Xanthelasma An esophageal xanthelasma is an extremely rare entity, literature is very scarce. Endoscopic features are a white and yellowish tumor with a smooth surface. Histology reveals typical foam cells. Etiology is unknown. A biopsy is compulsory to rule out early esophageal cancer.
Gastric xanthelasma are far more frequent.
Cardial polyp Esophageal polyps are pretty rare compared to colonic adenomas. They are reported to be linked to Barrett s Esophagus, but an adenoma- carcinoma sequence is also reported. Barrett s esophagus Barrett s mucosa is a metaplastic columnar epithelium, that has replaced the native squamous cells at the esophagocardial junction. It s thought to provide greater resistance to gastroesophageal reflux, which in turn is discussed to be causative. The left picture shows these dark red, finger- like epithelial islands amidst the normal, uninflammed, whitish, squamous epithelium.
