Keratoacanthoma
Keratoacanthoma
Keratoacanthomas are rapidly growing, red (erythematous), dome shaped bumps (papules/nodules) with central craters. Occasionally, these will disappear spontaneously (involute). Often, they are treated to avoid further involvement or destruction of underlying tissue. They are of concern because of the similarity to squamous cell cancer.
