Background: Allied disorders of Hirschsprung’s disease (ADHD) exhibit symptoms akin to those of Hirschsprung’s disease, primarily characterized by intestinal obstruction, bowel dilatation, and chronic constipation. The occurrence of amyloid complications in patients with ADHD is infrequent. In this report, we present a case of ADHD with intestinal ulcers as the initial gastrointestinal manifestation, and subsequent pathological examination revealed the presence of amyloid deposits in the colonic mucosa.
Case Report: A male patient, aged 20, exhibited recurring abdominal distension and intestinal obstruction for a duration of three years. Multiple colonoscopies revealed the presence of recurrent colonic ulcers, with pathological examination indicating the existence of amyloid deposits within the mucosal layer of the colon. Abdominal CT scans suggested colonic dilatation. Following a multidisciplinary consultation, a subtotal resection of the colon was performed, and subsequent postoperative pathology confirmed a decrease and absence of myenteric plexus ganglion cells. Considering the patient’s symptoms and the findings from the postoperative pathology, a diagnosis of ADHD was made. The patient’s symptoms resolved postoperatively and he was discharged from the hospital and followed up for 1 year in stable condition.
Conclusion: Our study highlights the potential association between ADHD and the initial presentation of recurrent colonic ulcers, accompanied by amyloid deposition in the intestinal mucosa. This finding suggests a possible pathogenic mechanism for ADHD and offers a novel perspective on its diagnosis.
