    Helicobacter Pylori-Negative MALT Lymphoma: A Series of Two Cases Presenting with Life-Threatening Upper Gastrointestinal Bleeding
    Kim, Seo Hyun; Soliman, Youssef; Chitnavis, Vikas N.; Chitnavis, Maithili V. (Hindawi, 2023-03-23)
    Mucosa-associated lymphoid tissue (MALT) lymphoma is a common cause of gastric lymphoma. Although most cases are associated with an H. pylori infection, approximately 10% are H. pylori-negative. Patients with gastric MALT lymphoma are usually asymptomatic or present with nonspecific symptoms such as abdominal pain, dyspepsia, weight loss, and occult gastrointestinal bleeding. In this report, we describe two patients with H. pylori-negative MALT lymphoma who both presented with acute upper gastrointestinal bleeding that led to hemodynamic instability. After resuscitation, emergent endoscopy was performed. Both patients had the t (11; 18) (q21; q21) translocation, which prompted direct treatment by radiotherapy.

    A Rare Case of Eosinophilic Gastroenteritis Isolated in the Muscularis Propria of the Small Bowel
    Kim, Seo Hyun; Kesar, Varun; Grider, Douglas; Nguyen, Vu (Cureus, 2021-10-14)
    Eosinophilic gastroenteritis (EG) is an autoimmune disorder that involves infiltration of eosinophils in the bowel wall of the stomach and/or intestine, resulting in various gastrointestinal symptoms. The majority of cases are diagnosed by findings of increased eosinophils on mucosal biopsies. We describe a rare type of eosinophilic gastroenteritis with eosinophilic infiltration involving only the muscularis propria layer. This elusive diagnosis was made after a full-thickness intestinal wall biopsy. This predominantly muscular type eosinophilic gastroenteritis can cause intestinal obstruction or perforation. Similar to the predominantly mucosal type eosinophilic gastroenteritis, this type of eosinophilic gastroenteritis responds to low-dose or topical corticosteroids.

    A Rare Case of Typhoid Fever in the United States Associated With Travel to Mexico
    Kim, Seo Hyun; Bansal, Jash (Cureus, 2022-02-17)
    Typhoid fever is an infectious febrile illness caused by Salmonella typhi that is rare in the United States but is endemic in regions of South Asia and Africa. Typhoid fever initially presents with nonspecific symptoms such as fever, malaise, and abdominal pain. We describe a case of typhoid fever in an adult in the United States with recent travel to Mexico. After a nonspecific presentation, the patient developed Faget sign and computed tomography (CT) of the abdomen revealed mesenteric adenitis, which prompted additional workup. Diagnosis of typhoid fever was established by blood culture and the patient was treated with ciprofloxacin.
