Although the pathogenesis of PAD is unknown, PAD may be associated with mutations in ATP2C1 and ATP2A2 genes. Here, we report on an 18-year-old female patient with multiple gray-white flat papules in the anogenital area. Skin biopsy revealed hyperkeratosis of the epidermis, acantholysis, formation of fissures or lacunae, and disappearance of desmosomes. Whole exon sequencing (WES) of the patient indicated mutations in the ATP2C1 gene.Keywords: Papular acantholytic dyskeratosis, Whole exon sequencing, ATP2C1 |
