Chondromyxoid fibromas: a study of 10 cases.

Chondromyxoid fibroma (CMF) can be confused with a malignant tumor because of its potential for recurrence and occasional nuclear atypia. This study of 10 cases of CMF comprises 6 men and 4 women, with a mean age of 24.3 years. Tibia was the preferred site of involvement. The histology showed lobulated chondromyxoid matrix with peripheral fibrosis. Two cases had local recurrences following intralesional excision. The study emphasizes that despite nuclear atypia and recurrences, CMF is a benign disease.
