Mucinous nevus

From Wikipedia, the free encyclopedia

Mucinous nevus
Other namesNevus mucinosus
SpecialtyDermatology

Mucinous nevus is a rare cutaneous condition characterized by hamartoma that can be congenital or acquired.[1] Mucinous nevus presents as multiple skin-coloured or brown asymptomatic papules or plaques. Mucinous nevus is diagnosed based of histological features. Treatment is not needed.

Signs and symptoms

Mucinous nevus appears as several skin-coloured to brownish papules 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]

Causes

There has been reports of familial mucinous nevus, however there have been no reports of genetic abnormalities.[5][4]

Diagnosis

Histologically, diffuse band-like mucin deposits in the uppermost layer of the dermis are indicative of mucinous nevus.[6] Hyaluronic acid is assumed to be the component of mucin since it reacts positively with alcian blue at pH 2.5 but does not at pH 0.5.[7][8]

Treatment

Mucinous nevi are benign and don't need to be treated other than for aesthetic reasons.[2] Carbon dioxide laser therapy, scalpel dermabrasion, and surgical excision are treatment options.[9]
