Angiosarcoma of skull base in a 1-year-old child—A case report

Angiosarcoma is a rare tumour of endothelial cell origin whilst malignant skull base tumours are highly unusual in paediatric patients. This case reports an angiosarcoma involving the clivus and basi-sphenoid region of the skull base, in a 1-year-old boy. This tumour is extremely rare in childhood, particularly in this site. The histological features were consistent with a high-grade haemangioendothelioma, categorised as an angiosarcoma [1]. The characteristics of this rare malignancy and the challenges in its management are discussed. This is the youngest reported patient, to our knowledge, with an angiosarcoma of the skull base.
