Abstract: Objective To report a case of lymphomatoid papulosis(LyP)followed by mycosis fun-goides(MF)during his 27 years course and determine whether these diseases are clonally related.Methods Characteristics of clinicopathology and immunophenotype of skin tissues of different phases of the patients were compared.Simultaneously,clonal T-cell receptor gene rearrangement of skin lesion tissues and blood specimens were detected by means of polymerase chain reaction and Southern blot analysis.Results A distinctc clinisal and pathological feature was shown in this case df LyP flowed by MF.The proliferating lymphocytes in LyP and MF were mature T helper lymphocytes,and with same T-cell clone.Conclusion LyP folloewd by MF displays a same T-cell clone.The clonal T-cell is irrelevant to the biological behavior of these diseases.
