Figure 2: Histopathology of pigmented lesion on axilla. (a) Tumor cells are arising from the basal cell layer exhibiting peripheral palisading. Pigment laden macrophages can be seen in the dermis (H&E ×200); (b) Tumor cells with hyperchromatic nuclei, inconspicuous nucleoli, and scant amount of cytoplasm (H&E ×400). (c) Tumor cells strongly and diffusely positive for CK5/6 immunostain (immunoperoxidase ×200)
