High Grade Myxofibrosarcoma in the Paravertebral Muscle: A Case Report
남동혁,김태완,박관호,김재오 대한척추신경외과학회 2010 Neurospine Vol.7 No.4
Many different abnormalities, such as, neoplasm, infection, traumatic hematoma, or congenital or immune myopathy, may be found in the paravertebral muscles. However, neoplasms of paravertebral muscle are an uncommon cause of back pain. Such neoplasms may arise from local lesions or due to metastatic spread from a distant malignancy. The differential diag- noses of a primary soft tissue malignancy and metastatic spread from a skeletal muscle tumor are important. In cases of soft tissue sarcoma, histopathological findings and surgical margins are both related to local recurrence and metastasis, therefore, percutaneous needle biopsy may be helpful before surgical excision. A degree of surgical excision is decided based on considerations of muscular function and histopathological findings.

Tuberous sclerosis (TS) is an autosomal dominant disorder that is characterized by cutaneous lesions, seizures, mental retardation and hamartomas in various organs including the skin, kidney and brain. Pulmonary involvement is extremely rare, and occurs in approximately 0.1 to 1% of TS cases. Recent reports have indicated multiple micronodular pneumocyte hyperplasia (MMPH) as another rare form of pulmonary involvement of tuberous sclerosis. We report a case of a 35 year-old-male patient who had no pulmonary symptoms but showed multinodular pulmonary shadows on his chest CT scan. The patient was finally diagnosed with TS with MMPH of the lung. MMPH does not appear to have any malignant potential but the clinical significance of MMPH in TS patients is unknown.

Polyarteritis nodosa (PAN) is a rare systemic necrotizing vasculitis involving multiple organ system. Systemic lupus erythematousus (SLE) also presented as a vasculitic symptoms. So, systemic vasculitis and SLE share some clinical features. We report a case of polyarteritis nodosa mimicking SLE. A 45-year-old woman was admitted due to oliguria. She diagnosed SLE because of pericardial effusion, hemolytic anemia, proteinuria, hematuria, and positivity of anti-dsDNA antibody. But she re-diagnosed as PAN through renal angiography and renal biopsy afterwards. She was treated with high dose steroid, cyclophosphamide, and anti-TNF-alpha antibody, but didn't respond those therapies.

Alcaligenes xylosoxidans is a catalase and oxidase positive, motile, nonfermentative and gram-negative rod bacterium. A. xylosoxidans infection is a rare cause of pulmonary infection and little information concerning treatment is available. The majority of patients that develop A. xylosoxidans infection belong to a high-risk group due to an immunocompromised condition or due to pulmonary cystic fibrosis. We report two rare cases of immunocompentent patients that developed a pulmonary infection due to A. xylosoxidans. A 77-year-old man was admitted with a lung abscess. The patient denied having any prior medical illness. A culture of bronchial washing fluid showed the presence of A. xylosoxidans. Despite appropriate antibiotic treatment, the patient died from acute respiratory distress syndrome (ARDS). Another patient, a 61-year-old man without an underlying disease, was admitted with empyema. Under the condition of a closed thoracostomy, a high fever persisted and the empyema was also aggravated. A. xylosoxidans was detected from a culture of pleural fluid. Susceptible antibiotic treatment was provided and surgical intervention was performed. We report these cases with a review of the literature. (Tuberc Respir Dis 2008;64:33-38)
소장에서 직장까지 침범한 광범위 Lupus Enteritis 1예
김도현,나형중,최유리,남동혁,이찬희,박수미,강원석 대한류마티스학회 2007 대한류마티스학회지 Vol.14 No.3
Systemic lupus erythematosus (SLE) is a multisystem ic inflammatory disorder mediated by autoantibodies and immune complexes that manifests with a variety of symptoms. Lupus enteritis is a serious complication of SLE and carries a high mortality rate, however the diagnosis is not easy for there are no specific clinical manifestations and laboratory findings. Lupus enteritis usually involves the mesenteric arteries causing ischemic changes of the small and large bowels, and yet rarely involves the rectum. Here, we report a case of a 26-year-old female lupus enteritis patient who presented with atypical abdominal pain. Early diagnosis was made by abdominal pelvic computed tomography (CT) scan, which showed extensive involvement of lupus enteritis from proximal small bowel to rectum. She recovered after being treated with high dose steroid therapy.
Lethal Aspergillus Endocarditis After Heart Transplantation
박은영,강석민,김찬호,김동현,남동혁,안철민,정보영,정남식 한국심초음파학회 2007 Journal of Cardiovascular Imaging (J Cardiovasc Im Vol.15 No.2
We report a case of a 21-year-old male who died from lethal Aspergillus endocarditis 3 months after heart transplantation. He underwent heart transplantation in other country. He was treated with hemodialysis for acute renal failure due to cyclosporine and then transferred to our hospital. When he complained high fever, follow-up echocardiography showed a large mobile echogenic mass attached to posterior mitral valve leaflet. The result of serum Aspergillus galactomannan antigen assay was positive. He was empirically treated with intravenous amphotericin B and antibiotics. However, he was rapidly deteriorated and died on hospital day 3.

In the average adult with a normal immune state, Epstein-Barr virus pneumonia is very rare, especially in the form of interstitial lung disease. According to recent studies, the Epstein-Barr virus is also associated with lymphocytic interstitial pneumonia, AIDS and Langerhans cell histiocytosis, but not with sarcoidosis. BOOP is caused by lung injury due to an infection or drug intoxication, and is related to connective tissue disease or bone marrow transplantation, but is sometimes idiopathic. We experienced a patient with symptoms and signs of interstitial lung disease, with confirmed BOOP and EBV ingection from an open lung biopsy and serologic examination, respectively Herein, this case is reported, with a review of the literature.
