Photomicrographs of representative lipoblastoma histologies. A: Classic lipoblastoma has stellate and spindle mesenchymal cells, monovacuolated and multivacuolated lipoblasts, adipocytes, and intercellular mucin. B: Myxoid lipoblastoma is characterized by abundant intercellular mucin. C: Lipoma-like lipoblastoma has mostly mature adipocytes with only a rare lipoblast. D: Hibernoma-like lipoblastoma has polyvacuolated adipocytes with granular cytoplasm with some cells having central nuclei.
