Primary chondromyxoid fibroma of the orbit: An orbital mass with calcification

Chondromyxoid fibroma of the iliac bone: a brief radiological review

Chondromyxoid fibroma (CMF) is a rare, benign bone tumour most commonly located within the metaphyseal region of the long bones surrounding the knee joint. Here, we present an interesting case of a young woman in her early 20s with CMF of the left iliac bone and include a literature review of comparable studies with an emphasis on radiological findings and important differential diagnoses to be aware of in this atypical location.

Primary Orbital Chondromyxoid Fibroma: A Cause of Monosymptomatic Periocular Pain

Chondromyxoid fibroma (CMF) is a very rare entity, accounting for <1% of all bone tumours. So far, only 4 cases have been reported with the orbit as primary location. Here, we present a case of orbital CMF with periocular pain as the presenting symptom and as the only symptom when the tumour recurred after surgery. A 41-year-old man underwent a CT scan and later an MRI as part of evaluation for left periocular pain that had persisted for a year. Clinical examination was normal. CT and MRI revealed an irregular mass in the lateral part of the left orbital roof. The tumour was removed by curettage, and histopathological examination showed a CMF. The pain was absent for 3 months. A second MRI 5 months postoperatively revealed a recurrence, which was removed surgically, resulting in pain alleviation. In conclusion, CMF is a potential cause of periocular pain, and persistent periocular pain with normal clinical findings should warrant a CT or MRI scan.
