Meyerson Nevus Imitando Melanoma Maligno Meyerson Nevus Mimicking Malignant Melanoma

Resumo

Meyerson nevus represents an uncommon clinical and histological variation of melanocytic lesions that is characterized by an eczematous halo surrounding a melanocytic nevus.¹
It was first reported by Meyerson and it typically clears spontaneously or resolves with topical corticotherapy.²
We report the case of an atypical Meyerson nevus in which, despite intense pruritus, both an eczematous eruption and dermoscopic patterns imputable to a melanocytic lesion were lacking.
