Abstract
We report a case of aggressive epithelial odontogenic ghost cell tumor arising from the mandible in a 32-year-old man. On CT and MR studies, the tumor was seen as a large, heterogeneous soft-tissue mass that caused marked destruction of the mandible and invaded the mouth floor and tongue base. The tumor displayed a variety of densities and signal intensities on CT and MR images, which correlated well with the degree of cellularity of epithelial islands, abundance of ghost cells and eosinophilic materials, calcification, and cystic areas on histologic sections. Owing to the unpredictable biological behavior of this type of tumor, careful, long-term follow-up is highly recommended.
摘要
我们报告一例发生于一名32岁男性下颌骨的侵袭性上皮性牙源性幽灵细胞瘤。在CT和MR检查中，肿瘤表现为一个巨大的、不均匀的软组织肿块，导致下颌骨明显破坏，并侵犯口底和舌根。肿瘤在CT和MR图像上显示出多种密度和信号强度，这与组织学切片上上皮岛的细胞密度、幽灵细胞和嗜酸性物质的丰富程度、钙化以及囊性区域密切相关。由于这类肿瘤的生物学行为不可预测，强烈建议进行仔细的长期随访。
