Five cases of erythema dyschromicum perstans which seem to be the first cases in Korea are described.
They are healthy subjects with moderately pigmented skin.
Numerous gray-blue macules are seen on the covered part of the body in two patients, but dark brownish macules in -other three patients. Histologic findings reveal the characteristic features of hydropic degeneration of the basal cell layer ´of the epidermis, perivascular infiltrates of lymphocytes and histiocytes and melanin-laden macrophages in the corium in four patients, however, merely pigmentary incontinence into the corium in one patient.
We think that there are some problems in cases which show the chracteristic features of erythema dyschromicum perstans histologically but do, not have peculiar clinical features, e.g. color of the lesion, especially in Oriental.
In this respect, though there may be down for much discussion in three cases which have not typical color of the lesion, we report these cases with typical two cases under the name of erythema dyschromium perstans in order to accumulate more knowledge of these problems.
