A case of juxtapapillary gangliocytic paraganglioma treated with endoscopic resection / 대한내과학회지

Gangliocytic paraganglioma is a rare tumor that is usually seen in the duodenum. This neoplasm generally behaves in a benign fashion, although instances of recurrence and lymph node metastasis have been described. We experienced a case of incidentally found gangliocytic paraganglioma treated with endoscopic resection. A 61-year-old man was referred because of submucosal tumor adjacent to the major papilla. Endoscopic biopsy revealed paraganglioma. Abdominal CT showed that there was no evidence of a duodenal mass or lymphadenopathy. This tumor was resected endoscopically by electrosurgical snare polypectomy. The excised tumor measured 1.0 cm in diameter. Histopathological examination revealed a benign gangliocytic paraganglioma and the resection margins were free of tumor. At the 6-month follow-up, the patient was still asymptomatic and no residual tumor was detected at the resection site.

A case of anaphylaxis to erythromycin / 대한내과학회지

Macrolides antibiotics synthesized by Streptomyces strains are prescribed widely and seldom produce hypersensitivity reactions, even when administered topically. Consequently, they are considered very safe drugs. We report the case of a 32.year.old woman who developed anaphylactic shock after ingesting erythromycin, which she had taken twice before. The previous exposure to erythromycin, clinical findings, and a positive skin intradermal test with erythromycin (10 mg/mL) support the postulate that anaphylaxis was induced by erythromycin.

Hypertriglyceridemia-induced acute pancreatitis in pregnancy: A case report / 대한내과학회지

Hypertriglyceridemia-induced pancreatitis is a rare, but serious, complication of pregnancy. We report a case of acute pancreatitis associated with type V hyperlipoproteinemia in pregnancy. A 36-year-old primigravida was admitted at 16 weeks of gestation with severe abdominal pain. Chemical analysis showed high serum pancreatic enzymes and very high serum triglyceride. Abdominal magnetic resonance imaging (MRI) showed diffuse swelling of the pancreas and a peripancreatic fluid collection. A diagnosis of acute pancreatitis with type V hyperlipoproteinemia was made. She recovered from the acute pancreatitis with conservative management and the serum triglyceride decreased rapidly with dietary restriction of fat, insulin/glucose, fenofibrate, and omega-3. We review the management of hypertriglyceridemia-induced acute pancreatitis in pregnancy.

A Case of Congenital Hepatic Fibrosis Presented with Recurrent Acute Cholangitis / 대한소화기학회지

Acute cholangitis usually develops in congenital hepatic fibrosis (CHF), accompanied by cystic dilated bile ducts. However, it can also develop in simple CHF and may lead to critical course. A 30-year old man presented with recurrent acute cholangitis without bile duct dilatation. He visited the hospital for febrile sense and abdominal pain in the right upper quadrant. He had been admitted several times for hepatosplenomegaly and cholangitis since childhood and received a liver biopsy 15 years ago. Abdominal computed tomography (CT) and endoscopic retrograde cholangiopancreatography (ERCP) revealed hepatosplenomegaly and a mildly dilated bile duct without stones or biliary cysts. His condition improved after conservative treatment. However, during a two-month follow up period, the patient experienced three episodes of acute cholangitis. A liver biopsy was performed and showed periportal fibrosis and intrahepatic ductular dysplasia, characteristics of congenital hepatic fibrosis. The periportal fibrosis and the infiltration of inflammatory cells were aggravated compared to 15 years ago. There was no evidence of hepatic cirrhosis. He was diagnosed with congenital hepatic fibrosis with recurrent acute cholangitis without intrahepatic duct dilatation, and conservatively treated with antibiotics.

Two Cases of Acyclovir Neurotoxicity in End Stage of Renal Disease / 대한신장학회지

Acyclovir is an anti-viral nucleoside analogue that was discovered in 1972. Since it was put to use in clinical practice, some adverse events had been reported. Renal dysfunction and disturbance of central nervous system are the two major adverse effects. A 60-year-old man who was being treated with peritoneal dialysis was admitted for sudden onset of sensory-neural hearing loss. A 67-year-old man who was being treated with hemodialysis was also admitted for Bell's palsy. After two days of treatment with intravenous acyclovir and oral prednisolone, they had hallucinations, myoclonus, disoriented mentality and agitation. Furthermore, the latter had stupor. We did some laboratory examination, brain MRI and electroencephalography (EEG), but there was no cause for neurologic abnormality. In the clinical suspicion of acyclovir neurotoxicity, we discontinued acyclovir and went on dialysis therapy. They fully recovered after several days. Our cases further reinforces the claim that the dose of acyclovir should be reduced in patients with renal failure and dialysis is a good form of treatment for overdosage.

Intra-abdominal Kikuchi's Disease Mimicking Malignant Lymphoma on FDG PET-CT / 핵의학분자영상

Kikuchi's disease is a self-limiting benign disease characterized by cervical lymphadenopathy, but it can be mistaken for malignant disease, and when involved lymph nodes are unusually located, diagnosis can be more difficult. The authors report the case of a 19-year-old man with Kikuchi's disease, who had isolated intraabdominal lymphadenopathy and increased 18-fluoro-deoxyglucose (FDG) uptake in positron emission tomographycomputed tomography (PET-CT). Although its incidence is extremely rare, intra-abdominal Kikuchi's disease with increased FDG uptake in PET-CT image should be considered in the differential diagnosis when constitutional symptoms mimic those of malignant lymphoma.
