In this study, we report a rare case of congenital PTBN involving the right palm since birth. A 10-year-old girl presented to our department with plaque in her right palm accompanied by a tingling sensation for 1 month. Histochemical analysis indicated a heavily pigmented melanocyte proliferation in the dermis, subcutis, and fascia. The patient was diagnosed with congenital PTBN and underwent surgical excision. No recurrence was observed during a 5-year follow-up.<\/jats:p>","DOI":"10.3389\/fped.2025.1626876","type":"journal-article","created":{"date-parts":[[2026,1,7]],"date-time":"2026-01-07T06:54:20Z","timestamp":1767768860000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Congenital
