Endoscopic Resection of a Cavernous Hemangioma in the Sigmoid Colon: A Case Report.

Hemangiomas in the gastrointestinal tract are extremely rare, benign vascular tumors, known for their associated complication of bleeding. They are usually difficult to diagnose, despite the characteristic definition of radiolucent phleboliths on radiology and purplish, tannish brown nodule or polyp on endoscopy. Surgical resection is the treatment of choice. We describe a rare case of sigmoid colon cavernous hemangioma in a 49-year-old male who underwent colonoscopy for lower abdominal pain and revealed a large pedunculated polyp in the sigmoid colon measuring 1.7 cm in diameter. The hemangioma was completely resected endoscopically via hot snare with a favorable outcome.

Primary Gastric and Duodenal Mucosa-Associated Lymphoid Tissue Lymphoma With Symptomatic Anemia.

Mucosal-associated lymphoid tissue (MALT) is a low-grade lymphoma derived from marginal zone B cells in extranodal tissue. Gastric MALT lymphoma is frequently seen; however, duodenal MALT lymphoma is rare, and there is no standardized knowledge up to date about the management of the disease. We present a case of a 56-year-old woman with gastric and duodenal MALT lymphoma.

The Efficacy, Tolerance, and Adverse Events of Endoscopic Intragastric Balloon in Obese and Overweight Patients: A Retrospective Cross-Sectional Study.

Introduction Obesity is a pandemic causing a significant burden on healthcare systems and carries increased morbidity and mortality. One of the options for managing obesity is endoscopic intragastric balloon (IGB) insertion. The aim of the study is to assess the efficacy, tolerance, and side effects of IGB insertion in overweight and obese patients. Methods This is a cross-sectional retrospective study that includes 71 patients who underwent IGB insertion from 2015 to 2019 at King Hamad University Hospital (KHUH), Kingdom of Bahrain. Records of these patients were accessed to assess the percentage of weight loss at the time of balloon removal, complications, and tolerance of the procedure. Furthermore, telephonic interviews were conducted to enquire about side effects and the satisfaction of the procedure. Results A total of 57 patients were included in the weight loss analysis. Thirteen patients did not tolerate the balloon, and one patient had a balloon rupture. The patients experienced a significant reduction in weight upon balloon removal with a mean of 9.74 ± 8.71 kg (p-value of <0.001) and percentage total body weight loss of 10.48 ± 8.07 (p-value of <0.001). A significant reduction was also seen in the body mass index of 3.67 ± 3.57 (p-value of <0.001). The most frequent side effects were nausea, vomiting, and abdominal pain. No major complications or mortalities occurred. Conclusion Intragastric balloons are effective in establishing weight loss. Among patients who tolerated the procedure, the most frequently reported side effects were nausea, vomiting, and abdominal pain.

Duodenal-Type Follicular Lymphoma.

This case report presents the clinical findings, diagnostic evaluation, and treatment options for a 71-year-old female patient with a medical history of hypertension, dyslipidemia, and recurrent urinary tract infections. The patient presented with chronic abdominal pain as the sole symptom. Despite normal laboratory investigations, esophagogastroduodenoscopy and ileocolonoscopy were performed. Biopsies were obtained from the duodenum and histopathological analysis confirmed a diagnosis of duodenal-type follicular lymphoma. This rare condition typically presents with minimal clinical symptoms and has a favorable prognosis. Treatment options for duodenal-type follicular lymphoma include a watch-and-wait strategy, rituximab monotherapy, and radiotherapy.

Plasmacytoid Carcinoma in Gastrointestinal Tract, Rare Case Presentation.

Plasmacytoid carcinoma is a proliferation of discohesive cells. Gastrointestinal tract plasmacytoid carcinomas, whether primary or metastatic in origin, are both very rare. Immunohistochemistry plays a crucial role in localization. We present a case of a 60-year-old female, known case of left breast invasive lobular carcinoma with gastric, duodenal, and colonic plasmacytoid adenocarcinoma.

An Incidental Finding of Gastric and Duodenal Pseudomelanosis: A Case Report.

Pseudomelanosis of the upper gastrointestinal tract is a rare diagnosis of undetermined significance, most commonly affecting the duodenum. Endoscopically, it is characterized by dark spickled pigmentation . Its development has been linked to certain conditions and medications. Involvement of the stomach is extremely rare with very few cases reported in the literature to date. We report an 85-year-old male who is known to have type 2 diabetes mellitus, dyslipidemia, iron deficiency anemia, and chronic kidney disease who underwent an esophagogastroduodenoscopy for evaluation of upper gastrointestinal bleeding and was found to have gastric and duodenal pseudomelanosis confirmed by biopsy. It is an extremely rare benign condition, but metastatic melanoma has to be ruled out, as was done in this case.
