Summary
This case report details a rare co-occurrence of pancreatic arteriovenous malformation (P-AVM) and esophageal cancer in a 59-year-old man. Surgical intervention was successful, with the patient experiencing a good postoperative recovery.
Area of Science:
- Vascular Malformations
- Gastrointestinal Oncology
- Surgical Pathology
Background:
- Pancreatic arteriovenous malformations (P-AVMs) are rare vascular anomalies.
- Co-occurrence of P-AVM and esophageal cancer is exceptionally uncommon.
- Chronic pancreatitis can be associated with vascular abnormalities.
Observation:
- A 59-year-old male presented with upper abdominal pain and was diagnosed with esophageal cancer.
- Imaging revealed a pancreatic tail lesion consistent with P-AVM and associated chronic pancreatitis.
- Endoscopic and angiographic studies confirmed the pancreatic vascular anomaly and esophageal malignancy.
Findings:
- Histological examination confirmed squamous cell carcinoma of the esophagus.
- The resected pancreas showed P-AVM secondary to severe chronic pancreatitis, with ductal rupture and stones.
- Abnormal vessels with thrombi were noted within the pancreatic malformation.
Implications:
- This case highlights the importance of considering rare vascular pathologies alongside common malignancies.
- Multidisciplinary management is crucial for complex cases involving coexisting conditions.
- Understanding the pathogenesis of P-AVM in chronic pancreatitis may inform future diagnostic and therapeutic strategies.
