This traditionally consists of a magnifier (typically x10), a non-polarised light source, a transparent plate and a liquid medium between the instrument and the skin, and allows inspection of skin lesions unobstructed by skin surface reflections. Modern dermatoscopes dispense with the use of liquid medium and instead use polarised light to cancel out skin surface reflections. of porokeratosisThis glossary term has not yet been described.

PorokeratosisThis glossary term has not yet been described.

In porokeratosis, the cornoid lamella, known as the histopathologic hallmark of porokeratosis, is revealed by dermoscopic examination as a well-defined, white-yellowish peripheral annular structure (“white track”, ‘‘the outlines of a volcanic crater as observed from a high pointThis glossary term has not yet been described.’’).[1][2][3][4]

In disseminated superficialThis glossary term has not yet been described. actinic porokeratosis, the peripheral track may be hyperpigmentedThis glossary term has not yet been described..[5][6][7] Depending on the disease subtype and the stage of progression, the central part of porokeratotic lesions can demonstrate a brownish pigmentation, dotted or linear vesselsLinear mildly curved vessels considered irregular when different sizes shapes and curves with a haphazard or random distribution are presented and considered regular when short and fine (thin) linear vessels prevail various diagnoses, or a structureless whitish area. By dermoscopy, the diagnosisis the identification of the nature and cause of a certain phenomenon. Diagnosis is used in many different disciplines with variations in the use of logic, analytics, and experience to determine "cause and effect". In systems engineering and computer science, it is typically used to determine the causes of symptoms, mitigations, and solutions of porokeratosis is performed without difficulty, even in clinically atypical cases.
