A case of cutaneous lymphocytic infiltration with large numbers of plasmacytoid T cells (PTC) is reported. Lectin staining and immunohistological analysis revealed that PTC and cutaneous dendritic cells showed a similar expression of concanavalin A, LN2, and MT1. Moreover, differences in TAL 1B5 and S‐100 expression were noted. From these findings we suggest that PTC may occur in the skin as a component of the skin‐associated lymphoid tissue.
