Cutaneous manifestations in COVID‐19: a new contribution
2020
Abstract We have read with great interest Dr Recalcati’s review about skin manifestations in COVID‐19 as it is the first report on this subject1. In a recent review on clinical characteristics of coronavirus disease 2019 in China, rash was observed in 0,2% of cases2. However, from the trained eyes of a dermatologist, this percentage may be higher.
Exogenous and endogenous provocation of psoriasis. A contribution to the Koebner phenomenon.
1974
Previous literature reports as well as own investigations concerning exogenously and endogenously induced Koebner-reactions in psoriatics are presented. The time interval between irritation and the Koebner-reaction is emphasized. It is proposed, that the intensity of the psoriatic reaction is mediated by circulating DHEA-deficiency. Hypothetical models are presented which allow to explain the different developmental rates of psoriatic lesions in relation to the type of irritation, the area affected and the subsequent proliferative responses.
Autofluorescence Imaging of the Skin Is an Objective Non-Invasive Technique for Diagnosing Pseudoxanthoma Elasticum
2021
Pseudoxanthoma elasticum (PXE) is a rare multisystemic autosomal recessive connective tissue disease. In most cases, skin manifestations of PXE are the first to develop, followed later by severe ocular and cardiovascular complications. In our present study, in addition to dermoscopy, we introduced novel techniques, autofluorescence (AF) and diffuse reflectance (DR) imaging for the assessment of affected skin sites of five PXE patients. PXE-affected skin areas in most skin sites showed a previously observed pattern upon dermoscopic examination. With the novel imaging, PXE-affected skin lesions displayed high AF intensity. During our measurements, significantly higher mean, minimum and maximu…
