Description
Madeleine Louise Kelly and colleagues report a scalp melanoma that announced itself by turning white hair brown, publishing the case in 2026. A 78-year-old man presented with a patch of light-brown hair on the crown amid otherwise white hair, decades after childhood scalp radiotherapy for ringworm. Examination found a tan pigmented patch with darker spots, and biopsy showed lentigo maligna, a melanoma in situ subtype.
Wide excision with skin grafting revealed a tiny invasive component limited to the upper dermis, and follow-up showed no recurrence. The case highlights hair repigmentation as a rare warning sign of melanoma and past scalp irradiation as a possible risk factor. Clinicians should weigh both when assessing new pigment changes on irradiated scalps.
