The relative positive cell density and intensity of immunostaining is indicated as follows: 0, no detected staining; +/−, positive staining in less than 10% of cells; +, scattered or low intensity; ++, moderate intensity in many cells; +++, high intensity in most or all cells. F, Female; M, male; MBEN, medulloblastoma extensive nodularity; ND, not done.
