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. However, in rare cases, they can be associated with obstructive jaundice (Lemmel Syndrome), bacterial infection, pancreatitis, or bleeding. In this report, we present two cases of acute obstructive pancreatitis caused by duodenal diverticulitis. Both patients were managed conservatively, resulting in a positive outcome.

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. Role of radiotherapy is still unclear.

[Rectal giant inflammatory pseudopolyps : an unusual cause of rectal bleeding]. / Pseudo-polypes inflammatoires géants du rectum : une cause rare de rectorragies.

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.

Les pseudo-polypes inflammatoires géants sont des tumeurs bénignes du tube digestif. Ils ont principalement été décrits chez les malades atteints de maladie inflammatoire chronique de l'intestin. Exceptionnellement, ils ont été rapportés chez des patients n'ayant aucune pathologie digestive. Nous rapportons l'observation d'une patiente de 40 ans, présentant de multiples pseudo-polypes inflammatoires géants du rectum, en l'absence de toute autre pathologie colorectale, révélés par des rectorragies.

[Gallbladder metastasis from breast carcinoma: a new case report]. / Métastase vésiculaire d'un carcinome mammaire: une nouvelle observation.

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. The gallbladder showed a nodule at the infundibulum, which was responsible for the gallbladder hydrops with macroscopic features of a cholangiocarcinoma. Histological examination disclosed a metastasis from a lobular breast carcinoma with positive hormone receptors, but no overexpression of the Neu oncogene. Immunohistochemistry showed positive staining for cytokeratin7 suggesting a lesion of breast origin. The absence of E-cadherin was consistent with lobular carcinoma while negative CA 19.9 excluded cholangiocarcinoma. The patient had received 15 years previously a right mastectomy with axillary dissection followed by chemotherapy and radiotherapy for breast carcinoma of ductal type labeled SBR stage III, pT3N1 M0, showing hormone receptors but absent Neu oncogene. Proofreading of the mastectomy histological slide concluded that it was a lobular rather than a ductal type carcinoma, confirming the finding of a gallbladder metastasis 15 years after the mastectomy. The patient showed no local recurrence or contralateral lesions on magnetic resonance imaging (MRI). The bone scan showed metastases in the skull, scapula, right rib cage, thoracolumbar spine and pelvis, also confirmed by MRI. A treatment with exemestane and zoledronic acid was introduced. The follow-up at 6 months showed regression of the bone lesions and absence of parenchymal new locations.
