[Esophageal tuberculosis in an immunocompetent patient]. / Tuberculosis esofágica en paciente inmunocompetente.

We present the case of a 68-year-old man who presented dysphagia and weight loss over the previous three months. Esophageal transit showed extreme stenosis suspicious for neoplasia but which was revealed to be a granulomatous inflammatory lesion. Culture of the lesion revealed Mycobacterium tuberculosis. Chest x-ray showed pulmonary tuberculosis. Esophageal tuberculosis should be considered in patients with dysphagia and pulmonary tuberculosis.

[A case of non Hodgkin Lymphoma in a patient with hepatic cirrhosis by the hepatitis C virus]. / Un caso de linfoma no hodgkiniano en una paciente con cirrosis hepática por el virus de la hepatitis C.

We present a case of non-Hodgkin's lymphoma of B cells in a patient with cirrhosis by hepatitis C virus. Our patient presented scarce symptomatology related with non-Hodgkin's lymphoma. A notable hyperbilirrubinaemia with hypoalbuminaemia were the only features that allowed us to suspect the diagnosis. The diagnostic was proved by necroscopic study. There are several factors involved in the etiology of non-Hodgkin's lymphoma, including infectious agents. Recent Italian studies have suggested an association between C virus infection and non-Hodgkin's lymphoma. We have carried out a bibliographical revision of this association to conclude that important geographical differencies must be pointed out.

[Gastrointestinal hemorrhage secondary to a pancreatic pseudoaneurysm]. / Hemorragia digestiva secundaria a un seudoaneurisma pancreático.

Acute hemorrhage from pancreatic pseudoaneurysm is the most rapidly fatal complication of pancreatitis, with a reported mortality rate of > 90% in untreated patients. The diagnosis of pancreatic pseudoaneurysm requires a high index of suspicion and the abdominal angiography is the gold standard. Transcatheter embolization is an alternative to surgery for treatment in selected patients. Early diagnosis and treatment decrease the mortality dramatically. We describe a patient with a gastrointestinal bleeding from a ruptured pancreatic pseudoaneurysm, with an angiography diagnosis and transcatheter embolization. We treated the pseudocyst with an endoscopic drainage. A review of literature is presented.

[Chronic calcifying pancreatitis and extracorporeal pancreatic lithotripsy]. / Pancreatitis crónica calcificante y litotripsia pancreática extracorpórea.

Abdominal pain is the most frequent symptom of chronic pancreatitis and may, on occasions, lead to great treatment problems. The case of a 35-years-old patient diagnosed with chronic calcifying pancreatitis of enolic etiology who showed dilatation of the main pancreatic duct and intracanalicular lithiasis is reported. Medical, endoscopic and surgical alternatives failed but fragmentation of the lithiasis by extracorporeal lithotripsy was successful.
