Summary

This completed registry study in Japan looked at how doctors treat palmoplantar pustulosis (PPP), a skin condition causing pus-filled blisters on hands and feet. Researchers collected data from 276 patients' medical records and clinic visits to understand which treatments are used and how long patients stay on them. No new treatment was tested; the goal was to describe real-world care patterns.
