[Cutaneous manifestations of angio-immunoblastic lymphadenopathy]

The authors report four cases of angio-immunoblastic lymphadenopathy, presenting with cutaneous lesions: these have a tumoral presentation in two cases while in the other two, the polymorphic aspect of the cutaneous lesions is reminiscent of a toxidermic eruption. In contrast to the relative clinical polymorphism, the pathological findings are monomorphic, i.e., in all cases, there was a vascular proliferation together with a more or less dense cellular infiltrate consisting of cells indistinguishable from those involving the abnormal lymph nodes.
