Abstract

We hereby present a case of a 51-year-old woman with a pigmented nodule in the right axillary region. Histopathological examination revealed features consistent with an intradermal nevus. Notably, adjacent to the nevus, intralymphatic protrusion and lymphatic invasion were observed, comprising cells with morphological and immunohistochemical characteristics consistent with nevus cells. Next-generation sequencing revealed the BRAF V600E mutation. To date, 26 similar cases involving intralymphatic nevus cell protrusion and lymphatic invasion have been reported in the literature. Although this finding is rare and may pose a diagnostic challenge for pathologists, it should not be interpreted as indicative of malignancy. Rather, it must be assessed in the context of the lesion's overall histological architecture.

伴有淋巴内痣细胞突出和淋巴浸润的痣。
我们在此提出一个51岁的女性病例,右侧腋窝区域有色素结节。组织病理学检查显示与皮内痣相符的特征。值得注意的是,在痣附近,观察到淋巴内突出和淋巴浸润,包括形态学和免疫组织化学特征与痣细胞一致的细胞。下一代测序显示BRAF V600E突变。迄今为止,文献报道了26例涉及淋巴内痣细胞突出和淋巴浸润的类似病例。虽然这一发现是罕见的,可能会对病理学家提出诊断挑战,它不应该被解释为恶性肿瘤的指示。相反,它必须在病变的整体组织学结构的背景下进行评估。
