We have studied 27 oligodendrogliomas with a panel of antibodies (vimentin, GFAP, S-100 protein, myelin basic protein, CAM 5.2) and of lectins (WGA, Con A, PNA, RCA, DBA, SBA) to different glycoproteins. There were 16 well-differentiated tumours, including one gliofibrillary and 11 anaplastic oligodendrogliomas, three of which were gliofibrillary. Four(More)
Twenty unselected pituitary adenomas have been examined for proliferative indices (PIs), and anterior pituitary hormone expression. All but two of the tumours were non-functional with proliferative indices from less than 0.1 to 0.5%. Two tumours were null cell adenomas with PIs less than 0.1 and 0.2%. The PIs of the three recurrent tumours was less than(More)
We have studied formalin fixed, paraffin-wax embedded tissue from 35 medulloblastomas, collected over 23 years (27 non-desmoplastic and 8 desmoplastic) with KP1 and Mac387 two monoclonal anti-monocytes/macrophage (M/Ms) antibodies recommended for use on paraffin wax embedded tissue. In non-desmoplastic medulloblastomas, outside areas of necrosis, M/Ms were(More)
ABStrACt We report the case of a 2 month-old patient with a large, probably congenital, posterior fossa tumor. Hematoxylin and eosin staining (HE), reticulin and immunohistochemistry revealed a medulloblastoma with extensive nodularity, showing ganglioglial differentiation, high proliferative index in the primitive neuroectodermal tumor (PNET) area and low(More)
