Acute adomen in a transplant patient with tuberculous colitis: a case report.

Introduction: Tuberculous colitis is a rare form of tuberculosis and is found in immunosuppressed patients, usually with the clinical appearance of Crohn's disease. The purpose of this article is to report a rare case of tuberculous colitis in a transplant patient, presenting in the form of bowel obstruction and acute abdomen.

Methods: A male patient, 51 years old, with a history of kidney transplant in a foreign country 19 months before, presented at the emergency department, after being referred by a primary care center, with obstipation during the previous week and acute abdominal pain.

Mucinous adenocarcinoma of the appendix presenting with atypical symptomatology and presence of pseudomyxoma peritonei: a case report.

Introduction: Primary tumors of the appendix are unusual and most of them are carcinoids. Their main presentation is that of an acute appendicitis or as a palpable mass, mainly in the right lower quadrant.

Case Presentation: A female patient with mucous adenocarcinoma of the appendix, which primarily presented as atypical abdominal pain.

Subcutaneous emphysema, pneumomediastinum and pneumoperitoneum after unsuccessful ERCP: a case report.

Background: The presence of subcutaneous emphysema, pneumomediastinum and pneumoperitoneum simultaneously is a rare complication of upper gastrointestinal endoscopy that usually indicates free perforation to the peritoneal cavity or the retroperitoneal space.

Case Presentation: We report an unusual case of a self-limited subcutaneous emphysema, pneumomediastinum and pneumoperitoneum following an unsuccessful ERCP for removal of a common bile duct stone.

Conclusion: There was no radiological evidence of peritoneal or retroperitoneal perforation.

Schistosomal peritonitis: a rare cause of acute abdomen.

Schistosomiasis is a major parasitic infection of tropical areas. We present a 26-year-old male immigrant from Egypt with acute abdomen due to schistosomial infection, mimicking symptoms of acute appendicitis, with histopathological detection and representation of schistosomial eggs in the unusual area of the greater omentum. This is a rare case with findings of intra-peritoneal schistosoma ova.
