title: Hyalinizing clear cell carcinoma of the base of tongue.
abstract: Hyalinizing clear cell carcinoma is a rare, low-grade neoplasm of the minor salivary glands. It is composed exclusively of epithelial cells with optically clear cytoplasm. There are only a few isolated cases reported in the literature involving the base of tongue. The treatment of choice is wide excision and selective neck dissection, with or without radiotherapy. The prognosis of these tumours is good. A 57-year-old male patient presented with a lesion in the base of tongue, which was well enhanced on contrast computerized tomography scan. Once confirmed by biopsy, the hyalinizing clear cell carcinoma was resected via a transcervical approach. The patient underwent postoperative radiotherapy. There was no evidence of locoregional recurrence or distant metastasis at 18 months of follow up.
