Since epithelial inclusions in axillary lymph nodes are rare, some diagnostic problems concerning their nature have arisen. We report a case of a cystic squamous epithelial inclusion in an axillary lymph node of a patient affected by a high grade breast carcinoma with focal squamous differentiation. Although the lesion was histologically benign, the possibility that it represents a well-differentiated squamous metastasis cannot be completely ruled out. To our knowledge, this is the first case of an epithelial lymph node inclusion associated with a breast carcinoma showing morphological evidence of squamous differentiation. Here, we discuss the diagnostic problems and give a review of the literature.
由于腋窝淋巴结中的上皮包涵体罕见，因此出现了一些关于其性质的诊断问题。我们报告了一例患有高级别乳腺癌并伴有局灶性鳞状分化的患者腋窝淋巴结中的囊性鳞状上皮包涵体病例。尽管该病变在组织学上为良性，但不能完全排除其为高分化鳞状转移瘤的可能性。据我们所知，这是首例与显示鳞状分化形态学证据的乳腺癌相关的上皮性淋巴结包涵体病例。在此，我们讨论诊断问题并对文献进行综述。
