obtained at the dermo–epidermal junction of ve dierent Asian volunteers’ forearm skin (Figures
14.20a-1 through 14.20a-5), the inactive melanocytes (arrows) can easily be identied according to their
oval shape and large nuclei, of which the mean diameter is about 7 μm. On the other hand, in the dermis
of the Asian volunteers’ skin, cells with strong THG contrasts and varied shapes are found within the
collagen bers (arrows in Figures 14.20b-1 through 14.20b-5). According to their locations and varied
shapes, these cells can be recognized as broblasts, melanophages, or lymphocytes depending on the
