An unusual case of hyalinizing clear cell carcinoma in a sinonasal cavity and cranial base

Hyalinizing clear cell carcinoma (HCCC) is a rare, predominantly minor salivary gland tumor. Most of these tumors occur in the oral cavity, mainly the palate and tongue. Primary localization of the tumor in the region of the nasal cavity and paranasal sinuses is extremely rare and, with only a few cases reported in the literature so far. We present an extremely rare case of a 61-year-old woman with hyalinizing clear cell carcinoma (HCCC), occupying the left posterior nasal and nasopharyngeal cavity, as a primary tumor location. The patient total recovery was uneventful, and she is now free of disease at three years postoperative follow-up.
