Africa may mitigate this good fortune. We report the very rare case of a 9-month-old female infant who presented with a progressively increasing painless sacral mass from birth which was thought to be a sacrococcygeal teratoma clinically but histopathological assessment revealed a CIFS.
