Abstract:
Plaque-type blue nevus is a rare type of blue nevus, which shows numerous macules and papules within a circumscribed area. Histopathologically, it is reported to be common or cellular. A 24-year-old female presented with a 10.5x8.6 cm blue-black plaque on the right shoulder, which had existed since birth, and was characterized by multiple confluent or grouped blue-black macules and papules with intervening areas of blue discoloration. Histopathologic examination showed irregular bundles of numerous, greatly elongated, grouped, heavily melanin-laden melanocytes with long, branching dendritic processes in the reticular dermis. Numerous melanophages were intermingled with melanocytes. We, herein, report a case of plaque-type blue nevus with histopathologic finding of common blue nevus.
