Bone Formation by Intramembranous Ossification01:29

Bone Formation by Intramembranous Ossification

16.1K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...

Compact Bone01:27

Compact Bone

22.3K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

The Retinoblastoma Gene

3.7K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Bone Disorders

8.0K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Sutures of the Skull01:22

Sutures of the Skull

13.8K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Summary

Juvenile trabecular ossifying fibroma (JTOF) is an aggressive jaw tumor in young patients. Complete surgical removal of this recurrent tumor offers the best chance for successful treatment.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Pathology
  • Oncology

Background:

  • Juvenile ossifying fibroma (JOF) is a rare, aggressive fibro-osseous lesion with high recurrence rates, predominantly affecting young individuals.
  • Two histological subtypes, trabecular JOF (TrJOF) and psammomatoid JOF (PsJOF), exhibit distinct age predilections.
  • Peripheral juvenile trabecular ossifying fibroma (JTOF) is a particularly uncommon variant known for its aggressive local behavior and propensity for recurrence.

Observation:

  • This case report details an aggressive JTOF in the anterior mandible of a 13-year-old male with a history of recurrence.
  • The lesion presented with aggressive clinical behavior, characteristic of JTOF.

Findings:

  • Complete surgical resection, including the involved periodontal ligament and periosteum, was performed to achieve radical tumor removal.
  • Histopathological examination confirmed the diagnosis of juvenile trabecular ossifying fibroma.

Implications:

  • Aggressive JTOF requires thorough surgical excision to minimize recurrence risk.
  • Early diagnosis and complete resection are crucial for managing this rare and aggressive odontogenic tumor.
  • Long-term follow-up is essential to monitor for any signs of recurrence after treatment.
