A 42-year-old woman with a history of a surgically excised mucinous cystadenoma of the oral tongue, presented with a painful swelling in the oral tongue slowly growing for 1\u2009month. On clinical examination, there was a firm, relatively well-circumscribed mass in the left posterior border of the mobile tongue. Subsequent MRI scan revealed a heterogeneous lesion composed of multiple cysts separated by contrast enhancing septa, in the posterior two-thirds of the left tongue. Imaging findings were similar to those of the previously resected mass, suggesting local relapse of the primary lesion. A complete surgical excision was performed and the histopathological examination revealed typical features of a low-grade mucinous cystadenocarcinoma of minor salivary glands.<\/jats:p>","DOI":"10.1136\/bcr-2020-235932","type":"journal-article","created":{"date-parts":[[2020,10,30]],"date-time":"2020-10-30T17:10:51Z","timestamp":1604077851000},"page":"e235932","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Mucinous
