title: B-cell markers in malignant B-cell lymphoma with scleroderma-like manifestation.
abstract: A case is described of malignant B-cell lymphoma with scleroderma-like manifestation. Using different monoclonals as B-cell markers the tumor appeared to be positive for surface immunoglobulins (SmIg) and for B2-antigen, but negative for intracytoplasmic immunoglobulin (CIg), BA2- and FMC7-antigens. Therefore, the tumor could be determined as a highly differentiated Sm-positive early B-cell type of B-cell lymphoma. In this clinically rare manifestation of cutaneous B-cell lymphoma aspects of the cell morphology and of cellular mediated immunity are briefly discussed.
