Infantile hemangiomas (IHs) are the most common pediatric vascular tumors, although their genetic etiology is largely unknown. Congenital capillary malformations (CMs) are associated with known somatic pathogenic variants, including GNAQ, GNA11, PIK3CA, and PIK3R1. Co-occurrence of a facial CM such as port wine stain and IH is not associated with any recognized vascular anomaly syndromes and rarely reported in the literature.

Immunosuppression is a well-documented risk factor for skin cancer, as exemplified by the 65- to 250-fold higher squamous cell carcinoma risk, 10-fold higher basal cell carcinoma risk, and 0 to 8-fold higher melanoma risk in solid organ transplant recipients (SOTRs) receiving potent, prolonged courses of immunosuppressive therapies. Numerous immune system components have been shown to either suppress or promote tumor growth, and immunosuppressive drugs may have additional effects on proliferative pathways independent of the immune system. Thus, evaluation of the specific regimen by the dermatologist is key for assessing skin cancer risk in each patient.

Article Synopsis
  • Solid organ transplant recipients face an increased risk of skin cancer due to posttransplant immunosuppression, leading to specific screening practices.
  • The study reviews the risk of melanoma and nonmelanoma skin cancer linked to various immunosuppressants beyond those used post-transplant, including methotrexate, cyclophosphamide, and biologic agents.
  • It recommends regular skin cancer screening for certain non-transplant patients on these immunosuppressive therapies and provides guidance for safely managing treatment in high-risk individuals.

Dietary behavior can have a consequential and wide-ranging influence on human health. Intermittent fasting, which involves intermittent restriction in energy intake, has been shown to have beneficial cellular, physiological, and system-wide effects in animal and human studies. Despite the potential utility in preventing, slowing, and reversing disease processes, the clinical application of intermittent fasting remains limited.
