BackgroundGhost cell odontogenic carcinoma (GCOC) is a very rare malignant neoplasm. Tumor volume may be a more precise alternative for determining size, usually measured by maximum linear dimension. The purpose of this case report is to highlight the importance of obtaining three-dimensional images of the tumor for volumetric analysis in order to improve the chances of surgical success. This report presents a case of GCOC infiltrating the maxillary sinus through the palate. The lesion was surgically treated and subsequently selected for volumetric reconstruction and analysis of the tumor by using the InVesalius software. In this case report, we describe the use of a pictorial technique in which the tumor volume was calculated to help predict the surgical results.ResultsThe tumor could be visualized in 3D, with color improving the image of the segmented volume and thus increasing the perception of boundaries and depth.ConclusionRecognition of the lesion shape by volumetric analysis can provide the surgical team with clearer information, helping in surgical planning and consequently increasing the chances of surgical success.
