| Abstract: | 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. |
