The authors reported 2 cases and 10 cases of collected literature reported a total of 12 cases of bone myxoid fibroma. Age 27 to 74 years old. 4 males and 8 females. 6 cases (50%) of femur, 3 cases (25%) of pelvis, 2 cases of sacrum, and 1 case of ulna. The main clinical symptoms were local pain. The authors pointed out that myxoid fibroma is a benign tumor that usually occurs in the mandible, but is rare in bones other than the jaw. Histologically, however, it is a calcified or ossified tumour of varying amounts composed of fibrillar and mucoid-like matrices, and the cells may be composed of spindle cells or astrocytes.
