A Case of Diffuse Large B-cell Lymphoma with Liver Involvement in a 67-Year-Old Woman Given Methotrexate for Rheumatoid Arthritis / 대한내과학회지

Prolonged inflammation or immunosuppression may cause lymphoproliferative disorders (LPD). Rheumatoid arthritis (RA) itself causes LPD. The immunosuppressive drug methotrexate (MTX) is used widely to treat RA, and is also related to the development of lymphoma. Although the detailed pathogenesis and association are still controversial, care is needed when managing patients with RA treated with MTX. Many reports indicate that discontinuing MTX can induce the regression of LPD. Here, we describe a case of diffuse large B-cell lymphoma that presented with liver involvement in a 67-year-old woman who had used MTX for RA for 15 years.

A Case of Systemic Capillary Leak Syndrome Presenting as Septic Shock / 대한내과학회지

Systemic capillary leak syndrome is a rare disease characterized by life-threatening attacks of reversible plasma extravasation and vascular collapse accompanied by hypotension, hemoconcentration, and hypoalbuminemia. A 36-year-old woman was admitted to this hospital with a fever, along with symptoms consistent with an upper respiratory tract infection and hypotension. Initial laboratory tests revealed several abnormal findings, including an elevated leukocyte count and hematocrit, hypoalbuminemia, and acute renal failure. Here, we report a case of successful treatment of systemic capillary leak syndrome, which can be difficult to distinguish from septic shock.
