An Atypical Presentation of Metastatic Renal Cell Carcinoma.

Renal cell carcinoma (RCC) is notorious for spreading to various organs, however, its occurrence in the gastrointestinal (GI) tract is uncommon and poses diagnostic challenges due to vague symptoms. Here, we present the case of a 64-year-old man experiencing recurrent RCC metastasis in the GI tract. He presented with multiple episodes of hematochezia and was found to have masses in the colon, liver, and peritoneum, with histopathology confirming RCC. The patient underwent systemic chemotherapy and palliative radiation therapy, leading to symptom relief. This case emphasizes the rarity of RCC metastasizing to the GI tract and the importance of timely recognition and frequent surveillance during the remission phase to detect recurrence.

Primary Diffuse Large B-cell Lymphoma of the Colon Presenting as Idiopathic Thrombocytopenia: A Case Report.

Introduction: Primary lymphoma of the colon and rectum is an uncommon form of cancer comprising less than 0.5% of all colorectal tumors combined. Typically, extra nodal lymphomas manifest in the gastrointestinal tract, with non - Hodgkin lymphoma being the most frequent subtype and the stomach being the most common location. Case presentation: 70 year old female with medical history of osteoarthritis and osteoporosis was evaluated for bilateral leg rash and thrombocytopenia. Eventual work up revealed cecal mass but inconclusive findings on colonoscopy. She underwent hemicolectomy due to persistent thrombocytopenia with histopathology positive for primary Diffuse Large B-cell Lymphoma (DLBCL). She underwent chemotherapy with complete resolution of her mass and lymphadenopathy. Conclusion: We are presenting a rare case of Non - Hodgkin lymphoma in the colon. This disease can show up with unclear symptoms, so it's important to use different types of imaging and pathology tests to identify the specific type of lymphoma. The main treatment for this type of cancer involves using chemotherapy and radiation therapy.

Pylephlebitis-induced acute liver failure: A case report and review of literature.

BACKGROUND: Pylephlebitis is an extremely rare form of septic thrombophlebitis involving the portal vein, carrying high rates of morbidity and mortality. CASE SUMMARY: We present a case of a 42-year-old male with no past medical history who presented with acute onset of abdominal pain and altered mental status with laboratory tests demonstrating new-onset acute liver failure. Pylephlebitis was determined to be the underlying etiology due to subsequent workup revealing polymicrobial gram-negative anaerobic bacteremia and complete thrombosis of the main and left portal veins. To our knowledge, this is the first documented case of acute liver failure as a potential life-threatening complication of pylephlebitis. CONCLUSION: Our case highlights the importance of considering pylephlebitis in the broad differential for abdominal pain, especially if there are co-existing risk factors for hypercoagulability. We also demonstrate that fulminant hepatic failure in these patients can potentially be reversible with the immediate initiation of antibiotics and anticoagulation.

Chronic Pancreatitis-Induced Thrombosis of Celiac and Superior Mesenteric Artery.

Every year, nearly 60,000 hospitalizations occur in the United States due to chronic pancreatitis (CP). CP can cause severe chronic abdominal pain, pancreatic insufficiency, and increased risk of pancreatic cancer. While venous thrombotic complications are common, arterial thrombotic events are rarely reported in CP. This report describes a case of a 43-year-old female who presented with severe worsening abdominal pain due to CP. Diagnostic imaging disclosed thrombosis of superior mesenteric artery (SMA) and celiac artery (CA) with acute bowel wall changes reflecting ischemic changes, resulting in acute-on-chronic mesenteric ischemia. Endovascular stent placement relieved the ischemia with the resolution of pain. Arterial thrombosis should be considered as a diagnostic possibility when patients with CP present with a significant change in symptoms. Importantly, the case demonstrates that endovascular treatment with stent placement can relieve ischemia and resolve symptoms in patients with CP.

Gastric Ulcer Secondary to Left Gastric Artery Thrombosis.

Peptic ulcer disease (PUD) is a well-known and commonly encountered gastrointestinal (GI) pathology. Helicobacter pylori and nonsteroidal anti-inflammatory drug (NSAID) use are the cause of the majority of PUD cases, although other rare etiologies may be encountered. PUD is confirmed by endoscopic visualization of gastric ulcers, with radiographic imaging being less impactful in diagnosis. In this paper, we present a middle-aged patient who presented with PUD caused by thrombotic occlusion of the left gastric artery (LGA), with her diagnosis being made with computed tomography (CT) imaging prior to endoscopy. This case emphasizes the importance of radiographic imaging in the undifferentiated patient, as well as the unique role radiologists play in both discovering diagnoses and their etiologies.

Probiotics and Fecal Transplant: An Intervention in Delaying Chronic Kidney Disease Progression?

