Desmoplastic Medulloblastoma
Image Description
Desmoplastic medulloblastoma has a characteristic appearance on low power consisting of round pale nodules of tumor separated by zones of darker tumor cells. The pale nodules are composed uniform round to spindle shaped neuronal-appearing cells which are not as active mitotically as the surrounding darker tumor. They are present within a reticulin-poor fine fibrillary background. Desmoplastic medulloblastoma has a better prognosis than the classic form.
