ALK and anaplastic large cell lymphoma: Despite the revision of the initial pathology samples (lymph node and bone marrow) taken at another institution indicating that patient initially also had PTCL-, NOS- or ALK-negative ALCL, achieving a remission of five years without any treatment for such an aggressive disease undermines this claim and we can conclude that it is only hypothesis since both Figure 1 and Figure 3 histologically support the diagnosis of HL.
