RESUMEN
Nephrotic syndrome is characterized by hypercoagulability and thrombosis of the renal and deep veins. We describe a case of unusual thrombosis in the portal and superior mesenteric veins of a 41-year-old female, admitted for treatment of abdominal pain, who simultaneously presented with nephrotic syndrome and acute pancreatitis. Laboratory analysis revealed hypoalbuminemia, hyperlipidemia, and proteinuria. Abdominal computed tomography revealed acute pancreatitis, thrombosis at the portal and superior mesenteric veins, and ischemic changes in the colon and small intestines. Anticoagulation therapy was started immediately. Abdominal pain was subsequently reduced and the ischemic lesion disappeared. Warfarin use could not be terminated immediately. Empirical steroid therapy commenced without a kidney biopsy. Complete remission occurred after 4 weeks. Following warfarin cessation, a kidney biopsy was performed, confirming the diagnosis of minimal change disease.

A 58-yr-old man presented with leg edema and subacute weakness of his bilateral lower extremities. Urinary and serum immunoelectrophoresis revealed the presence of lambda-type Bence Jones proteins. He was ultimately diagnosed with monoclonal gammopathy of undetermined significance (MGUS). A renal biopsy specimen showed fibrillary glomerulonephritis (FGN), which was randomly arranged as 12-20 m nonbranching fibrils in the basement membranes. Immunofluorescence studies were negative for immunoglobulin (Ig)G, IgM, IgA, C3, and kappa light chains in the capillary walls and mesangial areas. A Congo red stain for amyloid was negative. Electromyography and nerve conduction velocity examinations results were compatible with the presence of demyelinating polyneuropathy. This case showed a rare combination of FGN, without Ig deposition, and MGUS combined with chronic inflammatory demyelinating polyneuropathy (CIDP).

Renal cell carcinoma (RCC) is the second most common urological malignancy and it has diverse range of clinical manifestation. One third of the patients show the metastasis at the time of the diagnosis. The common sites of metastasis are the lung, bone, lymph nodes and metastasis to the pancreas is rare. In case of pancreatic metastasis, more than half of the patients are asymptomatic. Patients with symptoms visit hospital complaining of abdominal pain, weight loss, steatorrhea and rarely biliary obstruction. Although about 40% of all patients visit hospital with hemorrhage, cholangitis caused by spontaneous pancreatic hemorrhage is rare. We report an interesting case of 61-year-old woman with cholangitis caused by bleeding due to pancreatic metastasis from renal cell carcinoma.
