Figure 1. Photomicrograph of case 1. Elastica-Masson staining shows a ruptured arteriole (arrow) with a mucosal defect, measuring up to 2 mm in diameter.

Figure 2. Photomicrographs of case 2. (A) Elastica-Masson staining exhibits submucosal tortuous arterioles (short arrows) and DL (long arrow). (B) High magnification indicates ruptured arteriole (arrow).

Figure 3. Photomicrograph of case 3. Elastica-Masson staining demonstrates ruptured arteriole (arrow), clarifying the cause of severe hemorrhage.
