A Case of Low-grade Fibromyxoid Sarcoma of the Colon / 대한소화기학회지

Low-grade fibromyxoid sarcoma is a slowly growing soft tissue neoplasm that shows benign histologic features but may have clinical course of malignant disease. It has been reported to occur in the thigh, inguinal area, axilla, shoulder, neck, perineum or buttock. However, there have been few cases of abdominal organ involvement. A 21-year-old woman presented with a large palpable abdominal mass. A 7x4 cm sized round soft tissue tumor at right upper quadrant area was identified by abdominopelvic CT scan. Percutaneous ultrasound-guided biopsy revealed features of spindle cell tumor. On exploration, the tumor originated from transvers colon and was attached to gastrocolic ligament, transverse mesocolon and stomach. The tumor could be dissected with transverse colectomy and partial gastrectomy. The excised tumor, measuring 7x5x5 cm, was well demarcated and appeared as an ovoid mass with firm and myxoid cut surface. She was diagnosed with low-grade fibromyxoid sarcoma arising from transverse colon, and is currently being followed-up without recurrence or metastasis.

A Case of Acute Recurrent Pancreatitis Caused by Metastasis of Renal Cell Carcinoma to the Ampulla of Vater / 대한내과학회지

Metastasis of renal cell carcinoma to the ampulla of Vater is a rare occurrence. We report a case of acute recurrent pancreatitis caused by metastasis of renal cell carcinoma to the ampulla of Vater. The patient manifested acute recurrent pancreatitis 10 years after a nephrectomy for renal cell carcinoma and was presumed to have obstructive pancreatitis secondary to an ampullary mass. Duodenoscopy revealed an ampullary mass, and the patient was finally diagnosed with metastatic renal cell carcinoma. With insertion of a pancreatic stent via endoscopic retrograde cholangiopancreatography, the acute pancreatitis was resolved. When an ampullary mass is observed in a patient with a history of renal cell carcinoma, the possibility of ampullary metastasis of the renal cell carcinoma should be considered, as this is a potential etiology of acute recurrent pancreatitis.

A Case of Rifampin-Induced Recurrent Adrenal Insufficiency During the Treatment of Pulmonary Tuberculosis in a Patient with Addison's Disease / 영남의대학술지

Adrenal insufficiency during the treatment of pulmonary tuberculosis is a troublesome condition and can at times be lifethreatening if untreated. Rifampin is one of the most widely prescribed anti-tuberculosis agents. Furthermore, rifampin has been known to be capable of affecting the metabolism of various medications, including glucocorticoids. In this paper, a case of recurrent adrenal insufficiency induced by rifampin during the treatment of pulmonary tuberculosis is reported. The patient was a 63-year-old man who was diagnosed with Addison's disease 17 years earlier and had been undergoing glucocorticoid replacement therapy. Five months before, the patient manifested pulmonary tuberculosis and was immediately given anti-tuberculosis medication that included rifampin. After one week of medication, general weakness and hyponatremia occurred. Despite the increased dose of the glucocorticoid medication, the adrenal insufficiency recurred many times. Since the substitution of levofloxacin for rifampin, the episodes of adrenal insufficiency have not recurred so far.

A Case Report of Methimazole-Induced Acute Liver Failure Successfully Treated with Liver Transplantation / 대한내과학회지

Antithyroid drugs inhibit the synthesis and excretion of thyroid hormone from the thyroid gland. Propylthiouracil (PTU) and methimazole are well known as antithyroid drugs. In 2011, the American Thyroid Association and American Association of Clinical Endocrinologists published management guidelines for hyperthyroidism and other causes of thyrotoxicosis, and recommended methimazole as the first-choice antithyroid drug for the treatment of hyperthyroidism. Lower hepatotoxicity is an advantage of methimazole. Fulminant hepatitis rarely occurs in methimazole users, and spontaneous recovery is expected even if it does occur. We describe a rare case of acute liver failure after methimazole intake in a 60-year-old man who underwent liver transplantation.

A Case of Severe Pneumonia with Rhabdomyolysis Caused by Mycoplasma Pneumonia / 대한내과학회지

Mycoplasma pneumoniae is a common cause of respiratory tract infections and typically causes mild disease. Extrapulmonary manifestations of M. pneumoniae infection are also common, but rhabdomyolysis is a rare complication. Here, we describe the case of a previously healthy 23-year-old male who displayed the simultaneous onset of rhabdomyolysis and severe pneumonia requiring mechanical ventilation. Both conditions were resolved by a 10-day course of antimicrobial treatment and the patient was discharged without complication.

