Amyloid light-chain (AL) amyloidosis is associated with plasma cell disorder and monoclonal light chains. This type of amyloidosis is the prominent type involving the gastrointestinal tract. Monoclonal gammopathy of undetermined significance (MGUS) is the most common plasma cell disorder and a known precursor of more serious diseases. A 72-year-old male was treated for high blood pressure, diabetes, and gout at the clinic of a private physician. Due to a positive fecal occult blood test discovered during colon cancer screening, he underwent colonoscopy and was diagnosed with adenomatous polyps by biopsies...

It is rare that stage IV colon cancer is cured with chemotherapy. Here we report the long-term survival of a patient who presented with highly advanced disease characterized by a papillary architecture as well as porta hepatis lymph nodes but responded extremely well to FOLFIRI/bevacizumab. His original tumor underwent comprehensive genomic testing that included whole genome DNA sequencing, targeted sequencing, and RNA sequencing. These genetic results suggest the patient's tumor harbored mutations in APC , KRAS , and TP53 as well as in PIK3CB ...

Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) has been utilized as an alternative endoscopic technique for patients with acute cholecystitis. In addition to EUS-guided hepaticogastrostomy and EUS-guided cystogastrostomy, EUS-GBD has been reported as being useful for biliary drainage in cases with distal malignant biliary obstruction instead of conventional endoscopic retrograde cholangiopancreatography. We present a case of successful EUS-GBD for malignant obstruction of an aberrant hepatic duct draining directly into the cystic duct...

We report a very rare case of collision tumor composed of primary adenocarcinoma of the jejunum and gastrointestinal stromal tumor (GIST). The patient was a 63-year-old man who visited our hospital for epigastralgia and vomiting. Abdominal computed tomography revealed a mass in the upper jejunum, with gastric and duodenal dilatation. Endoscopy of the small bowel showed a circumferential tumor in the upper jejunum, which was diagnosed as primary adenocarcinoma by tissue biopsy. Thereafter, partial resection of the small bowel from the third part of the duodenum over the upper jejunum was performed...

A 42-year-old man presented to the emergency room with complaints of periumbilical abdominal pain. A contrast-enhanced computed tomography revealed mucosal thickening in the small bowel of the right abdomen. There was a fairly large small bowel diverticulum associated with this segment. Findings were suggestive of small bowel diverticulitis or possibly focal enteritis. A Meckel's diverticulum scan was diagnostic of Meckel's diverticulum. The patient was then immediately taken to the operating room for emergency laparotomy and was intra-operatively found to have a thickened Meckel's diverticulitis with adjacent small bowel obstruction...

Immune checkpoint inhibitors (ICPIs) are novel therapeutic agents targeting a variety of cancers by enhanced T cell activation. Immune-related adverse events (irAEs) commonly occur with ICPI use and can affect multiple organ systems including the gastrointestinal tract. Due to irAEs, the use of ICPIs is limited in autoimmune diseases. We present a case of microscopic colitis diagnosed after the initiation of nivolumab and a case of ipilimumab colitis and Clostridium difficile in the setting of Crohn's colitis...

#7
Toshiro Sugiyama, Kotaro Arita, Eiji Shinno, Takahiko Nakajima
According to the literature, spontaneous remission of aggressive lymphomas is extremely rare; gastric non-Hodgkin lymphomas, such as mucosa-associated lymphoid tissue lymphomas, often regress due to Helicobacter pylori treatment or no progression, even in a watch-and-wait strategy. Although spontaneous remission of diffuse large B cell lymphomas in the stomach was very rarely reported, the follow-up periods of the cases of spontaneous remission are within 2 years and most cases are likely to relapse after the first remission...

Intramural duodenal hematoma (IDH) is an extremely rare complication after endoscopic biopsy. It typically presents with symptoms due to duodenal obstruction, which include abdominal pain and bilious vomiting. The hematoma may also expand and cause ampullary compression leading to pancreatitis and cholestasis. Computed tomography scan and abdominal ultrasound are the most common diagnostic modalities. Treatment is usually conservative, with bowel rest, nasogastric suctioning and total parenteral nutrition. Refractory cases have been described, requiring endoscopic therapy or surgical drainage...

Clips inserted during laparoscopic cholecystectomy (LC) may migrate into the biliary system and function as a nidus for the formation of gallstones. Here, we present a series of 4 patients who presented with this rare complication 5-17 years after LC. All 4 patients presented with symptomatic choledocholithiasis with biochemical and radiological signs of biliary obstruction. Three patients also had fever and infectious parameters, compatible with concurrent cholangitis. All patients successfully underwent endoscopic retrograde cholangiopancreatography (ERCP) with papillotomy and stone extraction...

We describe the first case of a nonhealing duodenal ulcer with perforation after proton beam therapy (PBT) of a liver tumor that was successfully treated endoscopically using polyglycolic acid (PGA) sheets with fibrin glue. A 69-year-old man received PBT for a liver tumor. Esophagogastroduodenoscopy (EGD) 3 months after PBT revealed a duodenal ulcer. A proton pump inhibitor was administered for 7 weeks, and the ulcer healed. Six months after the EGD, recurrence of the duodenal ulcer with perforation occurred...

