title: [Mystery of the swollen leg].
abstract: This case report demonstrates a 90-year-old female patient who had an amelanotic subungual melanoma of the right hallux. As usual non healing ulcer of the nail bed was initially misdiagnosed. Finally melanoma spread to the groin lymph nodes and induced lymphedema of the leg leading to the right diagnosis. Acral lesion requires early biopsy if any clinical uncertainty exists.
