RESUMO
2 additional examples of sialoadenoma papilliferum, one occurring in the palate of a 32-year-old woman and the other in the palate of a 43-year-old man, have been added to the previously reported 11 cases. 9 of the 13 reported cases occurred in the palate with a 5.5:1 prevalence in men. The age at discovery ranged from 32 to 77 years. Whether these lesions represent a benign salivary gland tumor or hyperplasia of duct epithelium remains debatable. Surgical excision apparently effects a cure as no recurrences have been reported.

A 20-year-old man presented with a painless enlargement of the maxillary gingiva with no bone involvement. Microscopic examination with special stains confirmed the diagnosis of a clear cell variant of a calcifying epithelial odontogenic tumor (Pindborg tumor). This is the second reported case of such a variant in an extraosseous location.

Primary malignant tumors of vascular origin are exceedingly rare in the oral cavity. Consequently, knowledge of their clinical and pathologic features is scanty. The varied array of terms applied to malignant vascular tumors has only further confused the issue. This article presents a review of twenty examples of oral malignant vascular tumors, with a report of a single personally studied case. Specifically, this case presented as a soft-tissue gingival lesion which subsequently invaded bone and represents a malignant hemangioendothelioma.
