A case of hair re-pigmentation from a scalp melanoma.

Hair re-pigmentation in adults is a rare phenomenon. We describe a 58-year-old woman who developed hair re-pigmentation on her vertex scalp as a marker of underlying melanoma. Histopathology revealed a nodular melanoma that was surrounding but not invading follicular epithelium. To our knowledge, there have only been 4 other previously published cases describing hair re-pigmentation in the setting of scalp melanoma. Focal hair re-pigmentation in adults should prompt a thorough evaluation for an underlying melanoma.
