From: Incomplete paresis of the sciatic nerve due to massive atypical lipoma of the pelvis: a case report
A) Massive tumor with fatty appearance after surgery. B) and C) Adipocytes and some atypical nuclei (see arrows, B: H&E 200× and C: H&E 400×) as a typical finding of a well-differentiated liposarcoma (atypical lipoma). D) Assessment of cell proliferation by detection of Ki67 antigen shows the low proliferation index of the atypical lipoma (see arrows, Ki67 staining 400×).
