OBJECTIVE Varicella-zoster virus (VZV) infection may trigger the inflammatory cascade that characterizes giant cell arteritis (GCA). METHODS Formalin-fixed, paraffin-embedded GCA-positive temporal artery (TA) biopsies (50 sections/TA) including adjacent skeletal muscle and normal TAs obtained postmortem from subjects >50 years of age were examined by(More)
IMPORTANCE Giant cell arteritis (GCA) is the most common systemic vasculitis in elderly individuals. Diagnosis is confirmed by temporal artery (TA) biopsy, although biopsy results are often negative. Despite the use of corticosteroids, disease may progress. Identification of causal agents will improve outcomes. Biopsy-positive GCA is associated with TA(More)
The histiocytic disorders Langerhans cell histiocytosis (LCH) and Erdheim-Chester disease (ECD), can both present with multisystem involvement, with the central nervous system and the bone, skin, neuroendocrine, cardiac, respiratory, and gastrointestinal systems potentially affected. The 2 entities occasionally can be difficult to distinguish. Both rarely(More)
A case of a monodermal teratoma of the ovary composed solely of mature neuroglial elements is described. The cyst lining comprised ependymal cells surrounded by white matter which itself was resting on mesothelial cells. Astrocytes, oligodendrocytes, microglia and neurofilament-positive fibres were seen, but no neuron cell bodies were present.(More)
Identification of alterations in ALK gene and development of ALK-directed therapies have increased the need for accurate and efficient detection methodologies. To date, research has focused on the concordance between the two most commonly used technologies, fluorescent in situ hybridization (FISH) and immunohistochemistry (IHC). However, inter-test(More)
