Frequent infection of cerebellar granule cell neurons by polyomavirus JC in progressive multifocal leukoencephalopathy.

abstract：:Lhermitte-Duclos disease (LDD) is a rare cerebellar tumor associated with Cowden disease (CD) and germline mutations in the PTEN gene. To further define these relationships, we reviewed clinical and pathologic findings in 31 LDD cases and analyzed the status of the PTEN pathway in 11 of them. We hypothesized that the ...
