case_images: Abdominal ultrasound was negative for any acute abdominal process; abdominal radiography showed air-filled bowel distention without pneumatosis (Figure 1), and Meckel's scan revealed no evidence of ectopic gastric mucosa.
case_images: Colonoscopy view of the rectosigmoid junction. The figure demonstrates the colonoscopy view of the rectosigmoid junction with exudated, friable, erythematous mucosa (enclosed within circles pointed by arrows) and superficial erosions with a decreased vascular pattern

case_images: The colonoscopy with biopsy revealed an exudated, friable, erythematous mucosa at the rectosigmoid junction with superficial erosions and decreased vascular pattern (Figure 2) and erythematous and edematous mucosa at the transverse and descending colon (Figures 3, 4).

case_images: The EGD revealed linear erythematous mucosa in the gastric body and the first portion of the duodenum with swollen mucosa (Figures 5, 6).
case_images: Histopathology sample of the sigmoid colon. The figure shows the histopathologic sample of the sigmoid colon with evident mild acute colitis and acute neutrophilic crypt abscesses (indicated by arrows)

case_images: The microscopic findings of both studies revealed mild acute-on-chronic gastritis with crypt abscesses, mild acute-on-chronic duodenitis with mild villous blunting, mild acute-on-chronic colitis in the transverse and descending colon, and mild acute colitis with acute neutrophilic crypt abscesses in the sigmoid and rectum (Figure 7).
