Merkel cell carcinoma (MCC) is an uncommon neuroendocrine cutaneous tumor with poor prognosis. It has the high rate of recurrence, mortality, regional nodal involvement, and distant metastases. It is difficult to diagnose MCC because of its non-specific clinical findings. It usually occurs on sun-exposed areas of the skin, mostly at head and neck. There is a difference in the incidence and prognosis according to site in the head and neck. However, there is no consented site-specific diagnosis, treatment or follow-up protocol for MCC at the head and neck. We herein report a case of MCC arising in the right earlobe of an otherwise healthy young man who has been diagnosed early, thereby successfully treated. With our closed follow-up, there was no tumor recurrence or complication at 33 months after diagnosis.
默克尔细胞癌(MCC)是一种罕见的神经内分泌性皮肤肿瘤,预后较差。其复发率、死亡率、区域淋巴结受累率及远处转移率均较高。由于其临床表现不具特异性,MCC难以诊断。它通常发生于皮肤暴露于阳光的部位,大多在头颈部。头颈部不同部位的发病率和预后存在差异。然而,目前尚无针对头颈部MCC统一的部位特异性诊断、治疗或随访方案。我们在此报告一例发生于一名健康年轻男性右耳垂的MCC病例,该病例得到了早期诊断并因此获得成功治疗。经过密切随访,诊断后33个月未出现肿瘤复发或并发症。
