Dear Editor, Pityriasis lichenoides (PL) is an inflammatory skin disease of unknown etiology. The clinical spectrum of pityriasis lichenoides encompasses febrile ulcer-necrotic Mucha-Habermann disease (FUMHD), pityriasis lichenoides et varioliformis acuta (PLEVA), and pityriasis lichenoides chronica (PLC). Phototherapy is an effective and well-tolerated modality that is often successful for persistent PL or resistant to topical treatments. A retrospective observational study was conducted involving patients from the dermatology section of the University of Verona with a confirmed histological diagnosis of PLEVA and PLC accessed between January 2003 and June 2024.

In the normal young adults were studied electrical characteristics of the skin in five different regions. The results obtained have demonstrated presence of the topographic differences of the external resistance as well as capacity. It does not seem like that these differences can be correlated with the thickness at the corneal layer, but rather with the different glandular composition from one region to another and probably with the different hydration state of the skin. There were also demonstrated differences between sexes, characterized by the lower external resistance in males than in females.
