Mosaic disorders, which include epidermal nevus syndromes (ENS) such as nevus sebaceus, keratinocytic epidermal nevus, nevus comedonicus, and Becker’s nevus, have varied genetic factors that contribute to their development. These genomic discoveries are expanding rapidly and a recent review looked at advances in the genetic knowledge about these disorders and highlighted promising findings. The review …
Capillary malformations (CM) occur in a small percentage of children, and can be complicated by lymphatic, venous, arteriovenous anomalies, such as birthmarks and port wine stains, and/or soft-tissue or bone overgrowth that may result in differences in limb length. Complications might be present at birth or occur years later. Using data from a multicenter cohort …
Congenital melanocytic nevi (CMN), typically referred to as birthmarks, can be small, large, and giant. Concerns about CMN are twofold – the cosmetic appearance and its impact on quality of life and whether CMN may eventually develop into melanoma. Studies have shown varied risk as to whether they will develop into melanomas, but current research …
When the Fitzpatrick skin phototype classification was developed, the intention was to provide a standardized way to refer to differing Caucasian skin types. Originally developed to select the appropriate doses of ultraviolet A to treat psoriasis with PUVA therapy, the classification system was also used to gauge skin tolerance to sun exposure. Answers to questions about tanning …
Though many teens get stretch marks during adolescence, a certain subset of teenage boys end up with horizontal striae distensae (SD) of the lower back. These marks can be worrisome for parents because previous research has indicated that they may be a result of bacterial infection, a sign of metabolic disease, or associated with unmonitored steroid …
Much attention is paid to avoiding UV exposure during leisure time to prevent cutaneous squamous cell carcinoma (SCC), but a recent study looked at whether outdoor workers might be even more at risk. The study was a multi-center population-based case–control study that applied UV-exposure estimation methods to examine the association between occupational and nonoccupational UV …
