The patient was a 55-year-old man who visited hospital for pain in both knees and lower legs. Physical examination revealed clubbed fingers, and radiographs of the extremities and bone scintigraphy showed findings of periosteogenesis in the long tubular bones. After thorough examinations, he was diagnosed with stageⅣB lung adenocarcinoma complicated by pulmonary hypertrophic osteoarthropathy. He received combined treatment with carboplatin + pemetrexed + durvalumab + tremelimumab as first line therapy. After treatment, the tumor shrank well and the arthritis and other symptoms improved. To the best of our knowledge, there have been no reports about the treatment of lung cancer complicated by pulmonary hypertrophic osteoarthropathy with anti-PD-L1 and anti-CTLA-4 antibodies, and so we report this apparently rare case.
