[Massive tumours of the parotid. A description of 12 cases (author's transl)].

A number of useful conclusions can be drawn from this research involving twelve personal cases. In the southern half of Madagascar, malignant tumours of the parotid are much more frequent than mixed tumours. This appears to be true whatever the age or sex of the patient or the clinical characteristics encountered. The absence of facial paralysis and adenopathy should never be considered to invalidate this theory. Mixed tumours exist but in about the same proportion as other tumours (cysts or vascular tumours) which are to be found here. When faced with any large latero-cervical tumour with no O.R.L. entrypoint or homo- or contro-lateral adenopathy, where there is no arteriography or extemporaneous biopsy available, the parotid should always spring to mind, and when surgery is carried out, the cervico-facial branch of the VIIth nerve at the lower pole or at the lower external face of the tumour should first be singled out.
