Stains / Test Description
The morphology of MRTs can present challenges in differential diagnosis. The overall survival of MRTs relative to its potential mimics [medulloblastoma, supratentorial primitive neuroectodermal tumors (sPNETs)] is quite low, and thus differentiation from these other tumors is desirable. Lack of nuclear labeling by anti-INI-1 is characteristic of MRT. The majority of medulloblastomas and sPNETs are labeled by anti-INI-1. MRTs also originate from the kidney and soft tissues.1-3
