A 9-year-old boy presents with abdominal pain that started nearly 6 hours ago. The pain is located in the periumbilical area and radiates to the right lower quadrant. There was no vomiting or passage of stool since the onset of pain. The patient reports that he passed stools with blood several times during the past month. The vital signs include: blood pressure 110/70 mm Hg, heart rate 81/min, respiratory rate 16/min, and temperature 37.5℃ (99.5℉). The physical examination reveals abdominal tenderness and guarding in the periumbilical area. An abdominal ultrasound does not reveal an appendiceal abnormality.

The diverticulum is resected and sent for histologic evaluation. The result is shown in the exhibit. Which of the following statements is true?
