Chondroblastoma of the Navicular Bone: A Report of 2 Pediatric Cases

Two patients presenting to the clinic with midfoot pain were found to have pathologic fractures through chondroblastomas of the navicular bone. Patient 1 was a 15-year-old boy who experienced multiple recurrences despite more aggressive interventions. Patient 2 was a 13-year-old boy who experienced full recovery after lesion resection.

Navicular chondroblastoma is a rare site of presentation, with only 3 documented cases. Given the potential aggressive nature of these lesions with significant cortical destruction and soft-tissue extension, the navicular represents a difficult anatomic location to manage.
