Nodular melanoma is the most rapidly growing and aggressive variant of malignant melanoma.

  • characterized by the absence of a radial growth phase
  • seen on the trunk and limbs of patients in their fifth or sixth decade of life
  • males are commonly affected than females (1)
  • typically, it arises on apparently normal skin, has relatively little melanin and a rich blood supply
  • patients have a symmetrical, raised, firm, often uniformly coloured and frequently non-pigmented nodule which continue to enlarge and become more raised (2)
  • ulceration is common, giving a poorer prognosis.
