Abstract:
Eosinophilic pancreatitis is a rare form of chronic pancreatitis that is often mistaken for malignancy due to nonspecific presenting symptoms and noncontributory auxiliary exams. This clinical case report highlights a unique presentation of chronic pancreatitis. A middle-aged man developed abdominal pain, and repeat imaging showed an interval increase in size of a known pancreatic lesion. A core biopsy showed benign pancreatic tissue with eosinophilic-rich inflammation; IgE levels were also elevated. The patient was started on a prednisone taper, and repeat computed tomography 3 months later showed a decreased size of the pancreatic lesion. Correct and timely diagnosis of eosinophilic pancreatitis may avoid invasive unnecessary surgical procedures and allow for earlier initiation of appropriate therapy.
Insights
Eosinophilic pancreatitis, a rare chronic condition, can mimic cancer. Prompt diagnosis and steroid treatment effectively reduced a pancreatic lesion size in a unique case.
Area of Science:
- Gastroenterology
- Immunology
- Oncology
Background:
- Eosinophilic pancreatitis is a rare chronic pancreatitis subtype.
- It is frequently misdiagnosed as pancreatic cancer due to vague symptoms.
- Diagnostic challenges arise from nonspecific clinical presentations and inconclusive auxiliary examinations.
Observation:
- A middle-aged male patient presented with abdominal pain and a growing pancreatic lesion on imaging.
- Core biopsy revealed benign pancreatic tissue with eosinophilic inflammation and elevated IgE levels.
- The patient experienced symptom resolution and lesion reduction after prednisone treatment.
Findings:
- Eosinophilic pancreatitis can present atypically, mimicking malignancy.
- Elevated IgE levels and eosinophilic infiltration are key diagnostic indicators.
- Corticosteroid therapy demonstrates efficacy in managing eosinophilic pancreatitis.
Implications:
- Timely diagnosis of eosinophilic pancreatitis can prevent unnecessary surgical interventions.
- Early initiation of appropriate therapy, such as corticosteroids, is crucial.
- This case underscores the importance of considering rare pancreatitis subtypes in differential diagnoses.

01:24Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

01:27Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
