title: [Multiple malignant tumors].
abstract: The cases of six tumour patients are presented. One patient had four, the others three or two primary cancers in 12 years. The importance of keeping operated patients under supervision is pointed out and it is stressed that on the appearance of a new tumour the physician must not suppose incurability. In the case of gastrointestinal malignomas attention should be paid to cancer to the skin.
