We present a retrospective study of 196 patients with intraoral minor salivary gland tumours, 128 malignant and 68 benign, diagnosed from 1954 to 1993 in the A.C. Camargo Hospital, São Paulo, Brazil. Sixty‐five percent of the cases occurred in the palate, followed by tongue (9.7%) and retromolar area (6.1%). Pleomorphic adenoma was the most common benign tumour, and mucoepidermoid carcinoma was predominant among the malignant tumours. Surgery was the main treatment method and postoperative radiotherapy and radiotherapy alone were used in 40 and 15 patients, respectively. Local recurrence was observed in two patients with pleomorphic adenoma and in eight patients with malignant tumours. Regional lymph node metastases occurred in four cases and distant metastases in five. Forty‐six of 47 patients with benigh tumours who were followed up from 1 to 7 years were alive without disease. Twenty‐four of 79 patients with malignant tumours who were followed up for at least 5 years died due to the tumour and 47 were alive without disease.
