title: Banded structures in multiple familial trichoepithelioma.
abstract: 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.
