[Congenital, self-healing reticulohistiocytosis]

The described skin condition is characterized by multiple congenital skin tumours and disseminated papules on the trunk, which regressed without therapy during the first two months of life. Apart from the skin, no other organs were involved. The histological examination showed a histiocytic infiltrate composed of cells with large, irregularly formed nuclei and partly opaque, foamy cytoplasm. Extravasation of erythrocytes was frequent. The skin disorder is similar to the congenital self-healing reticulohistocytosis of Hashimoto and Pritzker.
