Epithelial membrane antigen and factor VIII are strongly suggestive for the diagnosis of MM; mesothelioma-related markers include calretinin, thrombomodulin, CK5/6 (pleural), WT1 (Wilms tumour antibody), D2-40, CK7 (tunica vaginalis) [120, 162, 188, 198], CD20 +, and calretinin + [196, 200]. The gene discussed is KRT7; the disease is mesothelioma.
