    Anywhere...brain, lungs, lymph nodes, et.c
  18. What is an acral melanoma?
    Nail melanoma
  19. How does malignant melanoma grow?
    • Horizontally within the epidermis
    • Vertically within the dermis
  20. What type of skin disease grown horizontally in the epidermis and vertically in the dermis?
    Malignant melanoma
  21. How is probability of metastases determined in malignant melanoma?
    by the length of vertical growth into the dermis
  22. What are the meninges?
