A 47-year-old woman with ulcerative colitis (UC) was admitted to our hospital for renal dysfunction and progressive anemia. Colonoscopy revealed intestinal lesions and pathological findings showed intravascular large B-cell lymphoma (IVLBCL). According to the polymerase chain reaction analysis of sequential rectal specimens, we concluded that she suffered from intestinal BCL, not UC. ⋯ The pathological findings of renal biopsy specimens indicated membranoproliferative glomerulonephritis (MPGN). Chemotherapy was continued and led to the remission of BCL and MPGN. We herein describe the first case of intestinal IVLBCL mimicking UC with secondary MPGN.

We herein report a novel mutation in a Japanese family with an X-linked Alport syndrome (AS) mutation in COL4A5. Patient 1 was a 2-year-old Japanese girl. ⋯ In summary, the identification of mutations and characteristic pathological findings was useful in making a diagnosis of AS. For a close long-term follow-up, the early detection and treatment of women with X-linked AS are important.

A 70-year-old woman with chronic hepatitis C was admitted to our hospital due to liver injury, cholecystitis, and disseminated intravascular coagulation with a fever and skin rash. She had been on a combination regimen of daclatasvir and asunaprevir for 2 weeks of a 24-week regimen. ⋯ Although daclatasvir and asunaprevir combination therapy is generally well-tolerated, some serious adverse effects have been reported. Our findings indicate that immunoallergic mechanisms were associated with daclatasvir and asunaprevir-induced liver injury.

Case Reports
Recurrent Cholangitis in a Patient with Autosomal Dominant Polycystic Kidney Disease (ADPKD) and Caroli's Disease.
We herein present a rare case of an autosomal dominant polycystic kidney disease (ADPKD) patient with Caroli's disease, a congenital embryonic biliary tree ductal plate abnormality often associated with autosomal recessive polycystic kidney disease. A 76-year-old woman with ADPKD on hemodialysis was admitted to our hospital with recurrent cholangitis and hepatobiliary stones. Caroli's disease was diagnosed according to typical imaging findings of cystic intrahepatic bile duct dilatation and the central dot sign. Hepatobiliary system abnormalities such as Caroli's disease should be considered in febrile ADPKD patients, even in the absence of typical clinical signs or symptoms.

Case Reports
Multiple Mesenteric Panniculitis as a Complication of Sjögren's Syndrome Leading to Ileus.
Mesenteric panniculitis (MP) is a benign fibroinflammatory process characterized by the presence of fat necrosis, chronic inflammation and fibrosis in the mesentery. Although various causal factors, such as malignancy, chronic inflammatory conditions and autoimmune processes, have been identified, the precise etiology remains unknown. We herein report a rare case of MP accompanying Sjögren's syndrome in which a mass lesion and intestinal stenosis were observed simultaneously. This condition led to ileus, which was effectively treated using prednisolone.
