Esophageal Schwannoma: A Rare Benign Esophageal Tumor.

Cureus 2021 Jun 15;13(6):e15667. Epub 2021 Jun 15.

Gastroenterology, Riverside Medical Clinic, Riverside, USA.

Benign primary tumors are uncommon, with the majority of these tumors being leiomyomas; schwannomas of the esophagus are rare. Here, we present a case of a 78-year-old woman referred for complaints of intermittent dysphagia with a chest computed tomography scan showing a homogenous mass, compressing the esophagus. Upper gastrointestinal endoscopy revealed a submucosal mass, which was eventually diagnosed as a schwannoma after an endoscopic ultrasound with fine-needle aspiration and subsequent pathologic and immunohistochemical examination. Schwannomas could be managed conservatively.

A Curious Case of Acute Acalculous Cholecystitis.

Cureus 2021 May 10;13(5):e14948. Epub 2021 May 10.

Internal Medicine, University of California Los Angeles, Los Angeles, USA.

Acute acalculous cholecystitis is inflammation of the gallbladder without any evidence of gallstones. Although acalculous cholecystitis is less common than its calculous counterpart, it can be fatal if not treated. It is essential to rule out the cause of acalculous cholecystitis to aid in the treatment and management of the patient. We present a case of acalculous cholecystitis wherein a comprehensive workup found the etiology to be viral. Albeit rare, hepatitis A and cytomegalovirus can be causes of acute cholecystitis. Both viruses were observed simultaneously in this patient, proving it to be a unique case. This early diagnosis allowed conservative management of the patient, sparing him from unnecessary surgical intervention.

Kratom-Induced Liver Injury: A Case Series and Clinical Implications.

Cureus 2021 Apr 25;13(4):e14679. Epub 2021 Apr 25.

Internal Medicine, Riverside Community Hospital/University of California (UC) Riverside, Riverside, USA.

Drug-induced liver injury (DILI) is among the most common causes of acute liver injury and acute liver failure in the United States. Kratom is an herbal supplement made from the leaves of a tropical evergreen tree (Mitragyna speciosa) that is native to Southeast Asia. Due to its psychotropic and opioid-like activity, there has been an increase in its use as a recreational drug. Despite this increase, little is known regarding the toxicities and adverse effects though it is known to cause DILI. We present two cases of DILI associated with Kratom use.

Primary Duodenal Periampullary Adenocarcinoma: An Uncommon Presentation.

Cureus 2021 Apr 6;13(4):e14323. Epub 2021 Apr 6.

Internal Medicine, University of California, Riverside School of Medicine, Riverside, USA.

Periampullary carcinoma is a broad term used to define the group of carcinomas arising from the head of the pancreas, the distal common bile duct, and the duodenum. It is clinically important to differentiate ampullary from periampullary carcinoma as this can affect resectability and prognosis. Atypical left-sided chest pain is an atypical presentation of periampullary duodenal adenocarcinoma. A 58-year-old man presented with a two-month duration of worsening intermittent, atypical, migratory left-sided chest pain. Imaging studies were unremarkable; however, endoscopic evaluation demonstrated a duodenal mass. While most periampullary carcinomas are generally curable with pancreaticoduodenectomy, if left untreated, these tumors are uniformly fatal.

Transhiatal Herniation as the Cause of Acute Pancreatitis After Toupet Fundoplication.

ACG Case Rep J 2019 Aug 14;6(8):e00156. Epub 2019 Aug 14.

Internal Medicine Residency, Graduate Medical Education, Riverside Community Hospital/University of California, Riverside School of Medicine, Riverside, CA.

Hiatal translocation of the pancreas is rare because of its retroperitoneal location. Acute pancreatitis as a complication of hiatal hernia is uncommon. A 33-year-old man presented for 2 days of worsening epigastric abdominal pain and substernal chest pain. Laboratory studies were essentially unremarkable; however, computed tomography demonstrated a large right-sided hiatal hernia containing the entire stomach and the body of the pancreas, with peripancreatic edema consistent with pancreatitis. Most cases can be managed conservatively; however, elective surgical repair is suggested in severe cases or patients with low surgical risk.
