A 71-year-old woman with a pigmented nail bed, which persisted after trauma.

A 71-year-old woman presented in our out-patients department with pigmentation of the nail bed of her left large toe, which had persisted after a trauma two years earlier. An inconclusive biopsy showed melanoma in situ. The lesion was excised with amputation of the big toe at the IP-joint and closed primarily. The pathological diagnosis was melanoma in situ and lentigo maligna. The lesion had been radically excised.
