原发性表浅播散性黑色素瘤

定义

浅表性恶性黑色素瘤是黑色素瘤的最常见形式，约占所有黑色素瘤的70%。它的特点是表现为无症状的色素性皮肤斑块，形状不对称，在色调和色素程度上都有变化。在深入真皮并进入侵入性垂直生长阶段之前，它有一个相对较长的进行性表层扩展阶段（径向生长）。

The commonest form of melanoma, superficial spreading malignant melanoma accounts for about 70 per cent of all melanomas. It characteristically presents as an asymptomatic pigmented cutaneous macule which is asymmetrical in shape and displays variability in both hue and pigment intensity. It has a relatively long phase of progressive superficial extension (radial growth) before penetrating deeper into the dermis and entering an invasive vertical growth phase.
