Eosinophilic enterocolitis: a case report.

BACKGROUND: Eosinophilic enterocolitis is a rare disorder characterized by abnormal eosinophilic infiltration of the small intestine and the colon. CASE PRESENTATION: We report a case of a 29-year-old White man, who presented with an acute bowel obstruction. He had a history of a 2 months non-bloody diarrhea. An abdominal computed tomography (CT) and a MR enterography showed a multifocal extensive ileitis. White blood cell and eosinophilic polynuclei count was elevated (700/mm3). Ileo-colonoscopy showed normal ileum and segmental petechial colitis. Pathology showed a high eosinophilic infiltration in the colon. The patient was treated with steroids, with a clinical, biological and radiological recovery. CONCLUSION: Eosinophilic enterocolitis should be kept in mind as a rare differential diagnosis in patients presenting with small bowel obstruction.

Abdominal unicentric Castleman's disease: a case report.

Castleman's disease is a rare disease characterized by benign lymphoepithelial proliferation. There are two forms: unicentric and multicentric Castleman's disease. Mediastinal location is the most frequent. Intra-abdominal Castleman's disease is a rare presentation. We report a case of 65-year-old female who presented with epigastric pain. Investigations revealed a retroperitoneal mass which was surgically resected. Histopathological examination showed hyaline-vascular type Castleman's disease. In conclusion, Castelman´s disease is a diagnostic challenge and it must be included in the differential diagnosis of retroperitoneal tumors.

Intestinal pseudo-obstruction: Unusual presentation of systemic lupus erythematous.

Systemic diseases should be always considered when managing unexplained intestinal pseudo-obstruction. Intestinal pseudo-obstruction related to systemic lupus erythematosus is often responsive to corticosteroid therapy when promptly treated.
