Polymorphous low-grade adenocarcinoma (PLGA) is a rare tumour that mostly affects oral minor salivary glands. Our review of the literature found that there are only two reported cases of PLGA originating in the nasopharynx. Another nasopharyngeal PLGA in a 14-year-old boy is reported, focusing on the histopathological features and ultrastructural findings.
