[Non-Hodgkin's lymphoma with primary osseous manifestation, from the files of the Bone Tumor Registry of Westphalia].
30 cases of non-Hodgkin-lymphoma with primary bone manifestation were selected from the files of the Bone Tumor Registry of Westfalia from 1975 until 1992. Clinical data and radiologic aspects were evaluated. 60% of the lesions were localized within the long bones (femur 10, humerus 6, tibia 2). The lymphomas were classified based on paraffin-embedded material in combination with immunohistochemical findings according to the updated Kiel-classification. 29 B-cell lymphomas and one T-cell lymphoma of medium-sized pleomorphic type were found. 5 B-cell lymphomas were of low and 23 of high malignancy. Almost 50% of the tumors were of centroblastic type. The Kiel-classification was not applicable for one lymphoma, 3 others could not be subclassified because of shrinking artefacts. Prognosis in patients with localized disease (9 cases) was favorable, whereas only 25% of patients with generalized disease (12/cases) survived for 3 years or longer.
