Meyerson’s naevus

A Meyerson's naevus is a benign melanocytic naevus surrounded by eczematous changes.

This chapter is set out as follows:

• Most commonly affects young patients
• It is nearly three times as common in males compared to females
• Most lesions are itchy
• While it can arise in patients with a history of eczema, most patients do not have an atopic history

Distribution

• Usually solitary, but can be multiple
• The trunk is the most common site, although any site can be affected

Morphology

• A centrally positioned naevus surrounded by a red, dry or blistered rash

• The eczema resolves spontaneously or with a topical steroid, usually over a few weeks, leaving a normal looking benign melanocytic naevus - if the inflammation does not settle refer on an urgent skin cancer pathway as the differential would then include an inflammatory reaction to melanoma
