Endoscopic classification of verrucous gastritis (VG) assessed with indigo carmine dye spray. VG is classified into the VG-negative group (fewer than five verrucous lesions) (A) and the VG-positive group (at least five verrucous lesions). The VG-positive group is subclassified into the classical type (verrucous lesions were localized in the terminal antrum) (B) and the numerous type (number and/or distribution of verrucous lesions were large) (C).
