[Lymphoplasmocytoid immunocytoma of the rectum (author's transl)]

A case report is given of a patient with a lymphatic tumor of the rectum, which was diagnosed by rectoscopy and which was classified histologically as a lymphoplasmocytoid immunocytoma according to the new Kiel nomenclature of Non-Hodgkin-lymphomas. Clinical symptomatology does not differ from symptoms of other tumors of the colon; endoscopy, cytology and histology are important for diagnosis, since the therapy of choice may be radiotherapy or cytostatic therapy depending upon stage and extent of the tumor.
