Facilitations in the Clinical Diagnosis of Human Scabies through the Use of Ultraviolet Light (UV-Scab Scanning): A Case-Series Study.

Background: To confirm the suspicion of scabies, dermatologists have one pathognomonic sign, "the tunnel" through which digs into the epidermis. Light microscopy is considered the most reliable procedure, but it is time-consuming and operator-dependent. Recently, dermoscopy has greatly improved the chances of recognizing mite in situ, but it is still linked to the examiner's experience and to the magnification capability of the device used.

"Eczema" of the nape: A marker of pthiriasis capitis.

Pthirus pubis usually infests the pubis, inguinal folds, buttocks and perianal region. In hairy males or when the infestation is longstanding, this louse can also occur on the thighs, abdomen, chest, axillae and beard. Eyelashes may be involved in children.

The Mite-Gallery Unit: A New Concept for Describing Scabies through Entodermoscopy.

Scabies has always represented a diagnostic challenge for dermatologists, especially in subclinical cases or in atypical ones due to the coexistence of other diseases. Fortunately, dermatoscopy has enabled easier and faster in situ diagnosis. The aim of this study is to examine old and new dermatoscopic signs that produces on the skin during its whole life cycle through (dermatoscopy with an entomological focus) which, unlike traditional optical microscope examination, allows the local micro-environment to be preserved intact.

Topical calcipotriol as a new therapeutic option for the treatment of clear cell acanthoma.

Although uncommonly diagnosed, clear cell acanthoma represents an original source of speculative interest for dermatologists. Due to its clinical variability, it is often only recognized accidentally after histology. Dermoscopy has improved the reliability of clinical diagnosis of typical clear cell acanthoma thanks to the vascular pinpoint pattern and desquamative, peripheral collarette.
