Pediatric epithelioid haemangioma with intra- and exra-articular involvement around the hip joint: A case report

Abstract

Background

Intra-articular tumors of the hip are rare in pediatric patients, often leading to delayed diagnosis and mismanagement. Improved imaging techniques have enhanced detection. However, differentiating benign from malignant tumors remains challenging. Additionally, managing these tumors in children require considering the impact on growth and long-term functions.

Case presentation

A 6-year-old boy presented with right lower extremity pain that worsened after a fall. Radiographs revealed cortical irregularities in the greater trochanter and the medial calcar of the femur. Magnetic resonance imaging showed irregular masses, and an incisional biopsy confirmed epithelioid haemangioma (EH). Post-biopsy, the patient's hip pain improved despite residual limping, avoiding further surgery.

Conclusion

This pediatric EH case emphasizes the importance of accurate diagnosis and tailored treatment in rare cases. Although partial resection improved symptoms, continued monitoring is vital due to the unpredictability of pediatric EH. Genetic analysis can potentially enhance diagnostic accuracy in future cases.
