Cutaneous squamous cell carcinoma	pain	erythema		indurated	hyperkeratotic	increased size								skin biopsy	60 percent of squamous cell carcinomas occur at the site of a previous actinic keratosis
Actinic keratoses	pain			hyperkeratosis	erythema	less pigmentation, and tend to be somewhat smaller in size.								Skin biopsy
Merkel cell carcinoma				Starts on areas of skin exposed to the sun	Single pink, red, or purple shiny bump	Painless								Skin biopsy	blue-red, dome-shaped nodule
Prurigo nodules
