Irritated Nevus and Meyerson’s Nevus
Benign melanocytic nevi exhibit a wide spectrum of clinical, dermoscopic, and histopathological appearances. Most of them are histopathologically banal. There is, however, a percentage which show one or more unusual clinical features and require more attention. Included among these are: (a) the irritated melanocytic nevus including the mechanically traumatized nevus with one special recently described variant, namely, the targetoid hemosiderotic nevus ; and (b) the UV-irradiated nevus. A special variant is (c) Meyerson’s nevus, which is surrounded by a halo of eczema in the same way that a halo of depigmentation surrounds a Sutton nevus .
