The three-dimensional findings of the surface and from a cross section from a case of
disseminated superficial porokeratois using scanning electron microscopy are
reported. On the surface of the skin, irregular keratin with a serpiginous
distribution was seen. A gross aspect of keratin in the hyperkeratotic wall was also
observed and compared to the normal area, in which the release of corneocytes seemed
normal. The cross-sectional imaging easily identified the cornoid lamella, with
compact keratin surrounded by normal stratum corneum.
