While the incidence of early-stage melanoma has dramatically increased over the past decades, the incidence and mortality rates of thick melanomas have remained relatively stable during the same period. A number of alternative theories have been postulated in order to explain these divergent trends between thin and thick melanomas, among which is the question of whether nodular melanoma may originate in the dermis. This concept has gained support from recent improvements in the understanding of the origin of melanocytes and the morphological and molecular diversity of melanoma. A dermal origin would plausibly explain why efforts at improving the early detection of melanoma largely fail, as it implies an initially intradermal growth that is hidden from our eyes until clinical signs and symptoms become only secondarily apparent. In light of this, at the current stage, the vision that no one should die of melanoma is an impossible mission.
在过去几十年中,早期黑色素瘤的发病率急剧上升,而同期厚黑色素瘤的发病率和死亡率却相对稳定。为了解释薄型和厚型黑色素瘤之间这些不同的趋势,人们提出了一些替代理论,其中包括结节性黑色素瘤是否可能起源于真皮的问题。这一概念得到了近期对黑素细胞起源以及黑色素瘤形态和分子多样性认识进展的支持。真皮起源似乎可以解释为什么改善黑色素瘤早期检测的努力大多失败,因为这意味着最初是皮内生长,在临床体征和症状继发出现之前一直隐藏在我们视线之外。鉴于此,在现阶段,“不应有人死于黑色素瘤”这一愿景是一项不可能完成的任务。
