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

Primary orbital chondromyxoid fibroma is a rarely reported entity. A 34-year-old lady presented with painless, non-axial proptosis of the left eye of 6 months duration. Orbital imaging showed a supero-temporal mass with calcific foci and bone erosion. The mass caused globe compression resulting in choroidal folds. Anterior orbitotomy with complete mass excision was performed. The histopathology revealed a chondromyxoid fibroma. At 12-months follow-up, the patient is doing fine with no clinical recurrence. Chondromyxoid fibroma is an important differential diagnosis for bony orbital tumors.
