Abstract:
We observed three patients who showed widespread macular ashy-colored eruptions. They fit clinically and histopathologically with the typical erythema dyschromicum perstans (ashy dermatosis). Erythoma dyschromicum perstans is a peculiar pigmented condition of unknown etiology characterized by persistent ashy-gray colored macule, refractory to any modality. All of them have similar skin lesions which are multiple, variable sized oval-shaped, ash-colored macular eruption on the trunk and extremities. Histologic findings of 2 patients reveal the characteristic feature of focal hydropic degeneration of the basal cell layer of the epidermis, perivascular infiltrates of lymphocytes and histiocytes and melanin-laden macrophages in the corium, however, merely pigmentary incontinence into the corium in 1 patient. Literatures are briefly reviewed.
