This study found that mosaic mutations in the CARD14 gene are linked to inflammatory linear verrucous epidermal naevus in two patients, who experienced significant improvement with the IL12/IL23 inhibitor Ustekinumab.

This narrative review explores the molecular mechanisms driving skin development and their role in skin diseases, emphasizing how disruptions in these pathways can lead to conditions like congenital disorders and cancers, potentially guiding new targeted therapies.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

This review examines the literature on the molecular and cellular makeup of the hair follicle niche and how it influences stem cell behavior during hair regeneration, but does not provide new experimental results.

This review discusses the physiological skin changes during pregnancy and reports no new clinical results, emphasizing the importance of distinguishing these changes from pathological conditions.

This review suggests that isotretinoin's effects on severe acne and various cancers may result from apoptosis, which might also explain its adverse effects through genetic variability.

This article reviews common hair growth abnormalities in children, emphasizing the importance of distinguishing normal development from potential signs of metabolic disorders and indicates no new clinical results.
