A Case of Blue Nevus Presented as Multiple Macules and Patches / 대한피부과학회지

ABSTRACT

A 32-year-old woman had multiple bluish macules and patches on her right back. They had gradually increased in number and size since they had first appeared at age 27 years. About 35 blue or blue-grey macules and patches measuring 1~40 mm in diameter were scattered on her back. Histologic examination showed hyperkeratosis and basal hypermelanosis in the epidermis and scattered spindle-shaped cells containing melanin granules in upper and middle dermis. Most of the dermal melanocytes were arranged parallel to the epidermis. We report a case of blue nevus on the back which presented as multiple scattered bluish macules and patches.
