Key result
A case of primary uterine osteosarcoma in a 56-year-old woman presented diagnostic challenges due to its anaplastic nature, with osteoid features confirmed by electron microscopy.
Case Report (n=1)
Reports a rare case of primary uterine osteosarcoma, highlighting diagnostic challenges and electron microscopy findings.
Rare uterine osteosarcoma may mimic anaplastic malignancies; extends sparse literature but leaves diagnostic standards open.
Uterine osteosarcoma represents an extremely rare pure heterologous sarcoma of the uterus. In the present case osteosarcoma occurred primarily in the uterine cavity of a 56-year-old woman. The tumor was anaplastic and the presence of different proliferative patterns caused differential diagnostic problems with various malignant tumor types. The osteoid features of extracellular matrix were demonstrated by electron microscopy. Clinical and pathological features of previously reported cases of uterine osteosarcoma are critically reviewed.
