MKI67 and lipoma: The Ki-67 labeling index (Table 2, Fig. 3i, j) was significantly lower in the lipoma-like components of MLSLC (range, 0.8–3.6; mean, 2.7; median, 2.9) than either in the myxoid components of MLSLC (range, 7.4–20.2; mean, 12.2; median, 11.2) (p < 0.001) or in the ordinary MLS (range, 6.4–22.2; mean, 14.4; median, 15.6) (p < 0.001).