Chronic kidney disease (CKD) is a global health challenge affecting nearly 700 million people worldwide. In the United States alone, the Medicare costs for CKD management has reached nearly USD 80 billion per year. While reversing CKD may be possible in the future, current strategies aim to slow its progression. For the most part, current management strategies have focused on employing Renin Angiotensin Aldosterone (RAS) inhibitors and optimizing blood pressure and diabetes mellitus control. Emerging data are showing that a disruption of the gut-kidney axis has a significant impact on delaying CKD progression. Recent investigations have documented promising results in using microbiota-based interventions to better manage CKD. This review will summarize the current evidence and explore future possibilities on the use of probiotics, prebiotics, synbiotics, and fecal microbial transplant to reduce CKD progression.

Fulminant Presentation of Budd-Chiari Syndrome Secondary to COVID-19 Infection.

Budd-Chiari syndrome (BCS) is a rare condition characterized by the obstruction of hepatic venous outflow. It is estimated to affect 1 in 100,000 people worldwide. In cases of new BCS, inherited and acquired hypercoagulability states must be evaluated. Coronavirus disease 2019 (COVID-19) can induce a hypercoagulable state because of its extensive inflammatory response, and while it has been reported to cause portal vein thrombosis, it rarely causes BCS. This article presents a case of a 22-year-old man who developed fulminant symptoms and was subsequently diagnosed with BCS and portal vein thrombosis secondary to COVID-19 infection, after ruling out other inherited and acquired causes of BCS. In addition, a literature review is provided to understand the presentation and management of such patients. Although most patients improve with medical management, this article emphasizes the consideration of liver transplant for patients who do not improve.

Acute Pancreatitis as an Unusual Culprit of Diabetic Ketoacidosis in a Nondiabetic: A Case-Based Review.

Acute pancreatitis has been associated with a multitude of complications including pancreatic necrosis, pseudocysts, abscesses, acute respiratory distress syndrome, disseminated intravascular coagulation, and hyperglycemia. To date, only rare case reports have demonstrated diabetic ketoacidosis (DKA) as a rare sequela of acute pancreatitis. We report a case of a 34-year-old female with no prior history of diabetes who was subsequently diagnosed with DKA after presenting with severe acute pancreatitis. This case serves as a framework to not only highlight DKA as a rare complication of acute pancreatitis but also to explore the potential pathophysiology that underlies this phenomenon including stress hyperglycemia and post-pancreatitis diabetes mellitus.

Common Pathology With Atypical Presentation: Acute Cholangitis.

Acute cholangitis is a well-known biliary tree pathology most often encountered in patients with gallstone disease. When left untreated, acute cholangitis can lead to severe complications, including death. Therefore, identifying and properly treating acute cholangitis is crucial to avoiding such complications. This paper describes an 84-year-old female patient with acute cholangitis who presented with atypical symptoms of chest pain and cough. The patient was successfully treated with endoscopic retrograde cholangiopancreatography (ERCP), antibiotics, and ursodeoxycholic acid. We focus on this patient's unique presentation to highlight the low incidence of Charcot's triad and Reynold's pentad in elderly patients and to emphasize the importance of formulating a broad differential in patients with non-specific symptoms.

Metachronous Squamous Cell Carcinoma of the Esophagus After Resolution of Previous Adenocarcinoma.

Esophageal cancer is the sixth leading cause of cancer-related death worldwide. Metachronous malignancies refer to multiple independent primary cancers diagnosed at least 6 months apart. The incidence of metachronous esophageal cancers with different histologic subtypes is extremely rare. This case presents an unprecedented occurrence of esophageal adenocarcinoma, followed by metachronous squamous cell carcinoma.

Unique Variant of Zieve Syndrome With a Normal Reticulocyte Count.

Zieve syndrome is a rare diagnosis seen in patients with chronic alcohol use which consists of a distinct clinical triad of hyperlipidemia, hemolytic anemia, and jaundice. Patients typically have an elevated reticulocyte count due to the hemolytic nature of the anemia. We present the case of a 44-year-old female who was discovered to have an unusual variant of Zieve syndrome with a normal reticulocyte count, which was believed to be due to suppression of bone marrow from excessive alcohol consumption. She was treated with steroids and complete alcohol cessation, with remarkable improvement on subsequent follow-up. An exhaustive literature review of 31 documented cases of Zieve syndrome was conducted to better understand the clinical presentation and overall prognosis of these patients. This case report and literature review aimed to improve patient outcomes through increased recognition of this underrecognized syndrome.

Severe Gastrointestinal Hemorrhage due to Monkeypox Virus-Associated Proctocolitis.

