Extranodal oral lymphoma. Part I. A morphologic and immunoperoxidase study of 34 cases.
Thirty-four cases of oral lymphoma were classified by the Lukes-Collins system on the basis of morphology and immunoperoxidase staining. Ninety-seven percent of these were morphologically identified as B-cell neoplasms: 6% SCFCC, 9% LCFCC, 26% SNCFCC, 24% LNCFCC, 12% IBS, and 18% malignant plasma cell proliferations. Monoclonal immunoperoxidase staining for cytoplasmic immunoglobulin was positive in 41% of the cases overall, but 100% of the cases of immunoblastic sarcoma and malignant plasma cell lesions stained positively.
