title: Rare pediatric presentation of aneurysmal bone cyst with trabecular juvenile ossifying fibroma and ossifying fibroma.
abstract: Aneurysmal bone cyst (ABC) is a benign intraosseous lesion characterized by blood filled spaces of varying sizes associated with a fibroblastic stroma containing multinucleated giant cells, osteoid and woven bone. ABC can present either singly or in association with osseous neoplasms such as ossifying fibroma (OF), giant cell granuloma etc. Juvenile ossifying fibroma has two variants: psammomatoid JOF (PJOF) and trabecular JOF (TJOF). ABC formation in TJOF is very rare in pediatric patients with only three cases reported in literature till date to the best of our knowledge. We hereby report three pediatric cases of ABC, two of which were associated with TJOF and one associated with OF.
