I had removed a papilloma from this manscheek eight years previously.

Much has been written with regard to the sites of origin ofepitheliomas and rodent ulcers. In skin practice both are mostfrequently seen on the face—the rodent very rarely elsewhere, but theepithelioma not infrequently on the extremities and on the genitalorgans. The primary lesions in the latter situations present the samepicture as the facial (Fig. 8). I show you now two slides. The first shows the sites of origin of ahundred primary epitheliomas on the face (Fig. 12), and the secondthe sites of origin of a thousand rodent ulcers on the face (Fig. 13).You will see at a glance that the lower lip and upper lid arefrequently invaded by epithelioma and rarely by rodent, that the KARLV KPITHKLIOMA OF THK SKIN. 379 bridge
