Mucinous gastric carcinoma (MGC) is an unusual histologic subtype, and early detection of MGC is very rare. Early stage MGC appears as an elevated lesion resembling a submucosal tumor (SMT) due to abundant mucin pools in the submucosa or mucosa. We report a rare case of SMT-like early-stage MGC. Tumor type was predicted preoperatively based on characteristic endoscopic findings, in which an SMT-like mass was observed at the gastric fundus. The tumor was covered by nearly normal mucosa, but with an opening allowing for the passage of copious mucus discharge. A total gastrectomy with Roux-en Y esophagojejunostomy was subsequently performed. Histopathology of the tumor revealed early-stage (lamina propria) mucinous adenocarcinoma.

Standard antituberculous therapy, including isoniazid (INH), rifampin, ethambutol, and pyrazinamide (PZA), is widely used to treat active tuberculosis. The most important side effect is hepatotoxicity. In a standard four-drug regimen, PZA was the most common cause of drug-induced hepatitis and was dose-related. The incidence of drug-induced hepatitis is high at doses of 40∼70 mg/kg per day but has fallen significantly since the recommended dose was reduced. Liver toxicity induced by PZA is rare at doses of 25 mg/kg per day or less. PZA-induced fulminant hepatic failure is also rare but fatal. We report a case of fulminant hepatic failure caused by a re-challenge of PZA. (Tuberc Respir Dis 2007;63:435-439)

저자들은 65세 남자 환자의 위 중부체부 대만부 전벽에 발생한 점막하 종양에 대하여 3년간 추적관찰 중 크기증가소견으로 쐐기 절재술을 시행하였으며, 조직검사 및 면역 조직 화학 검사에서 위 신경초종으로 진단한 1예를 경험하였기에 보고하는 바이다. Gastric schwannoma is a very rare gastrointestinal benign tumor, which represents only 0.2% of all gastric tumors and 4% of all benign gastric tumors. We report a case of gastric schwannoma with enlargement of size through serial endoscopic examination. Endoscopic examination showed a hard mass of 4 x 3 cm in size with normal overlying gastric mucosa on the great curvature of the mid-body of stomach. The pathological finding revealed a picture of spindle cell tumor. Immunohistochemical stain was strongly positive for S-100 protein and non-reactive for CD34, C-kit and smooth muscle actin, thus leading to the diagnosis of gastric schwannoma.

28세 남자가 내시경적 점막절제술을 통해 저등급 위MALT 림프종으로 진단되었다. 병기설정을 위해 18F-FDG PET 검사를 시행하였고 우측 쇄골상부, 우측상/하부 기관주위, AP window 부위에 강한 섭취가 관찰되어 전이성 림프절로 판단하였다. 그러나, 우측 쇄골상부 림프절에서 시행한 절제생검에서 만성육아종성염증소견이 관찰되었고 조직의 결핵 중합효소연쇄반응에서도 양성 반응을 보였다. 2개월간 항결핵제의 사용 후 시행한 추적 컴퓨터단층촬영 검사에서 림프절 크기의 감소를 보여 최종적으로 위 MALT 림프종에서 광범위 림프절 전이로 오인된 동시성 림프절 결핵으로 진단되었다. A 28-year-old man was diagnosed as gastric MALT lymphoma in diagnostic EMR (endoscopic mucosal resection). He subsequently underwent an 18F-FDG PET. 18F-FDG PET showed intense multifocal uptake in right supraclavicular, right upper and lower paratracheal, and AP window areas that was considered radiologically to represent widespread metastatic lymphadenopathy. Excisional biopsy of a supraclavicular lymph node, however, revealed chronic granulomatous lymphadenitis with a positive reaction of Tb-nested PCR. After antituberculosis treatment for 2 months, a follow-up CT scan showed complete resolution of the lesions. Intense 18F-FDG uptake could be due to an infectious process such as synchronous tuberculous lymphadenitis. Therefore, this could mimic a malignant condition such as lymphoma with extensive lymph node metastasis due to a false-positive finding, which may lead to a misdiagnosis.
