An 83-year-old man complains that for the last few weeks he has had a bleeding lesion on his chest that seems to be growing rapidly. The lesion is shown below. What is the single most likely diagnosis?
This is a Squamous cell carcinoma. Sun-exposed skin in areas such as the head, neck, hands, and arms represent other typical sites of involvement. Bleeding, rapid growth and irregular surface differentiate from a seborrhoeic keratosis or wa. Basal cell carcinoma has a rolled edge, shows central ulceration and a pearly rolled telangiectatic tumor border.
