Clinics and Pathology

Disease

Extra-nodal Marginal Zone B-cell lymphoma (MZBCL) of mucosa-associated lymphoid tissue (MALT) type, also called MALT lymphoma

Note

MALT lymphomas without the t(3;14) are frequently associated with either a t(1;14)(p22;q32) ( BCL10 / IGH), a t(11;18)(q21;q21) ( API2 / MALT1, or a t(14;18)(q32;q21) (IGH/MALT1)

Epidemiology

9 cases detected to date

Clinics

MALT lymphoma is an indolent disease involving most often the stomach, the lung, the thyroid, the salivary gland, the orbit, and the skin, with a non random anatomic distribution according to the translocation. The t(3;14) is frequently found in MALT lymphomas of the thyroid, the orbit, and the skin.
