Fig. 3From: An enterogenous cyst with atypical pathological findings and chemical meningitisImmunohistochemistry of the cyst. a Epithelial membrane antigen immunostaining showed a positive reaction in the epithelium (original magnification 400); b carcinoembryonic antigen stained positive in the epithelium (original magnification 400); c neuron-specific enolase stained negative in the epithelium (original magnification 400); d vimentin immunostaining was negative in the epithelium (original magnification 400); e immunostaining for glial fibrillary acidic protein expression was negative in the epithelium (original magnification 400); f periodic acid–Schiff staining shows a positive reaction in the basement membrane (original magnification 400)Back to article page
