Blue nevi are usually solitary but may rarely appear grouped in an agminated pattern. Clinically, they present as a group of multiple blue nevi in a circumscribed skin area smaller than 10 cm in diameter.1 The skin between the papules may not be discolored and may show a speckled or uniform blue-black or brown pigmentation.1 We report a case of agminated blue nevus.
