# Kawasaki Disease-Associated Pancreatitis in an Adolescent: A Case Report and Literature Review

## TL;DR

A 13-year-old boy with unexplained abdominal pain and elevated pancreatic enzymes was later diagnosed with Kawasaki disease, highlighting the need for awareness of this rare and atypical presentation.

## Contribution

This case report and literature review emphasize the atypical presentation of Kawasaki disease with pancreatitis in older children and adolescents.

## Key findings

- Pancreatitis can precede mucocutaneous symptoms in Kawasaki disease.
- Delayed diagnosis is common due to the absence of classic KD features.
- Older children and adolescents may present with unexplained abdominal pain and elevated pancreatic enzymes.

## Abstract

Background: Pancreatic involvement in Kawasaki disease (KD) is rare. Case presentation: A 13-year-old adolescent presented with severe epigastric pain, elevated pancreatic enzyme levels, and conjunctival injection, but he lacked a fever and the other classic features of KD. The patient was initially diagnosed with acute pancreatitis and treated conservatively. As his abdominal pain improved, mucocutaneous findings emerged, leading to a diagnosis of complete KD. A literature review was conducted to summarize reported cases of KD-associated pancreatitis. This review highlights the older age of affected patients, the variability in the timing of pancreatitis onset, and a tendency toward delayed diagnosis. Conclusions: Pancreatic involvement, including pancreatitis, can occur before typical mucocutaneous features and should be considered in older children and adolescents presenting with unexplained abdominal pain and pancreatic enzyme elevation. Increased awareness of this atypical presentation may help reduce diagnostic delay and support timely management.
