The guideline was developed by a multidisciplinary expert group and is based on the available literature as well as empirical experience in the diagnosis and treatment of ingrown toenails and pincer nails. Its aim is to define diagnostic criteria, preventive measures, and therapeutic approaches. For ingrown nails, the guideline presents definitions, a clinical classification (grades I\u2013III), and corresponding treatment recommendations. Conservative measures, podiatric interventions, and patient\u2010centered prevention are emphasized, while surgical procedures \u2013 particularly minimally invasive techniques with partial matrix excision \u2013 are recommended for therapy\u2010resistant or severe cases. For pincer nails, definitions, clinical morphology, and potential therapeutic options are described; due to limited data, individualized management is emphasized. The guideline aims to standardize care, reduce treatment variability, and promote a consistent, interdisciplinary approach.<\/jats:p>","DOI":"10.1111\/ddg.70442x","type":"journal-article","created":{"date-parts":[[2026,9,24]],"date-time":"2026-09-24T06:58:38Z","timestamp":1790233118000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["S1 Guideline: Management of ingrown nails (Unguis incarnatus, Onychocryptosis) and pincer nails (Unguis in turriculo)"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1249-8921","authenticated-orcid":false,"given":"Antonia","family":"Pennitz","sequence":"first","affiliation":[{"name":"Charit\u00e9 \u2013 University Medical Center Berlin, corporate member of Freie Universit\u00e4t Berlin and Humboldt\u2010Universit\u00e4t zu Berlin Department of Dermatology, Venereology and Allergology Division of Evidence\u2010Based Medicine (dEBM)  Berlin Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Galina","family":"Balakirski","sequence":"additional","affiliation":[{"name":"Center for Dermatology, Allergology and Dermatologic Surgery, Helios University Hospital Wuppertal, University of Witten\/Herdecke  Wuppertal Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oliver","family":"Gahn\u2010Schuster","sequence":"additional","affiliation":[{"name":"Podologikum am Bertholdplatz  Baden\u2010Baden Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steffen","family":"Gass","sequence":"additional","affiliation":[{"name":"Joint Dermatology Office Dr. med.
