title: [Elastoma perforans serpigiosum].
abstract: After a survey of the literature a case of "elastoma perforans serpiginosum" - characteristic from the clinical and histological viewpoint - is discussed. Our findings reveal that it deals with an "elastica-degeneration" within a zone of inflammation. Its catabolic products are discharged as necrotic masses through the epithelium or the follicles to the outside. Despite of the imposing clinical appearance it is not primarily a keratosis. The massive proliferation is secondary. The "forceps-like" enclosure of necrotic masses by proliferating epithelium may stimulate  a space within the follicle. Aetiopathogenesis and therapy are discussed.
