A case of multiple familial trichoepithelioma was studied by electron microscopy. Tumour cells showed a dilated, rough endoplasmic reticulum (rER), in which banded, electron-dense structures measuring approximately 50 nm in width were found. Some of these banded structures were arranged parallel to each other with an interval of 250 nm.
通过电子显微镜对一例多发性家族性毛发上皮瘤进行了研究。肿瘤细胞显示粗面内质网（rER）扩张，其中发现了宽度约为50nm的带状、电子致密结构。这些带状结构中的一些彼此平行排列，间距为250nm。
