Nevus anemicus: An island of sparing in the setting of drug-induced hypersensitivity

Nevus anemicus (NA) is an uncommon congenital finding characterized by a discrete area of hypopigmentation that remains stable in size throughout life. To our knowledge, generalized cutaneous eruption sparing NA in a mosaic fashion has never been reported in the literature. We report a case of erythrodermic drug-induced hypersensitivity syndrome (DIHS) in the setting of human herpes 6 virus (HHV-6) viremia, sparing NA.
