[Mucoepidermoid carcinoma of maxillofacial and oral cavity].

Authors experienced a case of low grade mucoepidermoid carcinoma in 48-year-old female and a case of low grade central mucoepidermoid carcinoma in 51-year-old female, respectively. The former occurred in right mandibular angle and showed multilocular radiolucent area surrounded by sclerotic rim but perforation of cortical bone connected with tumor mass in oral cavity radiographically. The latter occurred in left mandibular angle and ramus. Radiographic feature showed large radiolucent area in left mandibular angle and ramus, and destruction of coronoid process but intact condylar process. The origin of the latter might be mucus secreting cells of lined epithelium in dentigerous epithelium. In two cases metastases were not found.
