  • Abstract
  • Look Inside

A case of this disease in a 15-year-old girl with small black points on the palms, confirmed histologically was reported.

Histologic specimen showed the eosinophilic, PAS-positive, homogeneous substances containing hemog-lobin studded almost at the same distance in the horny layer. No hyperkeratosis and no other abnormal finding in the epidermis and cutis could be revealed.

Almost all the homogeneous substances did not have any connection with the sweat duct in the horny layer, although some did. This finding indicates that this substance does not have an essential relationship with the sweat duct.

Although all reported cases had the disease on the sole, this disease on the palm is not unaccountable considering the anatomical similarity of the both sites.

Because all patients in the reported cases and the author's one were healthy and the eruption was temporary, it seemed that it was caused by the similar mechanism as the hemorrhagic friction blister. It may be formed by the movement of the tiny bleeding.
