Clear cell acanthoma – http://id.who.int/icd/entity/1582724858

Clear cell acanthoma manifests as a firm, brown-red, dome-shaped nodule or papule with a predilection for the lower legs. Histopathologically it is characterised by sharply demarcated psoriasiform epidermal hyperplasia containing glycogen-rich keratinocytes with pale-staining cytoplasm. The dermoscopic appearance of clear cell acanthoma is very characteristic with dotted blood vessels are arranged as "pearls on a string".
