We present the ultrastructural features of a case of adenocarcinoma arising in ectopic hamartomatous thymoma in a 31 year old man, in the supraclavicular location. The tumor had a cribriform adenomatous component with a granular cell quality and mimicked a metastatic carcinoma. Ultrastructurally, the spindle cell component revealed clusters of tonofilaments and the tumor cells were attached by well developed desmosomes. The cytoplasm of adenocarcinoma cells contained peculiar cup-shaped bodies derived from the endoplasmic reticulum wrapped around the mitochondria.
我们报告了一例31岁男性锁骨上异位错构瘤性胸腺瘤中发生的腺癌的超微结构特征。肿瘤具有筛状腺瘤成分，具有颗粒细胞特征，类似转移性癌。超微结构上，梭形细胞成分显示有张力丝束，肿瘤细胞通过发育良好的桥粒相连。腺癌细胞的细胞质中含有源自内质网包裹线粒体的特殊杯状体。
