Abstract
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 expression of nestin, CD133, podoplanin, and insulin-like growth factor 1 receptor (IGF-1R).
RESULTS: OM failed to react with antibodies applied in this study, with the exception of IGF-1R in tumour cells.
DISCUSSION: OM is a poorly characterized benign, invasive tumour of the jaws. The absence of stem cell marker in OM does not exclude possible temporary expression of these antigens during certain phases of tumour development. The identification of IGF-1R in OM is shared with numerous tumours and indicates the ability of these tumour cells to respond to growth factors.
