Clinical Report: Effective Use of Topical Simvastatin in a 2-Year-Old
Overview
This case study reports improvement in a 2-year-old girl with keratin 16-related palmoplantar epidermal differentiation disorder following treatment with topical simvastatin. The therapy was well-tolerated, with no adverse effects noted.
