A 33 year old man with dysplastic naevus syndrome presented with a two week history of pruritus and inflammation affecting a pigmented naevus on his thorax. Examination showed an erythematous scaly eruption encircling the pre-existing naevus. People with dysplastic naevus syndrome are at higher risk of malignant melanoma. Moreover, pruritus, crusting, or inflammation involving a naevus are important warning signs for melanoma and should prompt an urgent consultation. However, Meyerson’s naevus was diagnosed. This benign condition, in which a naevus triggers a halo of eczematous inflammation, is distinct from dysplastic naevus syndrome. In this case, the inflammation resolved with topical steroid treatment.
