title: [Malt digestive system lymphomas and alpha heavy chain diseases. Histological and immunohistochemical study. Apropos of 3 cases].
abstract: Malt lymphomas are lymphomas developed from mucosa associated lymphoid tissue and may involve many sites such as the gastrointestinal tract, salivary glands, thyroid gland lung, breast and female genital tract. Histologically, their diagnosis is based upon the existence of four elements: centrocyte-like cells that are responsible for lymphoepithelial lesions that are sometimes very difficult to demonstrate reactive or residual follicles and plasma cells. We study 2 cases of gastric Malt lymphoma and one of alpha heavy chain disease involving the small intestine and the stomach and we try to define the common features of Malt lymphoma, alpha chain disease and non-secretary IPSID, which all present the clinical tetralogy mentioned above.
