OBJECTIVES: To review the natural history of occult head and neck malignancy presenting with facial pain and evaluate the risk factors, diagnostic workup, and management of facial pain in the setting of occult malignancy.STUDY DESIGN: Retrospective chart review.SETTING: Tertiary care center.SUBJECTS AND METHODS: All patients presenting from 1980 to 2010 with facial pain and a delayed diagnosis of a head and neck cancer were reviewed.RESULTS: Thirty-eight patients were included. Onset of pain was rapid or sudden in 94.7%, intermittent in 84.2%, and sharp in 86.8%. Facial nerve weakness was present in 15.8%. Five patients had a history of locoregional skin cancer, and 14% had a history of malignancy. Average delay to diagnosis was 18.4 months. On average, the suspicious lesion was identified on the second scan (mean, 2.1; range, 1-4 scans). Diagnosis was suggested by magnetic resonance imaging in 54.8% and computed tomography in 38.7% of patients. The most common pathology was squamous cell carcinoma (39.5%), and the predominant location was the parotid gland (28.9%). Surgical resection (66%) was the most common intervention. In patients who received treatment and had clinical follow-up available for review, 97.0% (32/33) reported symptomatic improvement.CONCLUSIONS: In our series, sudden-onset, intermittent, sharp facial pain without resolution or improvement was associated with occult malignancy and should be considered in the differential diagnosis for facial pain. Based on the high incidence of early negative imaging, consideration should be given to repeat imaging when there is concern for malignancy. Therapeutic interventions often result in improvement of facial pain.
