Metastatic lung carcinoma involving the periodontium. Report of a case.

A CASE OF METASTATIC BRONCHOGENIC carcinoma to the gingiva in a 47-year-old male is reported. The gingival lesion developed as a quickly growing mass and appeared 2 months after surgical excision and radiotherapy of the lung carcinoma were completed. The gingival tumor was histopathologically diagnosed as a poorly differentiated squamous carcinoma. Comparative cytologic studies showed similarities between the gingival metastasis and the previous lung cancer.
