(a) Multivacuolated lipoblast surrounded by lipocytes that vary markedly in size and shape (H&E, 400x). (b) Area where univacuolar lipoblasts with scalloped nuclei predominate amid spindle cells with ovoid nuclei and the presence of ropey collagen (H&E, 400x). (c) Multinucleated giant cells with hints of ropey collagen (H&E, 400x). (d) Strikingly “bizarre” pleomorphic cell (H&E, 400x).
