Complications

  • Malignant melanoma may develop within speckled lentiginous nevus.
  • Predictors of the risk of malignant transformation of a speckled lentiginous nevus have yet to be determined. The surface area, the number of nevi within the speckled lentiginous nevus, and/or the presence of cytologic atypia may be factors that affect the potential for malignant transformation of a speckled lentiginous nevus.

Patient Education

  • Regular visits to a dermatologist and careful examination with the use of photography should be used for early recognition of atypical features within a speckled lentiginous nevus.
