However, in August 2021, the patient experienced a recurrence of symptoms, including intermittent right lower abdominal pain, with no fever or changes in bowel habits. A repeat colonoscopy showed a recurrence of ulcers at the appendiceal orifice (Figure 4 ). The patient was once again treated with mesalazine, leading to symptom relief. In December 2021, a follow-up colonoscopy demonstrated a marked improvement in the appearance of the ulcers at the appendiceal orifice (Figure 5 ). The patient reported the disappearance of abdominal pain and continued taking mesalazine regularly for a year.
