Dermoscopic findings in umbilical granuloma are vascular polymorphism comprised of linear irregular and arborizing vessels with structureless areas distributed over a milky-red background. The increase of angiogenesis and neovascularization is represented by the linear irregular and arborizing vessels. Structureless areas over an irregularly milky-red background are originated by the proliferation of vascular endothelial cells and fibroblasts, with capillary and granulation tissue formation. Pediatric Dermatology ANCER-ARELLANO Et AL.Dermoscopy may be useful for the diagnosis; however, further dermoscopic descriptions of the differential diagnosis are needed since these entities have other pathophysiology and different dermoscopic features. Silver nitrate is considered the first line therapy, and our patient had an excellent outcome. 2,5 In summary, dermoscopic features of UG include a vascular polymorphism comprised of linear irregular and arborizing vessels irregularly distributed over a structureless area with milky-red background. This dermoscopic pattern corresponds with the proliferation of vascular endothelial cells, angiogenesis, and the excess of granulation tissue present in the UG. keywords neonatal, neoplasms-benign O RCI D Jesus Ancer-Arellano https://orcid.org/0000-0003-0033-7212 Cesar D.

• Autoimmune diseases have an unclear etiology and complex diagnosis, and their treatment is challenging. • The etiology of frontal fibrosing alopecia remains unclear; nonetheless, its association with diseases such as vitiligo and thyroid disorders suggests an underlying autoimmune mechanism. Novel Insights • Understanding the phenomena of co-localization in autoimmune cutaneous diseases alongside frontal fibrosing alopecia still needs further research. • JAK/STAT inhibitors target a common immunological pathway and might be a potentially effective treatment for patients with multiple autoinflammatory skin diseases.
