A trabecular (Merkel cell) carcinoma arising in the wall of an epidermal cyst in a 58-year-old white male metastasized, 17 months after local excision, to an inguinal lymph node. Ultrastructural studies showed polygonal tumor cells with typical dense-core granules. Although squamous-cell carcinoma and other malignant neoplasms have been reported rarely to have arisen in epidermal cysts, a literature search failed to find a precedent for the present case.
一名58岁白人男性的表皮囊肿壁上发生的小梁（默克尔细胞）癌，在局部切除17个月后转移至腹股沟淋巴结。超微结构研究显示多边形肿瘤细胞具有典型的致密核心颗粒。尽管鳞状细胞癌和其他恶性肿瘤很少有报道发生于表皮囊肿，但文献检索未发现本病例的先例。
