Description : Erythema palmare hereditarium is a benign condition that was first described by Lane
(1929). Erythema usually presents at birth and remains stable throughout life. Histology
shows dilated vessels in the entire dermis with inflammatory infiltrate. Capillaroscopy
reveals an increased number of capillary loops running parallel to the surface (summary
by Kluger and Guillot, 2010).;
