[Mantle cell lymphoma diagnosis].

Recent classifications of non-Hodgkin's lymphomas based on combination of morphologic, immunophenotypic, and cytogenetic criteria have individualized mantle cell lymphoma (MCL). This clinico-biological entity which accounts for 3 to 10% of all non-Hodgkin's lymphomas, now appears to be a biological and therapeutic model for the understanding and treatment of hematologic malignancies. The present study consisting of two cases of MCL collated at laboratory of hematology of Rabat Ibn Sina hospital.

[Mixed cryoglobulinemia with monoclonal IgA and biclonal IgM during hepatitis C virus infection].

Cryoglobulins are immunoglobulins that precipitate at low temperature and dissolve when warmed. According to Brouet, their classification relies upon the immunochemical study: type I comprises monoclonal immunoglobulins (IGG), when types II and III include both monoclonal and polyclonal components. During C hepatitis, the presence of a cryoglobulin, essentially made of mixed G-IGG and M-IGG, is a common feature with a prevalence of 40 to 80%.
