Recurrent sialadenoma papilliferum of the buccal mucosa.

Sialadenoma papilliferum is a rare, benign, exophytic tumour of the salivary glands. The prognosis is exceptionally good. Since the lesion was first described, 30 cases have been reported in the English literature, and only one of these is known to have recurred. A case of sialadenoma papilliferum occurring in the buccal mucosa with recurrence three years after local excision, is presented. The literature is briefly discussed.
