Medulloblastoma metastasizing to a breast fibroadenoma: A case report

Abstract

The extracranial spread of primary intercranial tumours is infrequent, occurring most commonly with medulloblastoma. The spread of one malignant tumour to a second tumour, benign or malignant, is also very rare. This case appears to be unique, in that a primary malignant cerebral tumour metastasized to a benign extracranial tumour.
