Atrichia With Papular Lesions Confirmed Via Genetic Testing: A Case Report

The document reports on a case of a 5-year-old girl diagnosed with Atrichia with Papular Lesions (APL), a rare and irreversible form of alopecia that manifests shortly after birth and is characterized by a complete loss of hair, keratotic papules, and milia-like cysts. The diagnosis was confirmed through genetic testing, which identified mutations in the hairless gene (HR) located on the zinc finger domain of chromosome 8p12, known to be associated with APL. This case underscores the importance of genetic testing in confirming the diagnosis of APL.
