Summary

This study looked at 81 adults with either palmoplantar psoriasis or palmoplantar eczema, two skin conditions that can look very similar on the palms and soles. Researchers used two special camera techniques—polarized dermoscopy and ultraviolet-induced fluorescence dermoscopy—to see if they could spot differences between the two diseases. The goal is to help doctors make a faster, non-invasive diagnosis without needing a skin biopsy.
