Abstract
Meyerson’s nevus (MN) is a term describing melanocytic nevus with a surrounding symmetrical halo of erythema and scaling. It most commonly presents as an itchy or asymptomatic lesion on the trunk or proximal part of the upper limbs in young individuals, with male predominance. The underlying cause of MN has not been explained. Histopathologically, the features of associated spongiotic reactions are observed, including spongiosis, acanthosis, parakeratosis, lymphocytic exocytosis, as well as intraepidermal spongiotic vesicles. Dermoscopy of this phenomenon was rarely reported. No dermoscopic report on amelanotic Meyerson’s nevus has been found. The study reports a 29-year-old woman (phototype II), with a previous history of papillary thyroid carcinoma, who presented with an amelanotic nodule on her right arm. The patient reported enlargement of the lesion within the previous several weeks. Dermoscopy showed the presence of dotted, glomerular and short linear irregular vessels over a pink-yellowish background as well as the presence of a white scale. Due to the history of a growing, amelanotic lesion with polymorphic vessels, an excisional biopsy was performed. Based on histopathology the diagnosis of Meyerson’s nevus was made.
