Abstract
|
|
|
We described a case of dyschromatosis Symmetrica hereditaria in a 20-year-old male patient who had had spotty hyperpigmentation mingled with patches of hypopigmentation on the lower extremities and abdomen since 5 years ago. In his family, the father and elder brother were also affected by this disease.
The histologic finding of the pigmented macule showed slight hyperkeratosis, absence of the granular layer, and dilatation of the blood vessels in the upper dermis. A marked increase of pigmentation in the basal cell layer of the epidermis was found on Fontana´s silver stain.
