General and Systemic Histopathology, C601&C602
    Slide 150: Intradermal Nevus of Skin
    Again, it's fairly easy to spot the lesion just by looking at the slide before going to your microscope.  You will see a number of hair shafts and sebaceous glands, some of which are bit deformed due to the presence of the nevus.  Even so, this lesion is still benign.

    See this slide with the virtual microscope.

    In this case you will see clusters and theques of benign nevus cells in the dermis. You should be able to see there is "maturation" of the cells as one goes from the surface of the lesion to the base. You will find no mitosis and there is no cytoatypia of the nevus cells. How would you distinguish this lesion from a malignant melanoma?
