The authors describe a rare case in which a cervical metastatic basal cell carcinoma (BCC) occurred from a small, non-ulcerated primary lesion on the trunk of a female patient. The metastasis had the same immunohistochemical staining pattern as several biopsies from the primary site. It was immediately adjacent to the left neck regional nodes and we view this as an in-transit metastasis. There is often debate about the validity of BCC metastases to lymph nodes but an in-transit lesion strengthens the argument that this does rarely occur.
作者描述了一例罕见病例，一名女性患者躯干上出现一个小的、未溃疡的原发性病变，进而发生了颈部转移性基底细胞癌（BCC）。转移灶与原发部位的多次活检具有相同的免疫组化染色模式。它紧邻左颈部区域淋巴结，我们认为这是一种途中转移。关于基底细胞癌转移至淋巴结的有效性常常存在争议，但途中病变强化了这种情况确实很少发生的观点。
