Summary
This study presents two rare extracranial chondromas of the skull base. Findings suggest origins from cartilaginous remnants or the eustachian tube, highlighting their potential for development.
Area of Science:
- Neurosurgery
- Pathology
- Oncology
Background:
- Chondromas are benign cartilaginous tumors.
- Skull base chondromas are rare, particularly those of extracranial origin.
Observation:
- Presents two cases of extracranial chondroma at the skull base: one at the petrous pyramid apex, another in the infratemporal fossa.
- Surgical findings in one case indicated origin from the cartilaginous part of the eustachian tube.
Findings:
- Literature review reveals only three previously reported extracranial skull base chondromas and ten nasopharyngeal chondromas.
- The study discusses potential origins, including cartilaginous remnants at the basisphenoid and basiocciput, and the eustachian tube.
Implications:
- Understanding the origin of these rare tumors is crucial for accurate diagnosis and treatment planning.
- Further research into the embryological development of skull base cartilage may elucidate the pathogenesis of these tumors.
