Résumé
From October 2015 to August 2018, tapeworm proglottids were obtained from 10 patients who were residents of Daegu and Gyeongbuk provinces and had a history of raw beef consumption. Most of them had no overseas travel experience. The gravid proglottids obtained from the 10 cases had 15–20 lateral uterine branches. A part of internal transcribed spacer 1 (ITS1) DNA of the 10 cases, amplified by polymerase chain reaction (PCR) and digested with AleI restriction enzyme, produced the same band pattern of Taenia saginata, which differentiated from T. asiatica and T. solium. Sequences of ITS1 and cytochrome c oxidase subunit 1 (cox1) showed higher homology to T. saginata than to T. asiatica and T. solium. Collectively, these 10 cases were identified as T. saginata human infections. As taeniasis is one of the important parasitic diseases in humans, it is necessary to maintain hygienic conditions during livestock farming to avoid public health concerns.

pneumonia in the setting of chronic alcoholism and may be complicated by meningitis. Only one adult case of pneumococcal endocarditis (PE) has been reported in Korea. We report the case of a 73-year-old woman who suffered from PE complicated by embolic cerebral infarction and meningitis. This is the first Korean case of PE complicated with meningitis. The patient was treated medically and died from a cardiac complication. This case shows that PE is difficult to treat without surgery because its evolution is usually acute and very aggressive; it has a high rate of local and systemic complications despite the administration of appropriate antibiotics.

Pancreatic intraepithelial neoplasia (PanIN) is a precancerous lesion. A 72-year old man was admitted to our hospital because of abdominal pain, and he had an elevated serum level of pancreatic amylase. ERCP showed a focal stricture of the main pancreatic duct without upstream dilatation in the body of the pancreas. Cytologic evaluation with an endoscopic brush at the stricture suggested the presence of adenocarcinoma. After subtotal pancreatectomy, the features of PanIN were observed in the branch pancreatic duct. ERCP with brush cytology seems to be a useful method for detecting PanIN at the precancerous stage. We report here on a case of PanIN associated with a stricture of the main pancreatic duct.

Calcifying fibrous pseudotumor (CFPT) is very rare and especially at an intrinsic visceral location such as the stomach. The CFPT is generally located in the subcutaneous or deep soft tissue and the subserosal area of organs and it is mainly diagnosed during childhood or young adulthood. The etiology and pathophysiology of CFPT are unclear. Herein we describe a case of gastric CFPT and we review the related literature. A thirty-year-old asymptomatic female patient visited our hospital for the evaluation of a submucosal tumor that was seen on previous endoscopy. On the endoscopic ultrasonography (EUS), a subepithelial lesion was found at the gastric angle and it was a slightly hypoechoic, homogenous mass located at the submucosal layer of the gastric wall. Endoscopic submucosal dissection was performed under the suspicion of carcinoid. On the microscopic findings, most of the tissue was composed of hyalinized collagenous tissue. Mild lymphocytic infiltration and several dystrophic calcifications were also seen. Immunohistochemically, bcl-2 and CD34 staining was negative, so we diagnosed the mass as CFPT.

Lymphoepithelial cyst is a rare benign cystic tumor that is composed of a squamous epithelial cyst surrounded by lymphoid tissue, and this type of cyst is histologically similar to the branchial cleft cysts of the lateral neck. It is most often found in the head and neck and it is only rarely found in the pancreas, mediastinum and hypopharynx. Lymphoepithelial cysts of the esophagus have been described in Japan by Kataoka and Asami. We report here on a case of esophageal lymphoepithelial cyst that was removed endoscopically without serious complications.
