Two-Year Follow-Up of Ectodermal Dysplasia-Syndactyly Syndrome 1 in a Palestinian Child Successfully Treated With Topical Minoxidil and Tretinoin: A Case Report

This case report describes a 5.5-year-old Palestinian girl with Ectodermal Dysplasia-Syndactyly Syndrome 1 (EDSS1), characterized by hypotrichosis, dental anomalies, nail hypoplasia, palmoplantar keratoderma, and syndactyly. The girl was treated with off-label topical minoxidil 2% and tretinoin 0.025%, resulting in increased hair density and thickness after 3 months, with sustained improvement over a 2-year follow-up. The treatment was well-tolerated, and the case suggests a potential role for topical retinoids in managing hypotrichosis in EDSS1, although further studies are needed to validate these findings.
