[Chondroid lipoma].
Chondroid lipoma had not been defined until 1993. Here presented case was a 30-year old woman with a well limited soft tissue tumour of the left thigh. In histology, the encapsulated tumour consisted of mature adipocytes in common lipoma like areas and of a chondroid component in which lipoblastic or hibernoma like cells were surrounded by a myxohyaline matrix. Both components were connected and mutually transient. Tumour cells showed S-100 protein and laminin positivity in immunohistochemistry. Cells of the chondroid component had distinct ultrastructural features of adipose and cartilagineous differentiation. Chondroid lipoma is a benign tumour which is to be distinguished from extraskeletal myxoid chondrosarcoma and myxoid liposarcoma.
