Daniel! Please look up Blood 1994 Mar 15;83(6):1558-62 The immunophenotype of splenic lymphoma with villous lymphocytes and its relevance to the differential diagnosis with other B-cell disorders. Matutes E, Morilla R, Owusu-Ankomah K, Houlihan A, Catovsky D and several other articles. Both from the literature and our own experience there are rare cases that are CD5+ and correlate with the morphological diagnosis of SLVL.
