Validation of a physician global assessment tool for vitiligo extent: Results of an international vitiligo expert meeting.

Currently, vitiligo lacks a validated Physician Global Assessment (PGA) for disease extent. This PGA can be used to stratify and interpret the numeric scores obtained by the Vitiligo Extent Score (VES). We investigated the interrater reliability of a 5-point PGA scale during an international vitiligo workshop.

Pathologic Evaluation of Skin Tumors With Ex Vivo Dermoscopy With Derm Dotting.

Importance: Ex vivo dermoscopy (EVD) with derm dotting (DD) improves clinicopathologic correlation and the quality of diagnosis in skin tumors.

Objective: To compare the diagnostic performance of the standard method of skin biopsy processing with the practice of EVD with DD.

Design, Setting, And Participants: This retrospective study compares the diagnostic performance in 6526 skin biopsy specimens examined from 2008 to 2010 with a standard method of processing with 8584 biopsy specimens examined in 2015 with EVD and DD.
