Patients with chronic renal failure (CRF) are known to be more susceptible to tuberculosis infection due to impairment of the host defense mechanism. Although extrapulmonary tuberculosis is more prevalent in those subjects and it may induce dismal outcome, its diagnosis has been challenging since there is no specific symptoms of the disease and the clinical course is usually atypical. Herein, We report a case of disseminated tuberculosis diagnosed by ultrasound-guided liver biopsy in a 31-year-old CRF patient presenting sustained fever despite broad-spectrum antimicrobial therapy and progressive cholestatic jaundice.

Double primary cancers are two independently developed cancers in an individual. There have been some reports on double primary cancer since Billroth reported it for the first time in 1879. Double primary cancer of the stomach and esophagus has been revealed a very low incidence worldwide. The incidence of an esophageal cancer with another primary cancer is reported to be 9.5~27%, but double primary cancers in the esophagus and stomach have been rarely reported to our knowledge. In this study, we present here a case of double primary esophageal and stomach cancer in a 66-year-old man because of progressive dysphagia.

Gastrointestinal stromal tumors (GISTs) are common mesenchymal tumors that arise in the wall of the gastrointestinal tract. We report a case of obscure gastrointestinal bleeding due to a GIST of the jejunum successfully documented by videocapsule endoscopy (VCE) and single-balloon enteroscopy (SBE). A 36-year-old man with hematochezia was referred for further evaluation of no evidence of bleeding focus on esophagogastroduodenoscopy and colonoscopy. A VCE showed a suspicious ulcerative hyperemic mass that located in about 1 hour apart from duodenal second portion. SBE revealed a nonbleeding 4×2 cm mass with an ulcer at the proximal jejunum. The patient underwent laparoscopic resection without complication. Histological examination revealed a well circumscribed, dumbbell-shaped firm mass comprised of spindle cells. Immunohistochemical staining for CD 117 was diffusely positive, whereas staining for S-100, CD 34 and MIB-1 was all negative. It was confirmed to be a low-grade GIST at the proximal jejunum.
