ABSTRACT

Agminated lentigines is characterized by numerous lentigines confined to a body segment, with a sharp demarcation at the midline. We report two cases of agminated lentigines, which were of asymmetric distribution on one side of the body, in a 16-year-old girl and a 27-year-old woman. The Lesions of the first patient were zosteriform, they involved the left side of the chest, axilla and shoulder. Lesions of the second case were involved on the left side of the abdomen and flank. Histologic examination showed hyperpigmentation of the basal layer, elongation of rete ridges, and an increased number of melanocytes.
