A case of sialadenoma papilliferum of the oral floor

We report a case of sialadenoma papilliferum of the oral floor. A 68-years-old woman visited our hospital in December 1993 complaining of a mass of the right side of the oral floor. A ball-like protrusion, measuring 6 × 6 × 5 mm, with sharp margins was found at the right side of the oral floor. The lesion was suspected to be a papilloma, and tumorectomy was performed under local anesthesia. Pathohistologic examination revealed a papillary sialadenoma, first reported by Abrams. The patient has done well since the operation. Tumors of the oral floor have not previously been reported in the literature.
