Ashy Dermatosis in a Two-year-old Child: A Case Report and Mini-review.

Abstract

Ashy dermatosis, or erythema dyschromicum perstans, is characterized by acquired grey patches distributed on the face, neck, trunk, and extremities with an unknown pathophysiology. Herein, we report a case of ashy dermatosis in a two-year-old child, possibly caused by an infection, with eventual improvement within two years, absent any treatment. To our knowledge, this is the second report of ashy dermatosis in a patient under the age of three years, and the first under the age of two years that was followed-up in the English-language literature from 2000 to 2021. Although the eruptions showed eventual improvement without any treatment in our case, all cases do not improve spontaneously. Further research is necessary to differentiate cases that eventually improve from resistant ones and determine treatment options for resistant cases.
