Mobile teledermatology for skin tumour screening: Diagnostic accuracy of clinical and dermoscopic image tele-evaluation using cellular phones

Background  The ability to diagnose malignant skin tumours accurately and to distinguish them from benign lesions is vital in ensuring appropriate patient management. Little is known about the effects of mobile teledermatology services on diagnostic accuracy and their appropriateness for skin tumour surveillance.

Interobserver variability of teledermoscopy: an international study.

Background  Teledermoscopy is a rapidly developing field of dermatology with studies demonstrating excellent agreement with face‐to‐face diagnosis. However, we are unaware of studies evaluating interobserver variability in diagnosis between dermatologists from different continents. This evaluation is important to determine the robustness of teledermoscopy and allow comparisons to be made between different studies.

A randomized, phase IIa exploratory trial to assess the safety and preliminary efficacy of LEO 43204 in patients with actinic keratosis.

LEO 43204 is a novel ingenol derivative in development for the treatment of actinic keratosis.

Heritability of naevus patterns in an adult twin cohort from the Brisbane Twin Registry: A cross-sectional study

Heritability of naevi counts is widely acknowledged as a potential surveillance parameter for prevention purposes. The contribution of heritability to the changes seen in naevus number and morphology over time and their corresponding dermoscopic characteristics is unknown, but is important to understand in order to account for adequate prevention measures.

Distribution Analyses of Acquired Melanocytic Naevi on the Trunk

Acquired melanocytic naevi (AMN) are a well-known risk factor for the development of melanoma. Whereas previous studies have reviewed AMN distributions on individual body sites, the clinical distribution of AMN on the adult trunk has not been thoroughly investigated. We studied 40 participants with 1,282 naevi >5 mm, of which 781 were located on the trunk. Remarkably, 70% of these truncal naevi were located on the back and we produced a continuous mathematical description of decreasing naevus frequency moving dorsolaterally from the back midline. Furthermore we found that for both sexes the mean naevus size was larger on the front as well as on the lower trunk. This distinct pattern, whilst probably being unwritten knowledge (in the dermatology domain), has not been discussed before.
