Summary
Pediatric lumps are rarely cancerous (1%). Five key risk factors help identify malignant lesions in children, allowing for accurate reassurance in most cases.
Area of Science:
- Pediatric Surgery
- Oncology
- Dermatology
Background:
- Parental anxiety regarding childhood lumps is increasing.
- Prompt excision of all unexplained masses is often unnecessary and can cause undue stress.
Purpose of the Study:
- To review superficial lumps excised in infants and children.
- To identify risk factors for malignancy in pediatric superficial lumps.
- To guide clinical decision-making regarding lump excision.
Main Methods:
- Retrospective review of superficial lumps excised in pediatric patients.
- Analysis of clinical findings and risk factors associated with malignant lesions.
- Evaluation of diagnostic accuracy based on identified risk factors.
Main Results:
- Approximately 1% of excised superficial lumps in children are malignant.
- Five risk factors (neonatal onset, rapid growth, ulceration, deep fixation, firm mass >3cm) identify 80% of malignant lesions.
- In the absence of these risk factors, 99.7% accuracy in reassuring parents about benign nature.
- 6% of lumps spontaneously regress; >90% persist or enlarge and warrant elective excision.
Conclusions:
- A clinical assessment incorporating five risk factors can accurately reassure parents about the benign nature of most childhood lumps.
- Elective excision is recommended for persistent or enlarging lumps for cosmetic reasons, to prevent complications, and to diagnose rare malignancies.
- This approach balances the need for timely diagnosis with the avoidance of unnecessary anxiety and procedures.
