Three cases of lung cancer with metastatic involvement of oral cavity

Abstract

Case 1 was a 45-year-old man who was admitted with mass in the right upper lobe. Percutaneous tumor biopsy revealed adenocarcinoma. Four months later, a metastatic tumor appeared on the right tonsil. After resection of the tonsil he was given irradiation. Although the metastatic tonsil tumor disappeared he died after 22 months. Case 2 was a 61-year-old man who had been admitted with left gingival tumor. Chest roentgenogram showed a mass in the left hilum. He was given a diagnosis of large cell carcinoma of lung with gingival metastasis. After 30-Gy irradiation the gingival tumor disappeared. Because the primary lesion progressed he died after 4 months. Case 3 was a 40-year-old man, admitted with a mass in the right upper lobe, in whom transbronchial biopsy revealed large cell carcinoma. One month later, a gingival tumor appeared and biopsy revealed it to be a metastatic tumor. After 60-Gy irradiation the gingival tumor disappeared. However liver and adrenal metastasis developed in the patient and he died after 4 months.
