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

Abstract

Introduction & Chondromyxoid fi bromas 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 fi bromas frequently arise from the metaphysis of the long bones [18] . Chondromyxoid fi broma of the skull is extremely rare ( ● ▶ Table 1 ). Residual embryonic cartilage tissue may be the origin of skull chondromyxoid fi bromas. Here we describe a case of chondromyxoid fi broma located in the cerebellopontine angle.
