Promising therapies for the future treatment of AA are JAK-STAT inhibitors and PRP.We describe a case of a mucosal prolapse syndrome (MPS)-like inflammatory polyp protruding from the appendiceal orifice, mimicking an appendiceal neoplasm. A 48-year-old man presented with lower abdominal pain and elevated white blood cell count and C-reactive protein level. Computed tomography showed a swollen appendix with multiple small saccular lesions and periappendiceal fat stranding and small saccular lesions in the ascending colon and cecum. Ultrasonography showed a swollen appendix 25 mm in diameter with multiple saccular structures and a periappendiceal high-echoic area, suggesting appendiceal diverticulitis. Colonoscopy revealed an erythematous lesion protruding from the appendiceal orifice. An ileocecal resection was performed based on a preoperative diagnosis of appendiceal diverticulitis and tumor. Histopathological examination of the appendix showed multiple mucosal herniations with infiltration of inflammatory cells, indicating appendiceal diverticulitis. The tumor was characterized by glandular duct hyperplasia and stromal expansion with smooth muscle hyperplasia and was diagnosed as an inflammatory polyp resembling an MPS lesion. Although several studies have shown the macroscopic and endoscopic appearance of MPS-like inflammatory lesions associated with colonic diverticular disease, this case was the first to present an inflammatory polyp associated with appendiceal diverticulitis in which the lesion protruding from the appendiceal orifice was masquerading as an appendiceal neoplasm.We present a case of eosinophilic esophagitis (EoE) with positive skin-prick testing for type I allergy to red yeast rice (RYR, Artechol®). RYR is an over-the-counter supplement for hypercholesterolemia, since years famous in Asian countries and now also more and more popular in Western countries. The clinical relevance of IgE-mediated inflammation was proven by a rapid clearance of EoE-symptoms upon discontinuation of RYR. The role of skin-prick testing and allergy testing in general in EoE is controversial, but was of high importance in our patient. It demonstrates that in cases of a clear-cut allergy history, together with positive skin-prick (IgE) testing, a broad elimination diet can thus be avoided.Gallbladder cancer is often diagnosed with metastasis and is known to have poor prognosis. Although, gallbladder cancer often metastasizes to liver, lung, or lymph nodes, metastasis to gastrointestinal tract is not common. Several autopsy studies reported colorectal metastasis from gallbladder cancer, but most of these cases were supposed to be gastrointestinal invasion from peritoneal dissemination. We experienced a rare case of hematogenous colon metastasis from gallbladder cancer. Colonoscopy for a 76-year-old man who was diagnosed as gallbladder cancer revealed two 5-mm flatly elevated lesions with central erosion in the transverse and sigmoid colon.

Additional immunohistochemistry examination showed strongly positive CK7 expression with negative CDX2, and suggested colon metastases from gallbladder cancer. Despite the positive vertical margin in EMR specimens, autopsy finding denied colorectal invasion from peritoneal dissemination and proved vascular spread colon metastases. Gastrointestinal metastasis is often misdiagnosed as a primary tumor, and thus, it is important to recognize gallbladder cancer as a potential origin of gastrointestinal metastasis.A 78-year-old man with a subepithelial lesion (SEL) in the gastric body and two carcinomas in the gastric antrum was referred to our hospital. Following a diagnosis of SEL, the patient was followed-up by esophagogastroduodenoscopy annually for 4 years. Although the SEL had increased in size over the years, histological evaluation of the forceps biopsies did not reveal any significant findings. We detected a hypoechoic mass in the submucosa by endoscopic ultrasonography, and suspected the lesion to be an aberrant pancreas or mesenchymal tumor. The patient first underwent endoscopic submucosal dissection for the 2 gastric cancers. Histological examination of the resected specimens revealed intramucosal well-differentiated tubular adenocarcinomas. Next, endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) was performed for the gastric SEL. Aspirated specimens revealed an adenocarcinoma with lymphocyte infiltration. The lesion was diagnosed as a gastric carcinoma with lymphoid stroma (GCLS). Subsequently, he underwent distal gastrectomy, and the surgical specimen was confirmed as GCLS corresponding to preoperative diagnosis. In addition, the adenocarcinoma cells were positive for Epstein-Barr (EB) virus-encoded small RNA-1 by in situ hybridization. Finally, the lesion was diagnosed as GCLS associated with EB virus. Thus, EUS-FNA is advantageous for diagnosing GCLS associated with EB virus.Antiphospholipid syndrome (APS) is a systemic autoimmune disorder characterized by arterial and/ or venous thrombosis accompanied by persistently elevated levels of antiphospholipid antibodies (aPLs). The aim of this study is to evaluate the pulmonary manifestations of APS and compare the levels of aPLs in patients with and without pulmonary involvement. We retrospectively reviewed the files of patients with the diagnosis of APS between October 2010 and May 2017. Demographic data, clinical, radiological and laboratory findings were recorded. The study included 67 patients (56 female/11 male) with a mean age of 39 ± 13 years. Pulmonary manifestations such as parenchymal and/or vascular involvement were seen in 12 (17.9%) patients. The patients with and without pulmonary manifestations were not significantly different in terms of age (p = 0.46), comorbidities (p = 0.48) and APS duration (p = 0.66). Acute pulmonary thromboembolism (PE) was determined in 11 (16.4%), alveolar hemorrhage in 2 (3%) patients. Four patients with acute PE (36%) developed chronic thromboembolic pulmonary hypertension (CTEPH). One patient developed both CTEPH and diffuse alveolar hemorrhage after acute PE during follow up. Antiphosholipid antibody IgM was highly positive in patients with PE compared to patients without PE (p = 0.005). Other antibodies and lupus anticoagulant were not significantly different in patients with and without PE. None of the patients were deceased due to pulmonary manifestations of APS. PE was the most common pulmonary manifestation of APS. The development of CTEPH was high among APS patients. Patients with APS should be closely followed for the onset of PE and CTEPH.
