title: Malignant pleural mesothelioma initially diagnosed on cervical lymph node biopsy.
abstract: Reported herein is a case of malignant pleural mesothelioma, initially diagnosed on cervical lymph node biopsy. A 58-year-old man, without obvious evidence of asbestos exposure, exhibited repeated pleural effusion (cause unclear), which was resolved by diuretics. A neck mass was apparent and was identified pathologically as a lymph node metastasis of malignant mesothelioma. F-18 fluorodeoxyglucose positron emission tomography/CT established the diagnosis of malignant pleural mesothelioma. Two conclusions emerge from this report: (i) cervical lymph node metastasis of pleural mesothelioma, although rare, should be included in differential diagnosis; and (ii) positron emission tomography/CT is useful for establishing a diagnosis of mesothelioma.
