[Crosti's dorsal reticulosis--a histiocytic lymphoma of a low degree of malignancy].

We report on the clinical and histological course of a lymphoma-like process similar to Crosti's dorsal reticulosis. Histological findings revealed a non-epidermotropic mixed cellular infiltration of histiocytes und T-lymphocytes with high and spontaneous cell destruction. We also observed high radiosensitivity.
