Juvenile trabecular ossifying fibroma.

Juvenile ossifying fibroma (JOF) is an uncommon fibro-osseous lesion with highly aggressive clinical behavior, higher incidence in young adults, and a strong tendency to recur. Two categories, trabecular JOF (TrJOF) and psammomatoid JOF (PsJOF), based on histologic criteria and a distinct predilection for specific age groups have been identified. Juvenile trabecular ossifying fibroma of peripheral variety is an uncommon clinical entity with aggressive local behavior and high recurrence rate.