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract (GIT). In fewer than 5% of cases, GIST originates primarily from outside the GIT. The occurrence of GIST originating from the pancreas is rare. Sometimes, neuroendocrine tumors should be differentiated from GISTs because of their hyperenhancing nature in radiologic images. We report a case of GIST arising in the pancreas that was confirmed by surgical resection.

#12
James E Heubi, Warren P Bishop
Zellweger spectrum disorders (ZSDs) are a subgroup of peroxisomal biogenesis disorders with a generalized defect in peroxisome function. Liver disease in ZSDs has been associated with the lack of peroxisomal β-oxidation of C27 -bile acid intermediates to form primary C24 -bile acids, which prevents normal physiologic feedback and leads to accumulation of hepatotoxic bile acid intermediates. Primary bile acid therapy, oral cholic acid (CA), as adjunctive treatment for ZSDs, restores physiologic feedback inhibition on bile acid synthesis and inhibits formation of hepatotoxic bile acid intermediates...

Several possible mechanisms for spontaneous regression of hepatocellular carcinoma (HCC) have been reported. Spontaneous complete regression of HCC is extremely rare. We herein report a case of spontaneous pathological complete regression of HCC following decrement of elevated serum alpha-fetoprotein (AFP). The serum AFP of a 74-year-old man who underwent hepatic resection for HCC twice increased up to 7,529 ng/mL and then spontaneously decreased to 404 ng/mL in 2 months. Computed tomography, magnetic resonance imaging, and angiography revealed a liver tumor in segment 7 without early enhancement...

The finding of a vermiform appendix in the case of an inguinal hernia that extends below the midpoint of the inner thigh when the patient is in a standing position is defined as giant left-sided Amyand's hernia. It is a very rare case and significantly challenging in terms of preoperative diagnosis and surgical management. Here we present our experience with a case of a giant left-sided Amyand's hernia that was followed up for 2 months.

Mixed connective tissue disease (MCTD) is a rare connective tissue disorder with clinical features that overlap with systemic lupus erythematous, systemic sclerosis, and polymyositis. We report the case of a patient who presented with dysphagia, 25-lb weight loss, difficulty opening her mouth, and joint pain. Dysphagia workup showed a normal barium swallow and normal-appearing EGD but esophageal manometry consistent with severe dysmotility. Through further laboratory and imaging studies, the patient met the diagnostic criteria for MCTD...

Extraintestinal Clostridium difficile infection (CDI) is extremely uncommon. High mortality and poor outcomes have been observed among individuals with this rare medical condition. Empyema is one of the extraintestinal manifestations of CDI. Possible mechanisms to develop this parapneumonic effusion are aspiration and contamination of the chest tube. We present a 42-year-old Hispanic male with C. difficile empyema without any prior history of CDI.

Around 8% of patients diagnosed with sickle cell disease (SCD) are hepatitis C virus (HCV) carriers. Previously, HCV treatment was seldom considered in SCD patients, as the ribavirin-induced hemolysis and interferon-induced cytopenias could lead to more profound anemia. Nowadays, several oral direct-acting antiviral drugs have been developed and approved by the FDA for hepatitis C treatment. While direct-acting antivirals mitigate many of these risks, their safety and efficacy in SCD patients remains insufficiently explored...

Dermatomyositis (DM) is often found in conjunction with malignant tumors such as lung, cervical, and breast cancer. However, the association with intrahepatic cholangiocarcinoma (ICC) is extremely rare. Moreover, to our knowledge, there have been no previous reports of DM discovered because of exacerbation of DM. Our case was a 44-year-old female with dry cough, myalgia, and arthralgia. We performed hepatic resection for intrahepatic ICC. She was diagnosed with DM, and combination treatment with prednisolone and tacrolimus was started...

Ixekizumab is a selective monoclonal antibody targeting interleukin-17A, approved for the treatment of chronic plaque psoriasis. It has rarely been associated with inflammatory bowel disease (IBD) in randomized trials only. We report a unique case of severe new-onset ulcerative colitis in a young male complicated by cytomegalovirus infection who was on ixekizumab therapy for plaque psoriasis. We recommend that clinicians should exercise caution before prescribing ixekizumab as it seems to induce and exacerbate IBD...

Inflammatory bowel disease (IBD) affects young people of reproductive age. Therefore, a broad discussion is needed about the possible disease effects in pregnancy, as well as the risks of fetal exposure to the medications used, especially biological therapy. This study aimed to describe the management of 4 Crohn's disease patients who received anti-TNF therapy during pregnancy and present a literature review. We reported 4 cases composed of young women who became pregnant while receiving anti-TNF agents. The patients presented a satisfactory response to the clinical treatment and the pregnancies progressed without complications...
