|Description:||This is advanced malignant melanoma. At the left, one can see a plaque of early, radial growth phase superficial spreading melanoma. To the right, and contiguous with the plaque, is a pink (amelanotic) nodule of deeply invasive vertical growth phase melanoma. Melanomas diagnosed at this stage have a poor prognosis; many of these patients develop metastatic disease and die from their cancer. In the majority of instances, the plaque stage of melanoma is present for a sufficient period of time to permit its diagnosis and removal before it progresses to a more advanced (and more difficult to treat) stage.
