As an uncommon, malignant salivary gland tumor with female predominance, hyalinizing clear cell carcinoma (HCCC) is regarded as an indolent tumor. The diagnosis of this rare tumor is challenging, and it depends on microscopic and immunohistochemical (IHC) studies. Although it is regarded as an indolent tumor, there are reports of unconventional forms with aggressive clinical courses. We report an atypical case of this rare tumor, HCCC, in a male patient who had a relatively large-sized mass (3.8×3.0 cm) on the right mouth floor with ipsilateral neck node metastasis. The clinical, radiological, pathological, and IHC features together with the clinical course are described.
