INTRAORAL SALIVARY-GLAND TUMORS IN THE WEST MIDLANDS

Intra-oral salivary gland tumours reported from the West Midlands over the years 1975-88 were examined as to a number of epidemiological variables; the question as to their increasing incidence was also addressed. The findings were largely in agreement with those of most previous authors in that most of the tumours occurred in the palate, but whereas most of these were benign, a large proportion of those in other sites were malignant. However, firm conclusions are difficult to draw since there is much disagreement over reporting criteria. An international workshop and comprehensive tumour registries are required in order to determine more accurate data and conclusions. Similar cooperation is necessary in order to substantiate or refute the suggestion that the incidence of salivary gland tumours is increasing.
