A case of dermatopathia pigmentosa reticularis

Dermatopathia pigmentosa reticularis (DPR) is a very rare disorder with the diagnostic triad of generalized reticulate hyperpigmentation, noncicatricial alopecia, and onychodystrophy. Many other dermatologic findings have been associated with this triad, including adermatoglyphia, hypohidrosis or hyperhidrosis, palmoplantar hyperkeratosis, and nonscarring blisters on the dorsa of the hands and feet. The mode of inheritance is unclear but may be autosomally dominant. To our knowledge, only 11 cases have been reported in the world, and none has previously been described in the Orient. We present a Korean patient with the typical features of the DPR triad, along with adermatoglyphia, hypohidrosis, and nonscarring blisters on the dorsa of the feet.
