Unlike other rosacea therapies which need daily takings or applications over long periods, the edge of lasers and light-based therapies (LLBT) is the limited number of sessions to achieve improvement. The proper selection of the adequate physical device in accordance with the patients’ skin features and rosacea-related signs and symptoms should be considered and the management with physical sources should be updated as new data become available. This article reviews and discusses the current use of lasers and light-based therapies in rosacea with reference to all the available literature.This systematic review demonstrates the quality of evidence to support any recommendation on LLBT in rosacea is low-to-moderate. Among all the available devices, PDL holds the most robust evidence. Treatments options should be tailored for each specific clinical scenario as it is unlike that single modality results in complete resolution. Platforms that include two or more devices and combined therapies with topical agents are suitable and they warrant further investigations.
Mohs micrographic surgery, fixed-tissue technique, for excision of nasal melanoma provides three important benefits: 1) assurance of eradication of the main mass along with its “silent” contiguous outgrowths, 2) safe management of non-contiguous satellites too small to be visible initially, and 3) safe sparing of maximal amounts of surrounding normal tissues. These benefits are achieved because all incisions are through
