: Histological samples of human ESCC and esophageal tissue samples of patients with esophagitis were collected, between July and December 2015, from patients who underwent endoscopic procedures with biopsies and/or surgical resection at Pontificia Universidade Católica do Rio Grande do Sul (PUCRS, Porto Alegre, Brazil). The diagnosis was reviewed by two certified pathologists with at least 20-year experience in surgical pathology. Samples were obtained in accordance with approved ethical standards of the Institutional Research Ethics Committee (CAAE 4969 6115.0.0000.5336).
