Composite Epstein-Barr Virus-associated T-lymphoblastic and Peripheral T-cell Lymphomas: A Clonal Study.
A 30-year-old woman was diagnosed with T-lymphoblastic lymphoma (T-LBL) that harbored a clonal Epstein-Barr virus (EBV) genome. At relapse, axillary lymph node adenopathy, which was diagnosed as peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS), was detected. ⋯ Interestingly, the PTCL-NOS cells lacked CD21 expression. Our case suggests that EBV might infect immature CD21-positive T-cells, and CD21-negative PTCL-NOS might subsequently arise through phenotypic changes.

Observational Study
Multidisciplinary Team Care Delays the Initiation of Renal Replacement Therapy in Diabetes: A Five-year Prospective, Single-center Study.
Objective Although recent reports have highlighted the benefits of multidisciplinary team care (MTC) for chronic kidney disease (CKD) in slowing the progress of renal insufficiency, its long-term effects have not been evaluated for patients with diabetes mellitus (DM). We compared the renal survival rate between MTC and conservative care (CC). Methods In this five-year, single-center, prospective, observational study, we examined 24 patients (mean age 65.5±12.1 years old, men/women 18/6) with DM-induced CKD stage ≥3 in an MTC clinic. ⋯ On a multivariate analysis, MTC (hazard ratio [HR], 0.434, 95% CI 0.200-0.939) and the slope of the estimated glomerular filtration rate during the first year (HR, 0.429 per 1 mL/min/m2/year, 95% CI 0.279-0.661) were negatively associated with renal events. Conclusion MTC for DM-induced CKD is an effective strategy for delaying RRT. Long-term MTC can demonstrate reno-protective effects.

Abdominal ultrasonography in a 70-year-old woman showed a hypoechoic mass, 14 mm in diameter, in the pancreatic body. Computed tomography showed a mass with contrast effect in the pancreatic body. Test results for endocrine factors or tumor markers were normal. ⋯ Over 8 years of monitoring, the tumor diameter increased to 18 mm, until pancreatic tumor enucleation was performed. The postoperative diagnosis was pancreatic hamartoma, a rare type of benign pancreatic tumor. The preoperative diagnosis of pancreatic hamartoma is difficult, but consideration must be given to the possibility of hamartoma when encountering pancreatic tumors.

A 76-year-old woman with branch duct intraductal papillary mucinous neoplasm (IPMN) was admitted with epigastric pain and vomiting. She had received warfarin due to a history of deep vein thrombosis. A blood test showed decreased serum hemoglobin and elevated serum amylase. ⋯ We suspected rupture of a pseudoaneurysm and performed trans-catheter angiography. Angiography showed extravasation from the posterior superior pancreaticoduodenal artery, and coil embolization was performed. It is important to be alert for the formation of pseudoaneurysm in patients with cystic neoplasms.
