Three-dimensional aspects of superficial disseminated porokeratosis with scanning electron microscopy.

Almeida HL, Abreu LB, Rampon G, Silva RM, Rocha NM - An Bras Dermatol (2014 Nov-Dec)

Bottom Line: 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.

ABSTRACT
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.

Mentions: Histopathological examination of the punch biopsy material showed the presence of acornoid lamella and parakeratotic keratinocytes, consistent with the diagnosis ofporokeratosis (Figure 2). Scanning electronmicroscopy was performed on the punch surface, viewed at a 90º angle and on acrosssectional imaging of the lesion.
