Lentigo, Other Melanosis, and the Acquired Nevus

  • Chapter
  • First Online:
Melanocytic Lesions

Abstract

In this chapter, benign pigmented lesions associated with increased melanin pigment in basal keratinocytes and mild increase in the number of melanocytes such as lentigo, psoralen and ultraviolet A lentigo, solar lentigo, café au lait macule, ink-spot lentigo, mucosal melanotic macule, vulvar melanosis, and nevus spilus/speckled lentiginous nevus are discussed. In addition, the common acquired nevi are a phenomenon of the epidermis and papillary dermis, and they can present as junctional nevus, compound nevus, and dermal nevus.
