Dermatopathia Pigmentosa Reticularis: Report of a New Cases and Literature Review.

Dermatopathia pigmentosa reticularis (DPR) is a very rare autosomal dominant ectodermal dysplasia caused by mutations in keratin 14 and characterized by the triad of generalized reticulate hyperpigmentation, nonscarring alopecia, and onychodystrophy. We report two Saudi brothers with DPR that had normal hair shafts, as assessed by scanning and transmission electron microscopy.
