>Figure 4: The second biopsy performed from the transient, apparently intact area showed no substantial difference, except for the thinner keratin layer measured by ocular micrometry as 50 μm and 25–30 μm in the first and second biopsies. 4a-b: Thinner keratin layer and similar distribution of vacuoles, compare with Fig.3a-b (H&E (20×)); 4c-d: Similar amount of intracytoplasmic lipid droplets (Scharlach and Oil Red-O) (40×), compare with fig.3c-d
