Non-bacterial thrombotic endocarditis (NBTE) is a condition that results in the development of vegetation on cardiac valves that are devoid of inflammation and bacteria. We herein report a 60-year-old man who transferred to our hospital because of a systemic embolism and heart failure. ⋯ During treatment, however, the patient was diagnosed with antiphospholipid syndrome and cancer. After 4 weeks of antibacterial therapy, the patient underwent open chest surgery, and the postoperative histological diagnosis was NBTE.

Case Reports
Non-tuberculosis Mycobacterial Pulmonary Disease Caused by Mycobacterium kiyosense, a New Species.
Non-tuberculosis mycobacterial (NTM) pulmonary disease (NTM-PD) is quite common, and newly identified species are being reported increasingly frequently thanks to advances in identification technologies. A 56-year-old woman had mild sputum production showed bronchiectasis with multiple small nodules, consistent with NTM-PD, on chest computed tomography. ⋯ We conducted whole-genome sequencing and identified the NTM isolates as Mycobacterium kiyosense, a species newly registered in 2023 from Japan. She was diagnosed with NTM-PD caused by M. kiyosense and received watchful waiting.

Congenital hemoglobin disorders typically present as hemolytic anemia, but there are also numerous reports of thrombotic complications in these diseases, suggesting an associated hypercoagulative state. In hemoglobin Köln, the most common type of unstable hemoglobinopathy worldwide, there have not been many reports of such thrombotic phenomena. ⋯ His father, who also had hemolytic anemia, presumably hemoglobin Köln, had a history of cerebral infarction. This case suggests that hemoglobin Köln, among other congenital hemoglobin disorders, may be a precipitating factor of thrombotic events.
