Proliferative Nodules in Congenital Nevi

  • Guido Massi
  • Philip E. Leboit


One or more large nodules may occasionally appear in a congenital nevus. As a rule, the nevus is of the “large” or “giant” type and the patient is very young. However, similar nodules can be rarely found in smaller congenital nevi and analogues can even appear in adulthood. The nodules may protrude above the surface of the congenital nevus or can be situated deeply within the lesion. The common denominator of the nevi in which proliferative nodules occur seems to be their depth rather than their diameter. In most cases, the deep reticular dermis and subcutaneous septa contain cords and strands of small, round melanocytes.
