Stucco keratosis is an acral keratotic papule that occurs on the distal portions of the lower extremities and is acquired during the advance of years. When the lesion is removed, a peripheral collarette of scale remains without bleeding. Histopathological study shows epidermal hyperplasia of the "church-spire" pattern, accompanied by little or no dermal infiltrate. This common lesion, which is usually asymptomatic, probably goes unrecognized, because of its banal and inconspicuous nature.
