We report the case of a patient in whom lichen nitidus with hemorrhage was found on the palm and the thigh. Histopathologically, the small vessels in the lesions showed extensive changes and were increased in number. The capillary walls revealed degenerative changes with extravasation of erythrocytes. On electron microscopy, amorphous, electron-dense deposits were observed along the outside of the endothelial cells. These findings can explain the presence of the hemorrhagic changes. We describe this as a case of purpuric lichen nitidus.
