Abstract
Salivary gland tumors represent about 3% of all head and neck tumors, with the vast majority occurring in the parotid gland. Squamous cell carcinomas rarely are primary in the salivary glands, representing less than 1% of all parotid malignancies. A 76-year-old man was referred to Otorhinolaryngology due to a right preauricular swelling that had progressively increased in size. Physical examination revealed a painful, firm lesion in the right parotid region, with right peripheral facial palsy. Remaining ENT examination was normal. The biopsy showed a squamous cell carcinoma. CT scan showed a heterogeneous nodule, with peripheral contrast enhancement, in the deep lobe of the right parotid gland. No cleavage plane with the right masseter. No bone or perineural invasion and no signs of ganglionic or organic involvement. No lesions in another areas. Primary parotid squamous cell carcinoma is a rare, aggressive, high-grade salivary gland neoplasm, with worse prognosis than conventional ENT squamous cell carcinoma.
