A pyogenic liver abscess secondary to appendicitis infection is a rare manifestation that has not been well illustrated in the United States due to its infrequency and the variability of each clinical presentation. Here, we discuss a 55-year-old male who presented with abdominal pain, fever, chills, and weight loss and was found to have a pyogenic liver abscess suspected secondary to radiographic-proven acute appendicitis. The purpose of this article is to describe a patient who presented with noteworthy clinical features and a rare cause of hepatic abscess, to aid in the treatment and diagnosis of future patients.

BackgroundColorectal cancer is the third leading cause of cancer death; therefore early detection by screening is beneficial. Residents at a clinic in NJ, USA were not offering other forms of colon cancer screening when patients refused colonoscopy, which lead to the creation of the quality improvement project.MethodsResidents practicing at the clinic were given an anonymous survey determining which method of colon cancer screening they used and which alternative method they offered when patients refused the original method. The residents were educated about all methods of colon cancer screening and the residents were resurveyed.ResultsA total of 64% of residents offered less invasive testing when colonoscopy was refused. Six months after education, 95% of residents offered less invasive testing when colonoscopy was refused.ConclusionsEarly detection and removal of polyps by colonoscopy reduce the risk of cancer development. Colonoscopy is the gold standard for colon cancer screening; however other less invasive modalities are approved. This quality improvement project lead to offering the fecal immunochemical test or fecal occult blood test once patients refused colonoscopy at the clinic, increasing the number of patients receiving colorectal cancer screening, and thus providing better medical care.

Mixed adenoneuroendocrine carcinoma (MANEC) of the gastrointestinal (GI) tract is a rare subtype of mixed tumors, and it is scarcely described in the literature. MANEC tumors are composed of adenocarcinoma and neuroendocrine carcinoma components, each of which comprises at least 30% of the lesion. Diagnosing MANEC requires specific histological and immunohistochemistry (IHC) analysis. Typically, MANEC tumors carry a poor prognosis due to their very aggressive nature.We report the case of a 70-year-old female patient with no past medical history who presented with a threeweek history of abdominal pain and one episode of hematemesis one week prior to presentation. Initial CT of the abdomen showed a large, 8 x 6 x 6-cm mass arising from the stomach and extending to the lesser sac as well as the central crus of the diaphragm with bilateral retroperitoneal lymphadenopathy. Upper endoscopy revealed an excavated, ulcerated, and partially necrotic mass on the lesser curvature of the proximal gastric body. Tissue biopsy of the lesion showed infiltrating mixed poorly differentiated adenocarcinoma and neuroendocrine carcinoma. On IHC, the adenocarcinoma component stained positively for CDX2 and pancytokeratin, and the neuroendocrine component stained positively for synaptophysin and chromogranin. Further workup included CT of the chest, which demonstrated extensive bilateral pulmonary emboli and new liver lesions with moderate ascites not seen on the initial abdominal CT. The latter was repeated and showed remarkable enlargement of the gastric mass (up to 12 cm) with extensive retroperitoneal adenopathy and mesenteric implants. Given the rapid clinical deterioration and progression of tumor burden, comfort measures were offered and the patient passed away soon after. MANEC tumors are highly aggressive subtypes of "collision" tumors, which are not well described in the medical literature due to their rarity. The etiology is poorly understood with various theories proposing different pathophysiological mechanisms. Standard therapy is not well developed at present; however, a few reports have demonstrated successful outcomes with surgery or combined chemotherapy (cisplatin with irinotecan or etoposide) if diagnosed at an early stage.

Hemosuccus pancreaticus (HP) is defined as bleeding from the ampulla of Vater through the pancreatic duct. It is a rare complication associated with acute or chronic pancreatitis. The source of bleeding can be from the pancreas itself or surrounding vessels, with the splenic artery most commonly involved. Diagnosing HP is challenging and computed tomography angiography remains the gold standard for diagnosis. We present the case of a 62-year-old male with recurrent pancreatitis complicated with HP. Imaging and endoscopy were consistent with bleeding from the section portion of the duodenum, which resolved without intervention.
