Localized Myxoedematous lichen: A rare subtype of cutaneous Mucinosis clinical and dermoscopic features

Abstract

Cutaneous mucinoses, also called lichen myxoedematosus, are a group of diseases characterized by mucin deposit on the skin. They may be associated to systemic diseases or be primary ones. The discrete papular form (DPLM) is a very rare entity that is located exclusively in the skin and is not associated to any systemic disease. We present the case of a 67-year-old healthy woman who had multiple discrete papillae of normal skin color with a smooth surface at the neck, the nape and the upper part of the trunk and whose histological study confirmed an (DPLM), and we also report the dermoscopic aspect of this entity not previously found in the literature
