Diverticulitis associated pancreatitis: a report of 2 cases and review of the literature.

Duodenal diverticula are the second most common type of digestive diverticula after those in the colon. They are present in approximately 27% of patients who undergo upper digestive endoscopy. Most of these diverticula, especially those located near the papilla, are asymptomatic.

Rectal plasmablastic lymphoma in Ebstein Barr virus positive and human immunodeficiency virus negative subject after external radiation therapy for prostatic cancer.

Plasmablastic lymphoma (PBL) represents a rare and aggressive subtype of diffuse large B cells lymphoma (DLBCL) most associated with the human immunodeficiency virus (HIV). Prognosis remains poor despite various treatment approaches. We describe an evolution at six months of HIV negative PBL and Ebstein Barr virus (EBV) positive PBL with chemotherapy.

[Rectal giant inflammatory pseudopolyps : an unusual cause of rectal bleeding].

Giant inflammatory pseudopolyps are begnin lesions that have been described usually in patients with inflammatory bowel disease. Rarely, they have been reported in patient without any colonic disease. We report the case of a 40-old woman, without previous colonic pathology, who presented with rectal giant inflammatory pseudopolyps revealed by rectal bleeding.

[Gallbladder metastasis from breast carcinoma: a new case report].

The breast carcinoma metastases preferentially in the axillary lymph nodes, bones, lungs, liver and soft tissues. Gastrointestinal or bladder dissemination is very rare. We report the case of a 63-year-old female with a clinical presentation of acute cholecystitis, who underwent laparoscopic cholecystectomy in emergency.

Nodular sclerosing Hodgkin's disease mimicking Riedel's invasive fibrous thyroiditis.

Riedel's thyroiditis appears in the form of a hard cervical mass with rapid onset, and it is associated with extensive fibrosis that compresses nearby structures, such as the trachea and supra-aortic vessels; its diagnosis is essentially histopathological. Although its histological characteristics have been well established, there are some diagnostic pitfalls. We report here the case of a 37-year-old woman, with clinical and histopathological data suggesting Riedel's disease.
