title: Pre-auricular oat cell carcinoma metastases.
abstract: The oat cell tumor is a particularly lethal form of bronchogenic carcinoma. Cutaneous metastases occur occasionally in the pre-auricular area. In addition to benign and malignant parotid lesions, the differential diagnosis of a pre-auricular mass must now include metastatic disease, particularly if a history of a thoracic malignancy is elicited. We present two such cases of metastatic oat cell carcinoma in the pre-auricular region.
