Context: Mesenchymal odontogenic tumors arise from the remnants of the mesenchymal portion of tooth germ. Central odontogenic fibroma (COF), odontogenic myxoma (OM) and Ameloblastic fibroma (AF) are closely related and show varied clinical presentation and overlapping histopathology. They are differentiated by their collagen quantity, maturity and distribution. Diagnostic difficulties are posed...

UNLABELLED Odontogenic myxoma (OM) is a rare mesenchymal tumour arising in the jaws. The origin and pathogenesis of OM is poorly understood. The aim of this study was to characterize OM by immunolocalization of certain antigens in the tumour that are relevant for cellular differentiation, migration and maintenance. MATERIALS AND METHODS Five OMs were immunohistochemically investigated for exp...
