Abstract

1. Two familial cases of dyschromatosis universalis hereditaria are reported.
2. In the same family the occurrence of similar dermatoses is noted in five generations.
3. Unexposed parts of the body is as strongly affected as the exposed area. And even the palm and sole are involved.
4. The pigmentary disturbance is caused by genotype with epistases of some other factors than photosensitivity.
5. Thus the relationship with dyschromatosis symmetrica hereditaria is rejected in spite of clinical resemblance.
