Summary
Aneurysmal bone cysts can be primary or secondary to other jaw lesions. This study reports two cases, one primary and one associated with a cementifying fibroma, highlighting their controversial origins.
Area of Science:
- Oral and Maxillofacial Surgery
- Pathology
- Oncology
Background:
- Aneurysmal bone cyst (ABC) is a rare, benign, expansile bone lesion.
- Its etiology remains controversial, with theories suggesting it arises primarily or secondary to other bone pathologies.
Observation:
- Two cases of ABC in the jaws are presented: a primary lesion in a 13-year-old and a secondary lesion in a 5-year-old associated with cementifying fibroma.
- Both cases involved significant hemorrhage and required blood transfusion.
- Histopathological confirmation was achieved through biopsy.
Findings:
- The primary ABC presented with marked hemorrhage, while the secondary ABC showed less pronounced bleeding.
- Both lesions were treated surgically (curettage for primary, excision for secondary) and showed no recurrence after two years.
- Serial sectioning of biopsy specimens is crucial for detecting associated lesions.
Implications:
- This study contributes to the understanding of ABC origins in the African population.
- It underscores the importance of thorough histopathological examination to differentiate primary from secondary ABCs.
- Early and accurate diagnosis and treatment are vital for favorable outcomes.

01:26Bone Markings
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

01:30Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:09Spongy Bone
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

01:55Bone Structure
Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.
01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
