Pigmented Actinic Keratosis
A variant of actinic keratosis is the pigmented actinic keratosis. As its name implies, it is more brown than red, but similar in biologic behavior to other actinic keratoses. These lesions resemble a freckle, seborrheic keratosis or a or melanoma in-situ called a lentigo maligna. These are important distinctions to make. A pigmented actinic keratosis that does not resolve after treatment with liquid nitrogen must be reassessed and biopsied if there is clinical suspicion of a melanoma.
