Background: Clear cell carcinoma (CCC) is a low-grade malignant tumor that usually appears in the minor salivary glands of the oropharynx and other sites and is a rare feature of salivary gland tumors. Methods: We present here the case of a 58-year-old woman with no medical history. She consulted for swelling under the left mandible. On clinical examination, the patient had a swelling of the left tonsil. A biopsy was performed and histological and immunohistochemical results were used to diagnose a Hyalinizing clear cell carcinoma of the left tonsil. Cervical facial CT scan showed a tumor process of the left tonsil compartment with bilateral cervical lymphadenopathies. No other lesions were detected in the systemic evaluation. Surgery was not feasible in this patient and therefore the decision to opt for concurrent chemo-radiotherapy was made. Results: The patient was reviewed after 1 month. Clinically, it shows a regression of cervical adenopathies and a decrease in the volume of the tonsillar tumor mass. Skin reactions almost resolved. The patient was doing well. Conclusion: concurrent chemo-radiotherapy is used in the treatment of locally advanced clear-cell carcinoma of the tonsils that escape surgery with good disease control results.
