Unicystic Mucoepidermoid Carcinoma: A Pitfall for Clinical and Pathologic Diagnosis

Figure 3

The CT images and histology images of one recurred patient of type B UC-MEC. (a) Contrast-enhanced CT scan of the primary lesion showed that it was cystic and well outlined on the hard palate. (b) 2 years later, CT scan of the recurred lesion showed a well-circumscribed lesion. (c) The proliferative clusters of epithelial cells were observed in the subepithelial area of the fibro-collagenous wall in the primary lesion (HE 10x). (d) The epithelial clusters were invasive into jaw bone in the recurrent lesion (HE 10x).
