Extranodal involvement of de novo CD5⁺DLBCL, CD5⁻ DLBCL, and cyclin D1⁺ MCL.

In de novo CD5⁺ DLBCL (▪), the incidence of bone marrow involvement was higher than that of CD5⁻ DLBCL (■) and lower than that of cyclin D1⁺ MCL (░). Hepatomegaly and splenomegaly occurred more frequently in de novo CD5⁺DLBCL than in CD5⁻ DLBCL. Gastrointestinal involvement occurred less frequently than in either CD5⁻ DLBCL or cyclin D1⁺ MCL. BM, bone marrow; GI, gastrointestinal.
