Abstract
Dermoscopy is a non-invasive technique that has been recently utilized for the diagnosis and management of many skin disorders. It also provides information about inflammatory skin diseases e.g. psoriasis, lupus, and so on. Psoriasis is a papulosquamous disease with variable distribution, morphology, severity and course, affecting about 1.5% of the population. In this study 218 cases of classic psoriasis were examined clinically and by dermoscopy. Dermoscopic signs found in psoriasis were bushy capillaries (dotted vessels), erythema and scales. Bushy capillaries presented in 99.5% of all cases, erythema presented also in 99.5% and scales presented in 92.7%. We found that, type and site of psoriasis have little or no effect on erythema but have significant effect on scales especially flexural psoriasis due to humidity, and skin phototype has no or little effect on dermoscopic finding in psoriasis as there is no significant effect of skin color on visibility of the bushy capillaries, erythema or scales. In conclusion, the well-known dermoscopic criteria of psoriasis, namely bushy capillaries, erythema and scaling are seen in dark skin as well as in those in light skin, in lesions of different locations, with the frequency of white scales varying among different body sites.
