Treatment strategy for chondromyxoid fibroma of the sacrum.

We present a 59-year-old woman with a rare sacral chondromyxoid fibroma discovered incidentally and treated with curettage, bone grafting, and lumbopelvic fixation. At 1 year following surgery she remains symptom-free, has successfully fused her lumbopelvic construct and has no signs of tumor progression. The known literature contains only six previous reports of sacral chondromyxoid fibroma and discussion is presented on the diagnosis and treatment of this rare lesion.
