What is hyalinizing clear cell carcinoma? Hyalinizing clear cell carcinoma (HCCC) is a slow-growing type of head and neck cancer. A genetic alteration involving the EWSR1 gene is found in most HCCCs. Where is hyalinizing clear cell carcinoma normally found? Most HCCCs tumours arise from minor salivary glands which are normally found in the lip, …

Other possible locations include the skin, lungs, breasts, and prostate gland. Adenoid cystic carcinoma grows slowly but spreads widely into surrounding tissues. However, unlike …
