We report the case of a 77 year old woman with a giant proliferating trichilemmal cyst of the scalp and a central squamous-cell carcinoma. Six months after radical tumor-excision and dissection of the locoregionary lymph nodes the patient developed retroclavicular lymph node metastases. The tumor develops from cells of the hair matrix and tends to recur after excision; in rare cases malignant transformation may occur. We suggest radical excision and complete histological examination of the tumor. In cases of malignancy, lymph node-dissection is sometimes necessary. In these cases close postoperative follow-up of the patient is mandatory.
我们报告了一例77岁女性患者，其头皮患有巨大增生性外毛根鞘囊肿并伴有中央鳞状细胞癌。在进行肿瘤根治性切除及局部区域淋巴结清扫术后六个月，患者出现了锁骨后淋巴结转移。该肿瘤由毛基质细胞发展而来，切除后易于复发；在罕见情况下可能会发生恶性转化。我们建议对肿瘤进行根治性切除并进行完整的组织学检查。对于恶性肿瘤病例，有时需要进行淋巴结清扫。在这些情况下，对患者进行密切的术后随访是必不可少的。
