Merkel cell carcinoma (MCC) is a rare skin neuroendocrine tumor presumably arising from Merkel cells in the basal layer of epidermis. It is an aggressive tumor predominantly found on the head and neck area of elderly people, with a mortality rate around 41% for all stages. Complete spontaneous regression of MCC is seldom observed, mostly in elderly women. We describe complete spontaneous regression of large, histologically confirmed MCC in an elderly woman after biopsy, which occurred incidentally, while waiting for radical surgery with skin flap. Next-generation sequencing with SOPHiA Solid Tumor Plus Solution did not reveal any relevant gene mutations or rearrangements. An update of literature for these very rare cases is provided.
默克尔细胞癌（MCC）是一种罕见的皮肤神经内分泌肿瘤，可能起源于表皮基底层的默克尔细胞。它是一种侵袭性肿瘤，主要发生在老年人的头颈部，所有阶段的死亡率约为41%。MCC完全自发消退很少见，多见于老年女性。我们描述了一名老年女性在活检后组织学确诊的大型MCC完全自发消退的情况，这是在等待皮瓣根治性手术时偶然发生的。使用SOPHiA Solid Tumor Plus Solution进行的二代测序未发现任何相关基因突变或重排。本文提供了这些非常罕见病例的文献综述。
