ALK-positive large B-cell lymphoma
Anaplastic lymphoma kinase (ALK)-positive diffuse large B-cell lymphoma is a very rare variant of diffuse large B-cell lymphoma (DLBCL) mainly affecting middle-aged immunocompetent men and characterized by a consistent primary involvement of lymph nodes (mainly in the cervical and mediastinum lymph nodes) and with infrequent extra nodal involvement of the bone marrow and other extra-nodal sites (head and neck region, liver, spleen, and gastrointestinal tract). It has an aggressive disease course, and is associated with a poor prognosis.
