Case of intraneural primary squamous cell carcinoma of the parotid gland without radiological correlate

Background Primary squamous cell carcinoma of the parotid gland is a rare but extremely aggressive malignant disease. Clinically, it usually presents as a painless mass. Cases of slowly progressive peripheral facial nerve palsy as the only sign of a malignant neoplasm of the parotid gland are rare and are often confused with Bell's palsy. However, progressive peripheral facial nerve palsies without signs of regeneration should be considered suspicious for malignancy until proven otherwise and require further diagnostic work-up.
