Nail Deformity in a Young Girl

A healthy 9-year-old girl presented with cosmetic concerns regarding fingernail changes for the preceding 9  months. There was no history of any associated pruritic skin eruptions, oral mucosal involvement, hair loss, or any preceding trauma. Examination revealed nail plate thinning, longitudinal ridging, distal splitting, and characteristic dorsal pterygium involving the fingernails (Figure, A). Other m ucocutaneous areas were spared. Dermoscopy (DermLite DL4, 10×, polarized mode) showed thinned out nail plate, longitudinal ridging, dorsal pterygium with elongated capillaries, and the pup tent sign (nail plate separated from the nail bed with sloping lateral edges) (Figure, B).
