Mucinous nevus is a rare cutaneous condition characterized byhamartoma that can be congenital or acquired.[1] Mucinous nevus presents as multiple skin-coloured or brown asymptomaticpapules or plaques. Mucinous nevus is diagnosed based of histological features. Treatment is not needed.
Mucinous nevus appears as several skin-coloured to brownishpapules or plaques that are asymptomatic; the individual lesions merge and expand to form a unilateral or zosteriform feature that is verrucous or nevoid.[2][3] It normally starts to develop in early adulthood or from birth.[4] The main location is the trunk, which includes the back.[2][5]
Histologically, diffuse band-likemucin deposits in the uppermost layer of thedermis are indicative of mucinous nevus.[6]Hyaluronic acid is assumed to be the component ofmucin since it reacts positively withalcian blue at pH 2.5 but does not at pH 0.5.[7][8]
