title: [Primary lung cancer with pulmonary hypertrophic osteoarthropathy mimicking bone metastasis; report of a case].
abstract: A 64-year-old man visited our hospital, due to right shoulder pain and fever. Chest X-ray revealed a well-defined tumor in the upper field of the left lung, and the histological diagnosis was adenocarcinoma. Bone scintigraphy demonstrated abnormal accumulation localized in the right shoulder joints. Although bone metastasis was highly suspected, pulmonary resection was performed to remove infected pulmonary tumor. A week after pulmonary resection, his shoulder pain dramatically improved, and abnormal accumulation in bone scan decreased definitely 1 month later. In conclusions, this is an atypical case of hypertrophic osteoarthropathy accompanying lung cancer.
