Superficial spreading melanoma presents as a slowly growing or changing flat patch of discoloured skin. At first, it may resemble a melanocytic naevus (mole), ephelis (freckle), or lentigo. It becomes more distinctive in time, often growing over months to years or even decades before it is recognised.
