Antigen Background
Anaplastic large cell lymphoma (ALCL) is usually composed of large
pleomorphic cells which are reported to express CD30 antigen and the
epithelial membrane antigen (EMA). These tumor cells tend to occur in
younger individuals and may be associated with cutaneous and extranodal
involvement. A proportion of these cases contain a chromosomal
translocation t(2;5) (p23; q35). This results in a hybrid gene encoding part of
the nucleophosmin (NPM) gene joined to the cytoplasmic domain of the
anaplastic lymphoma kinase (ALK) gene, giving rise to the protein, p80. Large
cell lymphomas account for approximately 25 percent of all non-Hodgkin's
lymphomas in children and young adults, of which one third carries the NPMALK gene translocation.
