“…However, although their presence is considered ‘prerequisite' for the diagnosis of PP, dotted vessels do not represent a specific dermoscopic feature, since they can be seen in several other inflammatory skin diseases, including dermatitis and pityriasis rosea [8,10,11]. Accordingly, the dermoscopic differentiation between the latter entities and PP is not based on vessel morphology, but on the evaluation of additional criteria, namely the arrangement of vessels and the color and distribution of scales [8].…”

Background: Scarce evidence exists on the dermoscopic pattern of psoriasis on specific body sites. Objective: To describe the dermoscopic characteristics of psoriatic plaques located on the scalp, face, folds, palms, soles and genitalia. Methods: Dermoscopic images of psoriatic lesions located on the aforementioned body sites were retrospectively evaluated for the presence of predefined criteria. Results: A total of 139 lesions from 85 patients were included in the study. Dotted vessels were the commonest dermoscopic criterion (97.1%) followed by white scales (64.7%), while vessel distribution was regular in 87.7% of cases. Regularly distributed dotted vessels represented a constant finding in all locations, while the frequency of white scales varied significantly among different body sites. Conclusion: The well-known dermoscopic criteria of psoriasis can also be seen in lesions located on the scalp, face, palms, soles, folds and genitalia, with the frequency of white scales varying among different body sites.

“…Several inflammatory skin diseases have been shown to exhibit characteristic and repetitive dermoscopic patterns. [3][4][5] A recent study 3 investigated the diagnostic accuracy of certain dermoscopic criteria of psoriasis, providing evidence that the method may significantly enhance the clinical differentiation from dermatitis, pityriasis rosea and lichen planus. The dermoscopic pattern of psoriatic plaques of the patient presented herein is in agreement to the findings of the latter study.…”

Pityriasis rubra pilaris (PRP) is a relatively uncommon skin disease, clinically characterized by follicular keratotic plugs, red to orange plaques and palmoplantar hyperkeratosis. PHOTOLETTER TO THE EDITOR AbstractPityriasis rubra pilaris (PRP) is a relatively uncommon entity that often has to be clinically differentiated from other erythematosquamous skin diseases, such as psoriasis. Dermoscopy has already been shown to enhance clinical evaluation of inflammatory skin conditions and dermoscopic patterns of various diseases, including psoriasis, have been documented. In the current manuscript we present the dermoscopic findings observed in two patients suffering from PRP and psoriasis, respectively. The dermoscopic pattern of PRP consisted of round/oval yellowish areas surrounded by vessels of mixed morphology. The latter findings are clearly distinct from the dermoscopic features of psoriasis, which have been extensively investigated previously and are presented also in the psoriatic patient herein. This observation represents an initial indication that dermoscopy could be of value in differentiating between the two entities. (J Dermatol Case Rep. 2013; 7(1): 20-22)

“…Our case also indicate that PCFCCL exhibits a characteristic dermoscopic pattern consisting of fine short linear vessels and, vascular structures resembling spermatozoa which was described in early stage of mycosis fungoides and never in PCFCCL [5]. However, prospective studies with long term follow-up are needed to determine the value of these dermoscopic criteria .…”
