High grade Burkitt lymphoma in an immunocompetent young patient: Concomitant gastric and ileal localizations.

Burkitt lymphoma is a highly aggressive and rapidly growing B cell non-Hodgkin lymphoma with heterogeneous pattern of manifestations. We present a rare case of a 39-year-old immunocompetent male with double localization of Burkitt lymphoma: gastroduodenal and ileal tract. The gastric location is extremely rare, and the association with another site is unusual with only few reports in the literature. Imaging modalities play a crucial role in correct diagnosis as it can manifest as a focal mass or as segmental wall thickening. Radiologists should recognize common and uncommon presentations and sites of Burkitt lymphoma given the urgency of potential treatment, in order to improve the patient's prognosis.

Endoscopic management of anastomotic leakage after colorectal cancer surgery in a Moroccan center: A case series and literature review.

Endoscopic management has become an alternate treatment to a revision surgery for colorectal fistulas. Eight patients who were treated by endoscopy for postoperative anastomotic leakage to colorectal cancer were included. A univariate analysis was carried out to determine the predictive factors of success. All our patients were treated using metallic clips. The primary efficiency of this technique was 50%. In a univariate analysis, the size of the fistula and its distance from the anal margin had an influence on the efficiency of the endoscopic treatment, which was not the case for either the surgical technique or the use of neoadjuvant radiotherapy. This endoscopic treatment is effective and represents a more secure alternative than revision surgery. In our study, the use of metallic clips showed a 50% success rate, going up to 100% for the group of patients with a fistula ostium of a size ⩽1 cm, proving the necessity of using this technique.

Massive brown tumors of the jaw: A case report.

Brown tumors are non-neoplastic bone lesions caused by an abnormal remodeling of the bone that may occur with primary or secondary hyperparathyroidism. Their radiological aspect: lytic and aggressive can easily be misdiagnosed for a malignant origin hence the importance of knowing that diagnosis is to be considered through both clinical context and radiological semiology, which will be detailed via this case of a 32-year-old female patient with an end-stage kidney disease, admitted for facial disfiguration and palpable masses corresponding to brown tumors affecting the maxilla and the mandibular bone.

Infected Biloma after Endoscopic Ultrasound-Guided Fine-Needle Aspiration.

Biloma is a severe complication that can result from bile duct disruption or hepatic trauma. It can occur after biliary surgery such as cholecystectomy or an endoscopic retrograde cholangiopancreatography manipulation and endoscopic biliary sphincterotomy. We present the case of a 59-year-old man admitted for jaundice, with pain in his right flank and fever, 10 days after an endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for an ill-defined pancreatic lesion, associated with an infected biloma. Severe complications can occur after an EUS-FNA; therefore, this diagnosis should not be neglected after the intervention in symptomatic patients, to ensure an early and proper treatment.

Large Cystic Mass of the Pancreatico-Duodenal Region Revealing Duodenal Lymphatic Malformation: A Case Report.

Lymphatic malformations are benign tumors rarely located in the gastro-intestinal tract. They are usually asymptomatic; however, they can cause clinical discomfort when enlarged. Imaging leads to diagnosis, but the confirmation can only be done through histology findings. We report the case of a 59-year-old male patient, admitted in our ward for melena, to which esophago-gastroduodenoscopy showed budding formations in the second portion of the duodenum wall, with Magnetic Resonance Imaging features and histological examination confirming diagnosis of a duodenal lymphatic malformation.

An Unusual Cause of Biliary Tract Obstruction: Lemmel Syndrome.

BACKGROUND: Lemmel syndrome is a rare and misdiagnosed etiology of obstructive jaundice due to a periampullary duodenal diverticulum causing a mechanical obstruction of the common bile duct. It represents an obstructive jaundice with the absence of choledocholithiasis or pancreaticobiliary tumors. It is an underreported entity due to the absence of specific pathognomonic signs. CASE PRESENTATION: A 77-year-old-woman admitted for sepsis, due to an ascending cholangitis, underwent a MRCP and a gastroduodenoscopy revealing Lemmel's syndrome. Due to failure of ERCP, the patient underwent surgical derivation. CONCLUSION: Lemmel syndrome represents an uncommon diagnosis of obstructive jaundice, that shouldn't be neglected if no other organic cause is detected. It is usually asymptomatic, however some patients can develop symptoms and complications such as cholangitis, as is the case of our patient. Imaging allows diagnosis, with MRCP as the modality of choice to confirm diagnosis. Endoscopy is the first line treatment.
