Adenoma, Pleomorphic
Research News and Information
Definition of 'Adenoma, Pleomorphic'A benign, slow-growing tumor, most commonly of the salivary gland, occurring as a small, painless, firm nodule, usually of the parotid gland, but also found in any major or accessory salivary gland anywhere in the oral cavity. It is most often seen in women in the fifth decade. Histologically, the tumor presents a variety of cells: cuboidal, columnar, and squamous cells, showing all forms of epithelial growth.

Update on selected salivary gland neoplasms.
30 Oct 2009 
CONTEXT: Malignancies of the salivary gland are uncommon and account for 0.3% of all malignancies. In addition to their rarity, diagnosing these tumors can be challenging given the histologic overlap among various subtypes, their morphologic ... Read more...
30 Aug 2009 Our aim was to assess the specific ultrasonic characteristics of pleomorphic adenoma and Warthin's tumor in major salivary glands. METHODS: We retrospectively reviewed and analyzed the ultrasonographic (US) features of 19 pleomorphic adenomas in 16 ... Read more...
30 Aug 2009 AIMS: The balance between matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) is involved in the morphogenesis of normal salivary gland as well as in the mechanisms of tumour invasion and metastasis. The role of MMPs and TIMPs in ... Read more...
