Clear cell carcinoma of the salivary glands is a rare tumour that represents less than one per cent of all salivary tumours. They are divided into a biphasic, epithelial-myoepithelial carcinoma and a monophasic pattern which may be myoepithelial or ductal in origin. The latter is accompanied by prominent fibrohyaline stroma and has been described recently as hyalinizing clear cell carcinoma (HCCC). Most of the HCCC occur in the oral cavity, and are associated with minor salivary glands, unlike the biphasic pattern which is more common in the major salivary glands. In the oral cavity, the commonest site is the palate followed by the lips and the buccal mucosa. Its occurrence in the oropharynx and the larynx is extremely rare.
涎腺透明细胞癌是一种罕见肿瘤，占所有涎腺肿瘤的比例不到1%。它们分为双相性上皮-肌上皮癌和单相性模式，单相性模式可能起源于肌上皮或导管。后者伴有显著的纤维玻璃样间质，最近被描述为透明变性透明细胞癌（HCCC）。与双相性模式多见于大涎腺不同，大多数HCCC发生在口腔，与小涎腺有关。在口腔中，最常见的部位是腭部，其次是嘴唇和颊黏膜。其发生于口咽和喉部极为罕见。
