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.

Scanning electron microscopy of a cross section. A. raisedhyperkeratotic area with cornoid lamella (x120). B. detail of thecornoid lamella showing compact keratin (x270). C. normal area withthe "basketball hoop" aspect and normal elimination of corneocytes (arrows) (x150)

f05: Scanning electron microscopy of a cross section. A. raisedhyperkeratotic area with cornoid lamella (x120). B. detail of thecornoid lamella showing compact keratin (x270). C. normal area withthe "basketball hoop" aspect and normal elimination of corneocytes (arrows) (x150)

Mentions: The cross-section with a magnification of 120 times easily identified the presence ofcornoid lamella. With a magnification of 270 and 150 times the tightly compacted keratinof the cornoid lamella could be demonstrated, losing the normal "basketball hoop"aspect, viewed on the surrounding keratin, where the normal liberation of corneocytescould also be seen (Figure 5).
