Background: Pleomorphic adenoma (PA) of the major salivary glands has been documented to occur in various sizes ranging from 1 cm to 10 cm in their widest diameter; however, they can assume a grotesque proportion as a consequence of uninhibited growth in cases with delayed presentation. Patients and Methods: A retrospective study of all patients with PA of the major salivary glands with sizes >10 cm in its widest dimension and seen over a 10-year period was undertaken by retrieving sociodemographic and clinical data from patients' case files from the Oral and Maxillofacial Unit of a Nigerian Teaching Hospital. Results: Case files of ten patients (4 males and 6 females) were reviewed over the study period. The ages ranged from 14 to 61 years, mean 33.8 ± 17.97 years. Equal distribution of five cases of PA was noted in the parotid and submandibular glands, respectively. The onset of symptoms ranged from 3 to 20 years and the largest tumor was 27 cm in its largest diameter. Only one case of malignant PA was recorded. Conclusion: Prevalence of giant PA from the study was found to be 13.5%, with a greater occurrence in the female (60%) patients compared to the male (40%) patients and with an equal distribution in both parotid and submandibular glands. PA of major salivary glands can assume a grotesque proportion when timely surgical intervention is not sought. Complete surgical excision in benign lesions can guarantee a cure and restore self-esteem.
