Abstract
An unusual case of odontogenic carcinoma of the mandible showing a sarcomatous proliferation is described. The tumour had caused invasive bone destruction with extension into the soft tissues of the cheek. It was successfully treated by resection of the mandible and radical neck dissection. Although ameloblastomatous features were observed in an infrabony area, the majority of the intrabony lesion consisted of a proliferation of epithelial cells arranged in fine strands or networks which were randomly scattered in a collagenous stroma in the periphery. The tumour cells assumed a fibroblastic appearance and were intermingled with stroma cells in the extrabony lesion. The lesion could not be placed in any of the three entities of odontogenic carcinoma in the WHO classification.
