MASILELA, MMJ. A 16 year retrospective analysis of intraoral minor salivary gland pleomorphic adenoma in an African population. S. Afr. dent. j. [online]. 2015, vol.70, n.1, pp.22-24. ISSN 0375-1562.

OBJECTIVES: The aim of the study was to determine the relative frequency and demographic characteristics of intraoral minor salivary gland pleomorphic adenomata (IMPA) affecting a group of patients who attended the Medunsa Oral Health Centre of the University of Limpopo, South Africa. MATERIALS AND METHODS: The records of all the IMPA diagnosed in this rural and periurban Southern African population sample between 1995 and 2011 inclusive were retrieved from the archives of the Department of Oral Pathology. The cases were reviewed and analysed for age, gender and site of occurrence. The findings were compared with other studies reported in the literature. RESULTS: One hundred and fifty two cases of pleomorphic adenomata (PA) were diagnosed between 1995 and 2011 of which 115 cases were encountered in intraoral minor salivary glands. The age of the patients ranged from 7 to 91 years with a mean of 38.5 years. The peak of incidence was in the third decade; however the tumour was relatively common in the sample through the second to the sixth decades of life. There was a female predilection (67.5%) demonstrated with the ratio of male to female of 1:2.3. Most males were diagnosed in their third decade of life whereas affected females were predominantly in their fifth decade. The most common site of occurrence was palate (78.6%) followed by buccal mucosa (12.0%) and upper lip (2.6%) and the distribution was the same for both females and males. CONCLUSION: IMPA diagnosed in this South African population shows demographic characteristics similar to those reported in most published studies in the world. In comparison with other studies, however, females were significantly more frequently affected than the males.
