METHODS
Two cases of chondroma at the skull base, most probably of extracranial origin, are presented: one at the apex of the petrous pyramid and the other in the infratemporal fossa.
RESULTS
In the second case, the surgical findings suggested that the tumor originated in the cartilagineous part of the eustachian tube. The world literature was reviewed and only three cases of extracranial chondromas at the skull base, and ten cases of chondromas of the nasopharynx have been described so far.
CONCLUSIONS
The potential origins of chondromas at the skull base are discussed: Cartilagineous remnants at the basisphenoid and basiocciput or the cartilagineous part of the eustachian tube seem to be the most probable origin.
方法
本文报告两例颅底软骨瘤，极有可能起源于颅外：一例位于岩尖，另一例位于颞下窝。
结果
在第二例中，手术所见提示肿瘤起源于咽鼓管的软骨部分。查阅世界文献，迄今为止仅描述了三例颅底颅外软骨瘤和十例鼻咽部软骨瘤。
结论
讨论了颅底软骨瘤的可能起源：蝶骨基底部和枕骨基底部的软骨残余或咽鼓管的软骨部分似乎是最可能的起源。
