Oral metastatic tumours are rare, and the main site affected is the mandible, with only few reports in the soft tissues. We are reporting a case of non-small cell undifferentiated carcinoma of the lung in a 52-year-old man, which developed metastasis to the vertebra, adrenal and upper vestibular gingiva. Clinically, the oral lesion mimicked a pyogenic granuloma. The biopsy established the gingival metastasis from lung cancer and after two weeks the patient died. This article showed a rare case of metastatic lung carcinoma to the gingiva and emphasized the differential diagnosis between proliferative lesions and metastatic tumours. © 2005 Elsevier Ltd.
