Tissue from gastro-esophageal junction, endoscopic biopsy ;
1. Esophageal mucosa, with 1) xanthoma, focal, 2) chronic active inflammation, 3) reactive basal cell hyperplasia, 4) parakeratosis, 5) some eosinophils infiltration ( 10 - 15 / 40 HPF)
2. Gastric mucosa, with 1) chronic inflammation, 2) regenerative glands
Note : The possibility of reflux esophagitis with focal xanthoma, reactive basal cell hyperplasia and parakeratosis is suggested. With treatment of inflammation, follow up biopsy is recommended.

Parakeratosis - Esophageal parakeratosis appears endoscopically as whitish, membranous, linear plaques that do not stain (turn brown) when sprayed with Lugol's solution. Biopsies reveal epithelial acanthosis, basal hyperplasia, and a dense, compact layer of parakeratosis, often featuring cytoplasmic eosinophilia and pyknotic nuclei, covered by an outer layer of nonnucleated squamous cells.

The clinical significance of esophageal parakeratosis is unclear; associations with esophageal and head and neck carcinoma have been reported, but the areas of parakeratosis themselves have not been shown to give rise to neoplasia. As an example, a prospective study of 400 patients with newly diagnosed squamous cell cancers of the head and neck found that close to 40 percent of patients had esophageal parakeratosis but none of the cancers clearly arose from such areas. Another report described an association with submucosal fibrosis of the oral cavity, particularly in smokers and those who chewed betel nuts. Because of the association with squamous cell cancer, we suggest careful evaluation of the esophagus and head and neck.
