PURPOSE To evaluate the diagnostic value of gadolinium-enhanced dynamic magnetic resonance (MR) imaging of salivary gland tumors and correlate the MR imaging and histopathologic findings. MATERIALS AND METHODS Thirty-three salivary gland tumors in 29 patients were examined preoperatively at gadolinium-enhanced dynamic MR imaging. There were 22 benign and 11 malignant tumors. Dynamic contrast ...

Presumably benign neoplastic growths presenting structures characteristic of salivary gland tumors have been observed recently in sites quite unusual for such tumors. In one case the growth was attached to the right side of the bridge of the nose, in the other it arose in the left side of the hard palate. The presentation here is restricted to a brief account of the pertinent data on both of th...

Salivary gland cancers comprise a small subset of human malignancies, and are classified into multiple subtypes that exhibit diverse histology, molecular biology and clinical presentation. Local disease is potentially curable with surgery, which may be combined with adjuvant radiotherapy. However, metastatic or unresectable tumors rarely respond to chemotherapy and carry a poorer prognosis. Rec...

Cystadenoma and cystadenocarcinoma are rare salivary gland tumours histologically characterized by prominent cystic and frequently papillary growth. We present two cases of cystadenoma of a minor salivary gland (upper lip) and parotid cystadenocarcinoma respectively, captured between 834 salivary gland tumors studied in our hospital from 1980 to 2004. The authors review the clinical, histologic...

Saliva is a useful biofluid for the early detection of disease, but how distal tumors communicate with the oral cavity and create disease-specific salivary biomarkers remains unclear. Using an in vitro breast cancer model, we demonstrated that breast cancer-derived exosome-like microvesicles are capable of interacting with salivary gland cells, altering the composition of their secreted exosome...

Sialolipoma is a recently described histologic variant of lipoma and is characterized by well-demarcated proliferation of mature adipocytes with secondary entrapment of salivary gland elements. These tumors have been observed in both the major and minor salivary glands, with more than 20 cases being reported in the English literature. In general, the clinical presentation of sialolipomas of the...
