Vázquez-Osorio). Dermatologic examination revealed a brownish oval lesion measuring 1 cm in diameter, with a desquamating erythematous surface and a peripheral hypopigmented halo of 4 mm (Fig. 1). The Meyerson phenomenon refers to an eczematous reaction arising on a previous, typically melanocytic skin lesion. It is a benign and usually asymptomatic phenomenon that is uncommon in children. The halo or Sutton nevus is a benign, typically acquired melanocytic nevus with a peripheral achromic halo; it is common in children. Coexistence of the Meyerson phenomenon and halo nevus in distinct lesions in a single patient has been reported, as the progression of a Meyerson nevus to a halo nevus, and vice versa. However, there are no previous reports of the simultaneous presence of both phenomena in a single nevus. We have presented an example of a melanocytic lesion in which the Sutton and Meyerson phenomena (SU-ME phenomenon) coexisted.
