Electron Microscopy (EM)- Be able to identify specific images on EM:
- Dermoepidermal junction (specifically lamina lucida, lamina densa, hemidesmosomes) (Figure 9.5A)
- Sezary cell (Figure 9.6B)
- Birbeck granules of Langerhans cell (Figures 9.5B, 9.6A)
- Others (less often tested): mast cell (Figure 9.6C), Merkel cell, melanocyte with melanosomes
