Mantle Cell Lymphoma With Mantle Zone Growth Pattern.

abstract：:Because of the demonstrated efficacy of Leu-M1 as a discriminant between malignant epithelioid mesothelioma (MEM) and adenocarcinomas involving the serosal surfaces (ACSs), the authors assessed the reactivities of related "myelomonocytic" antigens in this context. Paraffin sections from 41 MEMs and 43 ACSs (pulmonary,...
