Summary
Non-ossifying fibromas, rare bone tumors, were observed in two 4-year-old boys. Corticosteroid treatments proved ineffective for these osseous cavities.
Area of Science:
- Pediatric Orthopedics
- Skeletal Radiology
Background:
- Non-ossifying fibromas (NOFs) are common benign bone tumors, typically occurring in children and adolescents.
- While generally asymptomatic and self-resolving, unusual presentations warrant further investigation.
Observation:
- This report details two rare cases of non-ossifying fibromas in 4-year-old boys.
- Both cases exhibited partial cystic degeneration, an uncommon feature.
- The osseous lesions did not respond to corticosteroid therapy.
Findings:
- The presented cases highlight an unusual demographic (4-year-old boys) and pathological feature (cystic degeneration) of non-ossifying fibromas.
- Corticosteroids were ineffective in treating these specific non-ossifying fibromas, suggesting limitations in this therapeutic approach for certain presentations.
Implications:
- These findings suggest that non-ossifying fibromas with cystic degeneration may require alternative management strategies beyond corticosteroid injections.
- Further research into the specific mechanisms of cystic degeneration in NOFs and their response to various treatments is warranted.
- This case series contributes to the understanding of rare pediatric bone tumor variations and informs clinical decision-making.

03:14Notch Signaling Pathway
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

01:23Cystic Fibrosis: Pathogenesis
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...
