Abstract excerpt
Adult orbital xanthogranulomatous disease (AOXGD) is a spectrum of histiocytoses with four subtypes. Mitogen-activated protein kinase (MAPK) pathway mutations have been detected in various histiocytic neoplasms, little is known about this in AOXGD. Targeted regions of cancer- and histiocytosis-related genes were analyzed and immunohistochemical staining of phosphorylated ERK (pERK), cyclin D1 and PU.1 was...
