Abstract

Juvenile ossifying fibromas (JOFs) are a rare group of fibro-osseous lesions, typically of odontogenic origin. Juvenile psammomatoid ossifying fibroma (JPOF) is one variant, that is, histopathologically distinguished by spherical ossicles resembling psammoma bodies. JPOF tumours are most commonly found in craniofacial skeletal structures and can be locally aggressive. Thus, early management by complete surgical excision is crucial for good outcomes, although recurrence is still possible. Secondary aneurysmal bone cyst (ABC) formation has been reported with JOF lesions, but less commonly with the JPOF variant. We describe an unusual case of JPOF that presented in the calcaneus with secondary ABC formation.