The Primary Biliary Cirrhosis Presenting with Raynaud's Disease and Digital Necrosis

Necrosis of the upper extremity occurs rarely in type 2 diabetic patients compared to lower extremity necrosis. We report a 69-year-old woman with type 2 diabetes mellitus who presented with necrosis of the left 5th finger tip. The patient had primary biliary cirrhosis accompanied by necrosis of the fingertip due to severe Raynaud's phenomenon. Primary biliary cirrhosis (PBC) is a typical autoimmune disease, which can in rare cases be accompanied by autoimmune symptoms including sicca symptom and Raynaud's phenomenon. Furthermore, autoimmune diseases, such as systemic sclerosis, rheumatoid arthritis and undifferentiated connective tissue disease (UCTD) can be associated. Although every type of vascular etiology should be considered as a cause of digital necrosis, Raynaud's phenomenon is usually not considered in diabetes. We report this case of finger tip necrosis due to severe Raynaud's phenomenon accompanied by PBC and UCTD in a diabetic patient.

A Case of Marfan Syndrome with Subacute Bacterial Endocarditis

Marfan syndrome is a hereditary disorder of connective tissue fibers, involving skeleton, eye and cardiovascular system. The cardiovascular complications, directly related to the cause of death, are associated with about 90% of the Marfan syndrome. The cardiovascular complications are aortic and mitral insufficiency, mitral valvular prolapse, bacterial endocarditis, arrhythmia and aneurysm of interatrial septum and aorta. Among the cardiovascular complications, bacterial endocarditis is unusual. The aortic valve, though commonly abonormal in Marfan syndrome, was rarely involved by endocarditis. In contrast the mitral valve was the favoured site of infection in these patients. The low incidence of aortic valve involvement remains unexplained. There is extreme mortality in Marfan patients affected by endocarditis. A 22-year-old man was admitted to Wallace Memorial Baptist Hospital because of intermittent fever with chill, dyspnea and orthopnea. He had characteristic Marfanoid features such as a slender body with sparsity of subcutaneous fat, arachnodactly and disproprtionate long extremities, axial myopia as well as suspicious family history. Three blood cultures produced a slowly growing gamma-hemolytic streptococcus sensitive to penicillin. Chest X-ray revealed increased C-T ratio and generalized congested lung parenchyme and increased lung markings with multiple dense, horizontal lines, so called Kerley's B lines. Echocardiogram showed thickened bicuspid arotic valve with vegetation and enlarged left ventricular cavity, grade 3/4 mitral and aortic regurgitation. The authors have experienced a rare case of Marfan syndrome with subacute infective endocarditis.

A Case of Peutz - Jeghers syndrome Accompanied with Intussusception / 대한소화기내시경학회지

The Peutz-Jeghers syndrome is a familial disesse charaeterized by mucocutaneaus pigmentation, gastrointestinal polyposis, and transmission of autosomal dominant trait. This syndrome is clinically important becuase of the coreplieation caused by the polyp, leading to abdominal pain, gastrointestinal bleeding, and intussusception. Authors experienced a case of Peutz-Jeghers syndrome admitted to Walace Memorial Baptist Hospital who was complained of recurrent abdominal pain, melanin pigmentation of lips, oral mucosa, and digits. UGI series, small bowel series, colon cnema, gastrofiberscopy, and colonoseopy revealed multiyle intestinal polyps. Pathologic findings on endoseopic polypectomy showed hamartomatous polyp.

Clinical Observation of Acute Myocardial Infarction

A Clinical study was done on 90 cases of acute myocardial infarction admitted to Busan Wallace Memorial Baptist Hospital from January, 1977 to Febuary, 1983. The following results have been obtained. 1) The ratio of male to female was 2.2:1. The most age group were 5th decades(35.6%) and over 5th decades(5th decades and 6th decades) were two-thirds of all age group. And annual incidency were increasing tendencies, in 1980-1982 than 1977-1979. 2) Between the preceding diseases and the risk factors, the most common cause was the smoking (60%). And other associated diseases and factors were hypertension(54.4%), hypercholesterolemia (43.8%), hyperlipidemia(51.4%) and angina pectoris (34.4%). 3) The most common inducing factor was physical exertion(33.3%). And others were emotional stress(23.3%), alcohol drinking(10%), rest and sleeping(5.6%). 4) The major symptoms of acute myocardial infarction were precordial or epigastric pain(96.7%), dyspnea(53.3%), radiating chest pain (51.7%) and painless infarction(3.3%). 5) On laboratory data, there were leukocytosis in 50.5% increased SGOT in 68.6%, increased serum LDH in 75.9% and cardiomegaly in chest x-ray film were 82 percents. 6) The ratio between the anterior and inferior infarction on EKG was 1.9:1. 7) When admission, normal sinus rhythms on EKG were 59 percents. And the common associated electrocardiographic abnormalities were ventricular premature beat (23.6%), atrial fibrillation(15.7%), first degree A-V block (15.7%), left ventricular hypertrophy(15.7%). The most common abnormality was ventricular premature beat(23.6%). 8) The mortality rate of acute myocardial infarction was 10 percents. The causes of death were heart failure(33.3%), ventricular arrhythmia(33.3%), sudden death (22.2%) and cardiogenic shock(11.1%).
