Revisiting Palmoplantar Inflammatory Dermatoses (EADV-Sp 2026) - May 13, 2026 - Abstract #P0567; ID-574; "A retrospective outcomes study compared systemic therapy in refractory CHE, evaluating oral alitretinoin versus cyclosporine using 24-week response and drug survival. PPP similarly aligns with psoriasis-adjacent differentiation abnormalities while retaining distinctive clinicopathological features, whereas pompholyx and typical CHE more closely follow an eczematous differentiation pattern. Integrating IHC signatures with real-world systemic treatment outcomes provides a biologically grounded framework that may improve diagnostic precision and guide individualized systemic treatment selection in palmoplantar disease."
