Insights
A liver tumor in an infant, mesenchymal hamartoma, showed natural regression and calcification over one year without treatment. The child remains healthy three years later, indicating potential for spontaneous resolution.
Area of Science:
- Pediatric oncology
- Hepatology
- Medical imaging
Background:
- Mesenchymal hamartoma of the liver is a rare benign liver tumor in infants.
- While typically treated surgically, its natural history is not fully understood.
Observation:
- A six-month-old male infant presented with a mesenchymal hamartoma of the liver.
- The tumor was managed conservatively without intervention.
Findings:
- Serial computed tomography (CT) scans demonstrated significant tumor regression and calcification within one year.
- The infant exhibited no adverse effects and maintained good health.
Implications:
- This case suggests that mesenchymal hamartoma of the liver may undergo spontaneous regression and calcification.
- Conservative management could be a viable option for select cases, warranting further investigation.
- This finding has implications for treatment strategies in pediatric liver tumors.
Abstract:
We report a six-month-old male infant with mesenchymal hamartoma of the liver which was left untreated. Repeat CT scan 1 year later showed regression and calcification of the tumor. The child is well 3 years later.
