Figure 2. Histological findings of a skin biopsy specimen from
the left forearm
Pathophysiological examination with hematoxylin eosin staining. (a)
Appearance of eruptions. An eruption surrounded by four dotted markings
was investigated using microscopy. (b) Low magnitude (×40). Massive foam
cells (indicated by arrows) infiltrating into the superficial layer of
dermis. (c) High magnitude (×400). Eosinophilic substrate (asterisks),
probably indicating extracellular lipids, were observed between collagen
fibers. Additionally, foam cells are indicated by arrows.
