Abstract
Clear cell carcinoma, not otherwise specified（NOS）is rare and considered to be a low grade malignancy. This tumor is one of the new additions to the 2005 World Health Organization（WHO） classification of salivary gland tumors. We report a case of clear cell carcinoma, NOS of the upper lip. A 32-year-old female was admitted to our hospital with complaint of a mass in the upper lip. The mass was elastic hard and measured 13×10mm in diameter. The clinical diagnosis was a benign salivary gland tumor, and the tumor was surgically enucleated under general anesthesia. The histopathological diagnosis was clear cell carcinoma, NOS. At present, there has been no evidence of recurrence or metastasis. We report this case with some literature review.