Monkeypox is primarily a painful cutaneous disease with occasional systemic manifestations. Monkeypox is transmitted predominantly through close physical contact and occasionally sexual contact. The first case was reported in the United States on May 17, 2022, in a recent monkeypox worldwide outbreak. We present a case of severe gastrointestinal bleeding as an atypical manifestation of monkeypox infection in a 40-year-old male with HIV. In our case, monkeypox-induced proctocolitis progressed to severe rectal bleeding requiring one unit of packed red blood cells transfusion despite one week of tecovirimat (TPOXX) therapy. So, patients should be educated about the possibility of unusual complications of monkeypox infection, i.e., bleeding in immunocompromised hosts.

A Rare Case of COVID-19 Vaccination-Induced Cholangiopathic Liver Injury.

Drug-induced liver injury is a serious adverse drug reaction that can result in acute liver injury or cholestatic injury affecting the bile ducts, known as cholangiopathic liver injury (CLI). Although CLI is not as familiar as the hepatocellular pattern, emerging evidence suggests that it may occur after coronavirus disease 2019 (COVID-19) vaccination. This case report focuses on an 89-year-old woman who developed CLI after receiving the tozinameran COVID-19 vaccine. The main aim of this report was to raise awareness of the possibility of developing CLI after COVID-19 vaccination and to underscore the critical significance of promptly identifying and managing this infrequent but severe side effect.

Gastric Outlet Obstruction Caused by Acute Gastric Volvulus: A Rare Complication of Hiatal Hernia.

Hiatal hernias are commonly encountered in elderly patients, predisposing patients to the common condition of gastroesophageal reflux disease (GERD). Depending on the size of the hernia, different complications can arise. Large hernias can lead to development of gastric volvulus, obstruction, strangulation, and perforation. Therefore, management of large hiatal hernias is crucial to avoid such complications. In this paper, we describe a patient who presented with acute gastric volvulus secondary to a large hiatal hernia. She improved with conservative management and subsequently underwent successful repair of the hernia. We emphasized the importance of identifying gastric volvulus among its vague presentation for prompt management.

Rare Presentation of Stercoral Ulcer Spontaneous Perforation Without Preceding Radiographic Evidence of Colonic Inflammation and Fecal Impaction.

Stercoral ulcers are caused by persistent fecal impaction. A life-threatening consequence of stercoral ulcers is colonic perforation, which is rare. A high index of clinical suspicion should be held for patients with stercoral ulcer, as colonic perforation is a medical emergency, requiring immediate surgical intervention. Here, we report a case of a 45-year-old female admitted with sepsis of unknown picture and subsequently developed stercoral ulcer perforation (SUP), diagnosed intraoperatively, without prior radiographic evidence of colonic inflammation. She was successfully managed with emergency laparotomy and left colectomy with sigmoid colectomy.

Role of Plasmapheresis in Hemolysis, Elevated Liver Enzymes and Low Platelets (HELLP) Syndrome.

Hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome is a rare abnormality comprising a series of symptoms that make up a syndrome. It usually happens during pregnancy or right after delivery. We describe a case of a 31-year-old female G4P2A2 (Gravida 4 Para 2 Abortions 2) who presented to the hospital for normal vaginal delivery but immediately postpartum developed HELLP syndrome. Acute fatty liver of pregnancy was a differential that the patient also met the criteria for. Her condition improved after starting her on plasmapheresis without considering hepatic transplantation. We emphasize distinguishing the overlap of symptoms between HELLP syndrome vs. acute fatty liver of pregnancy and the outcomes of plasmapheresis in managing HELLP syndrome without needing hepatic transplantation.

Appendiceal Bulge on Routine Colonoscopy: Not All Disease Is Luminal.

Appendiceal mucocele is an extremely rare pathology accounting for 0.3-0.7% of all appendiceal pathology. It is characterized by appendiceal lumen dilatation by mucinous secretion collection. Though abdominal imaging and tissue Biopsy aids in diagnosis, suspicion should arise when a slight bulge or protrusion is seen on colonoscopy. We present a case of incidental appendiceal bulge found on a routine colonoscopy to evaluate abdominal pain that led to prompt diagnosis and management of appendiceal mucocele.

Methicillin-Resistant Staphylococcus Aureus: A Very Rare Cause of Meningitis.

Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) is mostly implicated in soft tissue and skin infections. Cases with meningitis caused by CA-MRSA are rare. High index of suspicion should be kept for physicians as bacterial meningitis is a medical emergency and if untreated, has a high mortality rate. Urgent steps need to be taken to determine the cause and implement therapy. Here, we reported a case of a 58-year-old female with MRSA bacteremia and meningitis as confirmed by positive blood cultures and cerebrospinal fluid analysis; successfully managed with vancomycin and rifampin.
