Facial pain as a symptom of nonmetastatic lung cancer.
Patients with nonmetastatic lung cancer may rarely experience facial pain as a presenting symptom, during the course of the disease or upon recurrence of the disease. This study reviews a 10-year experience at Mayo Clinic. The aim of this study was to (1) further characterize the clinical features of facial pain as a symptom of nonmetastatic lung cancer, and (2) assist clinicians in recognizing this association. Ten cases were identified. All patients complained of severe, aching, facial pain typically aural-temporal in location, ipsilateral to the lung cancer. Six of the 10 cases involved the left side. Recent weight loss was present in 7 of 10 patients, with an elevated sedimentation rate in 6. Digital clubbing was documented in three. Neurologic examinations and neuroimaging were normal in all patients. Lumbar puncture, when performed, was normal. Facial pain preceded the diagnosis of lung cancer by 1 to 24 months. In three patients, facial pain was the initial symptom of tumor recurrence. Four of the 10 tumors were adenocarcinoma; radiation with or without chemotherapy appears to be the treatment of choice for the facial pain. The presumed mechanism is local invasion of the vagus nerve. In suspected cases, a chest x-ray and chest CT are indicated.
