Figure 4 Gross findings of the resected colon. Gross examination of the resected specimen demonstrated diffuse inflammatory changes extending from the mid-transverse colon to the rectum. The mucosa showed extensive ulceration, edema, and areas of hemorrhage, with particularly severe involvement of the sigmoid colon, where near-necrotizing changes were observed. These findings are consistent with fulminant colitis.
