Lymphomatoid papulosis: a model of lymphomagenesis.
Lymphomatoid papulosis (LyP) is a paradoxical cutaneous lymphoproliferative disorder. Clinically, it resembles the lesions of pityriasis lichenoides and behaves in a benign fashion in most patients. Histologically, it can mimic either Hodgkin's disease because of the presence of large atypical cells resembling Reed-Sternberg cells (type A LyP) or cutaneous T-cell lymphoma because of the presence of cerebriform lymphocytes (type B LyP). A review of this uncommon skin disease is presented here.
