Papillary cystadenoma is a relatively rare salivary gland tumor which has been reported sometimes in association with minor salivary glands.
Here, we report a case of papillary cystadenoma of minor salivary gland origin located in the floor of the mouth, in a 59-year-old woman. The patient complained of swelling of the floor of the mouth. During the course of the first medical examination, a circumscribed, elastic hard, movable, dark reddish oval mass was found in the floor of the mouth just by the lower right wisdom tooth, measuring 12×13mm.
Clinically an hemangioma was suspected. Under general anesthesia, the lesion was totally excised. Histologically, sections revealed a small and a large cystlike cavities lined with tall, eosinophilic granular epithelial cells disposed in papillary projections filling the lumen. Histopathologically it was diagnosed as a papillary cystadenoma.
There was no evidence of recurrence in the patient 7 months after the operation.
