Juvenile ossifying fibroma (JOF) is an uncommon, benign, bone-forming neoplasm seen in the craniofacial bones. It is distinguished from other fibro-osseous lesions primarily by its age at onset, clinical presentation, and potential aggressive behavior. Occasionally JOF may grow aggressively and extend to involve the orbits and skull base, resulting in serious cosmetic and functional problems. A radical surgery is not advisable in a pediatric age group. We describe a case of JOF of the maxilla removed by sublabial approach conservatively, but completely without compromising the aesthetic looks of the young patient.

Understanding the developmental sequence characteristics of the vertebral and appendicular skeletons of the larvae and juveniles of Larimichthys crocea (Naozhou population) can provide theoretical basis for seedling cultivation, environmental adaptation, and taxonomic identification. The cartilage-bone double staining method was used to stain, observe, and analyse the vertebrae, pectoral fins, anal fins, caudal fins, and dorsal fins of the larvae and juveniles of L. crocea (0-30 days post-hatching [DPH]).

Objective: To assess the sclerostin, β-catenin, and tryptase expression in fibro-osseous lesions (FOL) of the jaws.
Subjects And Methods: Immunohistochemistry analysis was performed for these proteins on FOL and non-lesional bone. The sclerostin-positive cells were scored from 0 (no expression) to 3 (high expression).

Zebrafish and medaka are valuable model vertebrates for genetic studies. The advent of CRISPR-Cas9 technology has greatly enhanced our capability to produce specific gene mutants in zebrafish and medaka. Analyzing the phenotypes of these mutants is essential for elucidating gene function, though such analyses often yield unexpected results.

Ossifying fibroma (OF) is a rare benign fibro-osseous neoplasm developing mostly in maxillo-facial bones. OF is divided in cemento-ossifying fibroma (COF), juvenile trabecular ossifying fibroma (JTOF) and psammomatoid ossifying fibroma (PSOF). The aim of this systematic review was to synthetize the existing literature on OF, investigating the clinical and radiological parameters related to the different forms of the disease, and to compare the treatment modalities according to their associated recurrence rate.

Trabecular juvenile ossifying fibroma (TrJOF) is a rare, benign, fibro-osseous lesion that predominantly affects children and adolescents. The lesion is locally aggressive, has a high recurrence rate, and is often misdiagnosed due to its clinical and radiographic similarities to other lesions. A seven-year-old female presented with a history of swelling and pain on the right side of her face for the last month.
