The mucinous nevus (MN) is a rare variant of connective tissue nevus of the proteoglycan type. The term “mucinous nevus” was proposed because of its nevoid appearance and characteristic pattern of mucin deposits in the papillary dermis.


Clinically mucinous nevus is composed of soft, skin-colored grouped papules and nodules forming a plaque or arranged in a linear, grouped or dermatomal distribution. Half are present at birth and the rest have onset by early adulthood. The back is the most common location [JAMA Derm 2014;150;1018].


No treatment is necessary. Surgical excision or laser may be considered for cosmesis.
