Multiple agminated spindle cell nevi: Unique clinical presentation and review

Agminated acquired melanocytic nevi of the common and dysplastic type

“…Pigmented lesions that have been described in the literature as agminated include blue nevi, 12,13 multiple lentigines, 14 Spitz nevi, [15][16][17][18][19] congenital melanocytic nevi, 5,20 acquired melanocytic nevi, 21 and lesions within nevi spili. 22,23 The above-mentioned pigmented lesions can be ruled out in our patients based on the time course and clinical appearance.…”
