Chondromyxoid fibroma of the skull base: a case report of an unusual location.

摘要

Chondromyxoid fibromas are rare benign tumors of the bone and constitute only 0.5% of all primary bone tumors [13]. They originate from cartilaginous tissue and usually occur in young adults. Chondromyxoid fibromas frequently arise from the metaphysis of the long bones [18]. Chondromyxoid fibroma of the skull is extremely rare ( Table 1). Residual embryonic cartilage tissue may be the origin of skull chondromyxoid fibromas. Here we describe a case of chondromyxoid fibroma located in the cerebello-pontine angle.
