[Buccal metastases from soft-tissue cancers. A report on 3 cases (author's transl)].

Histological examination of the gingivovestibular lesion in the first case with known kidney cancer, confirmed the metastatic nature of the buccal tumor and its origin. The second case raised the problem of the diagnosis of a labial swelling occurring during widespread metastases from breast cancer. The third case was more complex as the palatine lesion was seen initially, and metastatic seeding extremely rapid. This led to the hypothesis only, that bronchial cancer was the primary lesion.
