[Malignant non-Hodgkin-lymphomas on lid, orbita and lacrimal sac (author's transl)].

Two personal observations on malignant non-Hodgkin lymphomas of the eye are presented, i.e., a lymphoplasmocytoid lymphoma (so-called immunocytoma) of the lid and orbita and a case of mixed centroblastic-centrocytic lymphoma of the lacrymal sac. The different histological findings are demonstrated. According to the lymphoma-classification by Lennert (Kiel), both the tumours belong to the group with a low degree of malignancy. No general synptoms could be found in the afflicted patients.
