Mucoepidermoid carcinoma (MEC) is the malignant salivary gland neoplasm chiefly occurred in minor salivary gland. One of the rare variant of MEC is intra-osseous variant found in the jaws known as central mucoepidermoid carcinoma. Presently in this case report, we described a 28-year-old male diagnosed with central low grade mucoepidermoid carcinoma subsequently with the presence of asymptomatic swelling with a history of trauma. Clinically mimicking a cystic lesion and radiographically gives an idea of mixed radio-opaque radiolucent lesion which creates a confusion to render a final diagnosis. The site, duration and history of the case are uncommon for the occurrence of intra-osseous malignant lesion of salivary glands. Present case adds new dimensions to the present knowledge about the clinical and radiographical picture that a central mucoepidermoid carcinoma can mimic.
黏液表皮样癌（MEC）是主要发生于小涎腺的恶性涎腺肿瘤。MEC的罕见变异型之一是发生于颌骨的骨内型变异，称为中央型黏液表皮样癌。在本病例报告中，我们描述了一名28岁男性，被诊断为中央型低级别黏液表皮样癌，随后出现无症状肿胀且有外伤史。临床上类似囊性病变，影像学上表现为混合性不透光及透光病变，这给最终诊断造成了困扰。该病例的部位、病程和病史在涎腺骨内恶性病变的发生中并不常见。本病例为目前关于中央型黏液表皮样癌可模仿的临床和影像学表现的知识增添了新内容。
