# Autoimmune Pancreatitis Type 2, Biliary Cysts and Giardia lamblia

## TL;DR

This paper discusses a rare case of autoimmune pancreatitis in a teenager with a biliary cyst and a protozoal infection, exploring possible connections and long-term effects.

## Contribution

The paper presents a unique case linking autoimmune pancreatitis type 2 with biliary anomalies and Giardia lamblia infection.

## Key findings

- A 17-year-old boy was diagnosed with autoimmune pancreatitis type 2 alongside a biliary tract anomaly.
- The patient also had a concurrent Giardia lamblia infection, suggesting a possible pathogenic link.
- The case raises questions about the combined impact on long-term prognosis.

## Abstract

Autoimmune pancreatitis type 2 is a relatively novel entity with some still controversial issues. The current diagnostic algorithm relies on imaging studies and histology. Therapy includes corticosteroids with consequently low risk of relapse in the following year. However, the pathogenesis remains unclear, and data are insufficient for long-term prognosis. We have treated a 17-year-old boy whose autoimmune pancreatitis type 2 was revealed during surgery for a pre-existing biliary tract anomaly with concurrent protozoal infection. We discuss the co-occurrence of these conditions in terms of eventual pathogenesis correlation and combined effect on long-term prognosis.
