CPC-CASE : (N0A6-1) A 37 year old man found a dark brown
lesion on the skin of his face, just in front of the ear. He ignored the lesion, even though it became larger and started to bleed. Then he began to develop many more spots on his face and neck. At this point, he went to the doctor who did a biopsy and gave him some treatment. However, he died 8 months later.
