Immunohistochemical staining patterns of canine meningiomas and correlation with published immunophenotypes.
This study examined immunohistochemical staining patterns for several meningioma variants involving either the brain or spinal cord of dogs. Formalin-fixed, paraffin-embedded tissue from 15 tumors was obtained. The selected tumor group included seven meningothelial, three transitional, two malignant (anaplastic), one myxoid, one papillary, and one osteomatous meningiomas. Tumors were evaluated ...
متن کاملImmunohistochemical expression of h-telomerase reverse transcriptase in canine and feline meningiomas
Telomere length maintenance is regarded as a fundamental step in tumorigenesis, as most human brain tumors, including meningiomas, stabilize the ends of their chromosomes using telomerase. This investigation represents an introduction to telomerase expression in canine and feline meningiomas. Twenty-five archived cases (14 dogs and 11 cats) were immunohistochemically tested for human-telomerase...
متن کاملImmunohistochemical staining for claudin-1 can help distinguish meningiomas from histologic mimics.
The histologic distinction between meningiomas and other tumors of the central nervous system occasionally can be difficult. Claudin-1 is a tight junction-associated protein recently shown to be expressed in anaplastic meningiomas. The purpose of this study was to determine whether immunohistochemical staining for claudin-1 could help distinguish meningiomas from histologic mimics, compared wit...
متن کاملImmunohistochemical evaluation of lymphocyte types infiltrate into the canine seminomas
BACKGROUNDS: Seminoma is frequently observed in human and canine testes especially in cryptorchids. Canine and human seminomas are typically associated with leukocytic infiltration. OBJECTIVES: We aimed to identify the type of lymphocytes that infiltrate to seminomas. METHODS: Tumor infiltrating lymphocytes were evaluated by immunohistological techniques in 5 dogs with diffuse seminoma. Routine...
متن کاملImmunohistochemical characterization of brain-invasive meningiomas.
Brain-invasive meningiomas have an adverse prognosis, so it is important to detect and correctly evaluate brain invasion by light microscopy. Furthermore, the underlying biological mechanisms responsible for brain-invasive growth are incompletely understood. The primary aim of this study was to identify immunohistochemical markers that could improve identification and evaluation of brain invasi...
