Figure 1: (a) There was invasive erythematous plaque in the right ear and right cheek. (b) A skin biopsy from the lower jaw revealed diffuse sheets of small cytoplasmic cells with poor cytoplasm throughout the dermis and with minimal involvement of the overlying epidermis (H&E, 10 ×). (c) Atypical cells expressed CD4 (40 ×). (d) Atypical cells expressed CD56 (40 ×). (e) c-kit-negative atypical cells (40 ×) (f) Flow cytometry analysis of the tumor. (g) Transmission electron microscopy (TEM) showed mature plasmacytoid dendritic cells
