Definition
A proliferative cutaneous disorder of the "indeterminate cells" (IC). The indeterminate cells are the dendritic cells of the skin that display histological, ultrastructural and antigenic features similar to those of Langerhans cells.

Most cases exhibit complete or partial spontaneous regression of lesions without recurrences.

Over prognosis is very good. Leukemia may be associated with this disease.
