Hyalinizing clear cell carcinoma in the nasopharynx: A case report and literature review.

Background: Hyalinizing clear cell carcinoma (HCCC) arising from a minor salivary gland is a rare malignant neoplasm. Most HCCC has been reported in the palate and tongue base, and only rarely in the nasopharynx. Here, we report a rare case of nasopharyngeal HCCC.

Methods: A 44-year-old male who complained of otorrhea and aural fullness for 5 years was found to have a nasopharyngeal mass. Methods: HCCC by fluorescence in situ hybridization analysis. Methods: Surgical resection plus concurrent chemotherapy and radiation therapy were administered.

Results: The patient recovered well with symptoms improved at postoperative follow-up.

Conclusions: HCCC should be included in the differential diagnosis of nasopharyngeal mass. Overall, the prognosis of HCCC is positive after tumor resection and adequate management.
