A 35-year-old woman was admitted for the examination of lower leg edema and proteinuria. A kidney biopsy showed membranous nephropathy (MN) with fine granular deposits of IgG along the glomerular capillary and poor spike formation, differing from primary MN in the presence of positive IgG3 and C1q. ⋯ The patient was diagnosed with syphilis, and the proteinuria disappeared with antibiotic treatment. In MN with positive IgG3 and C1q, syphilis nephropathy may be a differential diagnosis.

Case Reports
Multiple Retroperitoneal Abscesses Caused by Citrobacter koseri are Associated with a Poor Prognosis: A Case Report.
Citrobacter koseri causes opportunistic infections in various organs. We herein report an 84-year-old man with diabetes mellitus who presented to our hospital with left hip pain and walking difficulty. ⋯ Despite daily cleaning of the wound and antimicrobial therapy (with surgical drainage), the patient developed repeated pneumonia and small bowel hemorrhaging caused by disseminated intravascular coagulation and died on day 65 of hospitalization. Overall, retroperitoneal abscesses caused by C. koseri are rare, and multiple abscesses may show a poor prognosis.

Review Case Reports
Lethal Arrhythmia Induced by Severe Hypokalemia with Primary Aldosteronism: A Case Report and Literature Review.
A 26-year-old woman experienced sudden loss of consciousness with respiratory arrest while engaged in a heated conversation shortly after consuming a carbohydrate-rich meal; she was resuscitated immediately. Severe hypokalemia became evident and was deemed to have caused lethal arrhythmia. ⋯ Primary aldosteronism is frequently complicated by hypokalemia; however, hypokalemia-induced lethal arrhythmias are rare. Clinicians should recognize that primary aldosteronism can potentially cause sudden death in apparently healthy individuals; hence, an early diagnosis and proper treatment are critical.

An 86-year-old man successfully underwent percutaneous coronary intervention (PCI), in which a drug-coated stent (DCS) was placed in the left anterior descending coronary artery. However, stent thrombosis occurred twice after eight and two months. ⋯ At the six-month follow-up, clinical events were observed. Measuring the platelet aggregation ability can help clinicians understand the pathology of patients and determine treatment choices.
