Chondromyxoid fibromas (CMF) are benign cartilaginous bone tumors which are found most frequently in the metaphyses of long bones. They comprise less than 1% of primary bone neoplasms. We report an interesting incidental case of a 43-year-old woman with a CMF of the left pubic ramus, presenting with complaints of gradual onset of left groin pain over a period of 2 years. According to radiological examination, a malign chondroid bone tumor was excluded, and histopathological examination confirmed the diagnosis of CMF. The patient underwent aggressive curettage and bone grafting 6 years ago. Pelvic bones are encountered as rare localizations for CMFs. Pubic ramus is accepted as an exceptional site for this benign bone tumor of cartilaginous origin. To our knowledge, no any other CMF case in this localization has been reported in the literature. In atypical regions such as the pelvis and pubic ramus, CMF must be considered for differential diagnosis of malign tumors.
