LEUKODERMA IN ASSOCIATION WITH GIANT CONGENITAL NEVI - REPORT OF 2 CASES

Two patients are presented in whom giant congenital nevi were associate wit hypopigmentation. One patient has had no associated melanoma. The second patient developed hypopigmentation years before a melanoma was excised, and increased hypopigmentation was noted years later without evidence of melanoma recurrence. While the mechanism for the development of the hypopigmentation noted in these two patients is uncertain, an immunologically mediated systemic process may be responsible.
