Follicular lymphoma – http://id.who.int/icd/entity/797822185
Follicular lymphoma (FL) is a neoplasm composed of follicle centre (germinal centre) B-cells (typically both centrocytes and centroblasts/large transformed cells), which usually has at least a partially follicular pattern. t(14;18) with BCL2 rearrangement is frequently observed. If diffuse areas of any size comprised predominantly or entirely of blastic cells are present in any case of follicular lymphoma, a diagnosis of diffuse large B-cell lymphoma is also made. Lymphomas composed of centro cytes and centroblasts with an entirely diffuse pattern in the sampled tissue may be included in this category.
