Heterogeneous differentiation in the form of rhabdomyosarcomatous, chondrosarcomatous
and osteosarcomatous may be present.
The sarcomatous spindle cell component may occasionally contain osteosarcomatous, chondrosarcomatous
, or rhabdomyosarcomatous elements.
Calcification may be observed within the primary tumour as well as metastases on CT scan, which would likely represent an osteosarcomatous or chondrosarcomatous
component to the tumour .
The coexistence of invasive ductal carcinoma and malignant phyllodes tumor with liposarcomatous and chondrosarcomatous
differentiation in the same breast in a post-osteosarcoma case.
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).

67) Furthermore, sarcomatoid MM with either osteosarcomatous or chondrosarcomatous
differentiation is known to be typically negative for keratin staining.
Here, we present cytology and histopathology of two cases of malignant phyllodes tumour; one presenting with squamous differentiation and chondrosarcomatous
area which was diagnosed as benign phyllodes tumour with metaplastic squamous cells and another with extremely rare granular change in the stromal component, which could not be diagnosed cytologically and reported as inconclusive for opinion.
Foci of divergent differentiation are not uncommon, with rhabdomyosarcomatous, osteosarcomatous, chondrosarcomatous
, and angiosarcomatous elements appearing in some cases.
For sarcomatoid mesothelioma, these histologic variants may comprise heterologous (osteosarcomatous, chondrosarcomatous
, and rhabdomyosarcomatous) elements and desmoplastic mesothelioma.
Dedifferentiated component exhibiting chondrosarcomatous
dedifferentiation is very rare with only few cases reported in literature.
Pathologically, the differential diagnoses of osteoma include ossifying fibroma, osteoblastoma, osteosarcoma, and chondrosarcomatous
