  • Title: [Report of a spindle cell myoepithelialioma of the minor salivary glands with extensive lipomatous component].
    Author: Kern MA, Kasper HU, Drebber U, Guntinas-Lichius O, Veelken F, Ortmann M.
    Journal: Laryngorhinootologie; 2005 Jun; 84(6):432-5. PubMed ID: 15940575.
    Abstract:
    Myoepitheliomas of the salivary glands are rare benign tumors composed of spindle-shaped myoepithelial cells, but may show plasmacytoid, epitheloid and clear cell-types that principally exhibit myoepithelial but not ductal differentiation. These tumors are mainly located in the major salivary glands and have sometimes abundant, acellular, mucoid or hyaline stroma but lack chondroid and myxochondroid foci, probably representing the one end of the spectrum of pleomorphic adenoma. Lipomatosis in the form of isolated small islands or scattered single lipocytes, is quite uncommon, and a large amount of adipose tissue in a pleomorphic adenoma and myoepithelioma is a rarity and only described in major salivary glands. We present the case report of a 38-year old man with a myoepithelioma of the minor palatinal salivary glands with extensive lipomatosis as an example of this rare phenomena.
