[Epidermotropic reticulosis of the Woringer-Kolopp type (author's transl)].

A 46-year-old female, otherwise healthy, developed erythematous, pseudotumoral nodules, mainly on the hands; biopsies led to the diagnosis of Woringer-Kolopp disease. Anti-anergic chemotherapy with levamisole proved hazardous but, possibly, beneficial. Classification into benign localized, fatal generalized and intermediate disease is briefly commented upon. Differential diagnosis and tumor origin are discussed; while the Merkel cell hypothesis has been recently advanced strong analogies and slight discrepancies with mycosis fungoides advocate the T cell lymphoma theory.
