Adenoid formation in medulloblastoma: a case report.
A medulloblastoma in a 3-year-old girl was described that showed epithelial features in the form of adenoid or acinar structure. Ultrastructurally, these adenoid formations exhibited glandular features and immunohistochemically stained for cytokeratin. Such structures were interpreted to be a distinct and hitherto unreported form of epithelial differentiation in medulloblastoma, similar to other epithelial features described in rare cases of high grade astrocytomas.
