ALK and anaplastic large cell lymphoma: Since there could not be an ALK- ALCL without ALK, one could say that the discovery of this lymphoma technically did not occur until 1994 when Stephan Morris, Thomas Look and colleagues at that time at Saint Jude Children’s Hospital in Memphis, TN, U.S., discovered the genes involved in the translocation t(2;5)(p23;q35) and recognized a novel tyrosine kinase in chromosome 2 that was called anaplastic lymphoma kinase (ALK) [9].
