Summary
A solitary enchondroma in the fibula head showed chromosomal abnormalities, including t(8;17) and chromosome loss. This finding suggests benign and malignant cartilaginous tumors may share similar genetic changes.
Area of Science:
- Orthopedic Oncology
- Skeletal Dysplasias
- Cancer Genetics
Background:
- Enchondromas are common benign bone tumors, typically asymptomatic.
- Genetic analysis of enchondromas is crucial for understanding their pathogenesis.
- Previous studies have identified chromosomal aberrations in a limited number of enchondromas.
Observation:
- A solitary enchondroma was identified in the head of the left fibula of a 50-year-old patient.
- Histopathologic examination confirmed the diagnosis of enchondroma.
- Cytogenetic analysis revealed specific clonal chromosomal changes.
Findings:
- The enchondroma exhibited simple karyotypic abnormalities.
- Specific chromosomal aberrations included t(8;17)(q23;p13).
- Loss of chromosomes 9, 19, and 22 were also noted as clonal changes.
Implications:
- This case adds to the limited literature on chromosomal aberrations in enchondromas.
- The observed abnormalities may provide insights into the genetic landscape of benign cartilaginous tumors.
- Findings suggest potential shared chromosomal abnormalities between benign and malignant cartilaginous neoplasms.
