The breast and thigh lesion were both biopsied.
THIGH: A malignant tumor composed of lipoblast in a myxoid stroma.
Conclusion: mxyoid liposarcoma
BREAST: round to short spindle cells in a myxoid background. Vimentin positive. S100, CD68, CD34 and desmin negative.
Conclusion: myxoid liposarcoma
Quite a remarkable case of diffuse metastatic disease from a thigh liposarcoma including the rare occurance of breast metastases.
The thigh mass was present for several years prior and presumably metamorphasized into a malignancy.
