title: [Multiple cancers of the oral cavity. An unusual association of an epidermoid carcinoma of the mucosa with a bone carcinoma of salivary origin].
abstract: Multiple cancers cannot be considered as accidentally discovered curiosities. They have their own characteristics and differ from multifocal cancers or those secondary to a primary cancer. The authors describe the rare case of a patient suffering from two different types of cancer of the oral cavity; the first one was an epidermoid carcinoma of the upper alveolar mucosa, the second a salivary carcinoma of both epidermoid and glandular type situated within the bone of the mandible. A comparative study was carried out on the muco-epidermoid tumour and the adenosquamous carcinoma which proved the separate indentity of the second cancer. The galloping development of the adenosquamous carcinoma raises the problem of the effect of the primary cancer on the development of the second.
