One of the most common subtypes of gnathic osteosarcoma is chondroblastic osteosarcoma, which is made up of malignant, osteoid-producing cells with admixed islands and lobules of malignant cartilaginous or chondrosarcomatous tissue (figure 2).
Sarcomatoid MMs usually consist of spindle cells but can be composed of lymphohistiocytoid cells and/or may also contain heterologous rhabdomyosarcomatous, osteosarcomatous, or chondrosarcomatous elements.
Secondary patterns of sarcomatoid MM may demonstrate anaplastic and giant cells with a differential diagnosis of high-grade sarcoma, osteosarcomatous areas with a differential diagnosis of osteosarcoma, or chondrosarcomatous areas with differential diagnosis of chondrosarcoma.

Foci of divergent differentiation are not uncommon, with rhabdomyosarcomatous, osteosarcomatous, chondrosarcomatous, and angiosarcomatous elements appearing in some cases.
Pathologically, the differential diagnoses of osteoma include ossifying fibroma, osteoblastoma, osteosarcoma, and chondrosarcomatous osteosarcoma.
Here, we present one such case in which the tumor showed CRCC with extensive sarcomatoid changes containing heterologous elements in the forms of chondrosarcomatous and osteosarcomatous differentiation.
The sarcomatous element represented about 70% of the tumor, with 5% composed of osteosarcomatous and chondrosarcomatous components.
Although initial sections did not show a sarcomatous component, additional sections did reveal chondrosarcomatous foci that were characterized by a chondroid matrix surrounding numerous atypical nuclei (figure 3).
Rhabdoid, rhabdomyosarcomatous, and chondrosarcomatous components may be evident as well.
Secondary patterns of sarcomatoid MM may demonstrate anaplastic and giant cells with a differential diagnosis of malignant fibrous histiocytoma, osteosarcomatous areas with a differential diagnosis of osteosarcoma, or chondrosarcomatous areas with a differential diagnosis of chondrosarcoma.
