A case of ischemic colitis in ascending colon mimicking colon cancer / 대한내과학회지

Ischemic colitis is recognized as the most common vascular disorder of the intestines in the elderly. Correct diagnosis is usually made after the ischemic episide is over and ischemic colitis is frequently misdiagnosed. A case is presented in which an initial diagnosis of appendicitis was made. On operation, a tumor like mass was found in ascending colon. Pathological examination revealed ischemic colitis. We report a case of ischemic colitis in ascending colon mimicking colon cancer.

A Case of Rifampicin Induced Pseudomembranous Colitis in Elderly Patient

Nowadays, the increasing use of antibiotics induces many complications including pseudomembranous colitis. Isolates of toxigenic Clostridium difficile, the most frequent cause of antibiotic-associated pseudomembranous colitis, are almost always highly susceptible to rifampicin. However, resistant isolates exist and have been associated with colitis in humans. We report a case of pseudomem- branous colitis associated with rifampicin administration.

An elderly patient with gastric adenocarcinoma developing multiple metastasis in skeletal muscle / 대한내과학회지

Gastric cancer occurs with high frequency and is a significant cause of cancer motality in Korea. The most common metastatic sites of gastric cancer are liver, lung, bone and adrenal gland. Intramuscular metastasis from gastric cancer is an rare case. Skeletal muscle is one of the most unusual sites of metastasis from any malignancy. We report an elderly patient with gastric cancer developing multiple metastasis in skeletal musle.

A case of cervical lymphadenitis by toxoplasmosis / 대한내과학회지

Toxoplasma lymphadenitis is the most common clinical manifestation of toxoplasmosis in an immunocompetent host. The cervical lymph nodes are the most commonly involved, whereas systemic manifestations are rare. The most common clinical presentations are asymptomatic or subclinical, with fever, maculopapular rash, and general malaise. In immunocompromised patients, the presentations may be devastating with disseminated disease resulting in encephalitis, myocarditis, and pneumonia. We are reporting a case of toxoplasma lymphadenitis in an immunocompetent host diagnosed by histologic and serologic evaluation.

A Case of Polymyos itis Associated with Liver Cirrhosis

Polymyositis is uncommon connective tissue disease of autoimmune etiology in which the skeletal muscle is damaged by a inflammatory process dominated by lymphocytic infiltration. Polymyositis has been associated with several viral infections, and a spectrum of immune-related diseases may occur with hepatitis C virus(HCV) infection. However, no association between polymyositis and HCV infection has been reported previously. We report a case of polymyositis combined with liver cirrhosis who had evidence of HCV infection.
