Summary
A rare ampullary hamartoma mimicked cancer in a 67-year-old man. This benign tumor was successfully treated with local excision, highlighting an alternative to radical surgery for specific ampullary lesions.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Ampullary tumors are rare and challenging to differentiate from periampullary tumors clinically, radiologically, and histologically.
- Most ampullary and periampullary tumors are malignant, necessitating radical surgical intervention.
- Sporadic ampullary hamartomas are benign neoplasms that can mimic malignant tumors.
Observation:
- A 67-year-old male patient presented with a sporadic ampullary hamartoma.
- The hamartoma presented symptoms and imaging findings that simulated malignancy.
- Distinguishing this benign hamartoma from malignant ampullary or periampullary tumors was difficult.
Findings:
- The patient's ampullary hamartoma was successfully treated by local excision.
- The surgical approach involved a transverse duodenotomy for complete tumor removal.
- Histological examination confirmed the benign nature of the hamartoma post-excision.
Implications:
- Local excision can be a viable and effective treatment for select sporadic ampullary hamartomas.
- This case suggests that not all ampullary tumors require radical surgery, offering a less invasive option.
- Accurate diagnosis and careful patient selection are crucial for successful conservative management of ampullary lesions.
