The encapsulated mass was composed of bland epithelial cells that formed a few branching ducts and small acinar clusters surrounded by a chondromyxoid
stroma (figure 4).

Coexisting lesions such as fibrous dysplasia, nonossifying fibroma, and chondromyxoid
fibroma have been described.
Morphologically, the differential diagnoses of this tumour includes chondromyxoid
fibroma and myxoid liposarcoma.
The differential diagnosis includes an eurysmal bone cysts, chondroblastoma, chondromyxoid
fibroma, giant cell reparative granuloma, nonossifying fibroma, Langerhans' cell histiocytosis, synovial sarcoma, and high-grade central osteosarcoma.
Differential diagnosis of the findings included benign fibrous lesions of bone-like non-ossifying fibroma and odontogenic fibroma, myxoma and chondromyxoid
fibroma or even fibrosarcoma.
In the differential diagnosis chondromyxoid
fibroma and osteitis fibrosa cystica were considered (Figs 1 a & b).
Lorenz diagnosed a chondromyxoid
fibroma, a non-malignant bone tumor that usually occurs in the limbs and feet.
We report a very rare case of a chondromyxoid
fibroma of the mastoid portion of the temporal bone in a 38-year-old woman who presented with left-sided hearing loss.
15,18) Primary lesions most frequently associated with ABC (in order of frequency) include giant cell tumor of bone, chondroblastoma, chondromyxoid
fibroma, and fibrous dysplasia, particularly in pregnancy.
A bite sign has also been described with chondromyxoid
fibroma, a rare benign cartilaginous tumor of the bone.
