[A case of lung adenocarcinoma with Marie-Bamberger syndrome that improved by chemotherapy].

A 68-year-old man was admitted with arthralgia in both knees. Chest CT showed a tumor 4cm in diameter with a cavity in the right lung. Clinical stage IV (T2N3M1) lung adenocarcinoma was diagnosed. The thickness of the fibular cortex was shown on the radiograph and distal symmetric accumulation of extremities was shown using bone scintigraphy. These results suggested that the knee-joint pain was caused by Marie-Bamberger syndrome. After chemotherapy with cisplatin plus gemcitabine, the tumor decreased, and the bone pain disappeared. This is a case that showed the correlation between tumor reduction and bone pain in Marie-Bamberger syndrome.
