Summary
Lymphoplasmacytic sclerosing pancreatitis, a rare condition, mimics cancer and presents a diagnostic challenge. This case highlights its distinct histological features, aiding in accurate diagnosis and management.
Area of Science:
- Gastroenterology
- Pathology
Background:
- Lymphoplasmacytic sclerosing pancreatitis (LPSP) is a rare pancreatic condition.
- It often presents diagnostic challenges due to its potential to mimic neoplastic processes.
Observation:
- A 61-year-old woman presented with left flank pain and normal pancreatic enzymes.
- Imaging revealed pancreatic tail thickening and ductal compression, with differentials including chronic pancreatitis and malignancy.
- Surgical exploration and resection were performed.
Findings:
- Gross examination showed a firm, yellowish-white mass in the pancreatic tail.
- Histological analysis revealed extensive fibrosis with a mixed inflammatory infiltrate, including lymphocytes, plasma cells, and eosinophils surrounding ducts.
- No evidence of malignancy was found.
Implications:
- Accurate diagnosis of LPSP is crucial to avoid unnecessary aggressive treatment for presumed cancer.
- Understanding the distinct histological features of LPSP aids in differentiating it from pancreatic neoplasms.
- This case contributes to the literature on LPSP, emphasizing its rare but significant clinical presentation.
