The patient was a 70-year-old female diagnosed with lung adenocarcinoma stage IV (cT1aN1M1b) in March 2012. Based on this diagnosis, she had received chemotherapy with cisplatin plus pemetrexed for two cycles. Although she was admitted to our hospital for third cycle of her chemotherapy in May 2012, treatment was held because of her abdominal pain. Physical examination showed mild right iliac fossa tenderness. Abdominal computed tomography showed a swelling of the appendix. We considered these findings to be consistent with acute appendicitis. An appendectomy was performed, and pathologic findings showed metastasis to the appendix from lung cancer. It was suggested that luminal obstruction of the appendix by the metastatic mass had caused acute appendicitis in this case.
