We describe a case of chondromyxoid fibroma of the mastoid bone extending along the occipital bone in a 48-year-old man. The presence of this tumor was heralded solely by aural fullness caused by otitis media with effusion. The tumor arose from the mastoid cavity, eroding the entire petrous portion, and invading the foramen magnum and jugular foramen. The occurrence of this tumor is exceedingly rare, and, to our knowledge, this is only the second article in the literature that describes a chondromyxoid fibroma of the mastoid region. The clinical appearance of this tumor and its light- and electron-microscopic findings are presented with reference to other articles.
我们报道了一例48岁男性乳突骨软骨黏液样纤维瘤沿枕骨延伸的病例。该肿瘤的出现仅表现为分泌性中耳炎引起的耳部闷胀感。肿瘤起源于乳突腔，侵蚀整个岩部，并侵犯枕骨大孔和颈静脉孔。这种肿瘤的发生极为罕见，据我们所知，这是文献中第二篇描述乳突区软骨黏液样纤维瘤的文章。结合其他文献，本文介绍了该肿瘤的临床表现及其光镜和电镜检查结果。
