Résumé
BACKGROUND/AIMS: Neuroendocrine tumors (NETs) may originate from heterogeneous neuroendocrine cells. The incidence is increasing worldwide, and World Health Organization (WHO) updated its classification in 2010. We investigated clinical characteristics of gastroenteropancreatic NETs in a single center. METHODS: Clinicopathologic characteristics of patients with pathologically confirmed gastroenteropancreatic NET in Seoul St. Mary Hospital from March 2009 to August 2011 were retrospectively analyzed. The grade and stage were determined according to WHO 2010 classification and TNM Staging System for Neuroendocrine Tumors (7th ed., 2010) of American Joint Committee on Cancer. RESULTS: One hundred and twenty-five patients (median age, 50; male, 61.3%) were analyzed. Among 100,000 patients who visited the hospital, incidence was 24.1. Only two patients (1.6%) had a functional NET. The rectum (n = 99, 79.8%) was most common primary site and found in early stage. The prevalence by stages was 84.7% stage I, 8.9% stage IV, 4.8% stage II, and 1.6% stage III. The pathology grading was 74.5% grade 1, 12.7% grade 2, and 12.7% grade 3. Tumor stage correlated positively with pathologic grade (Spearman’s rank correlation coefficient, 0.644). CONCLUSIONS: Wide range of clinicopathological features of Korean gastroenteropancreatic NETs were demonstrated using WHO 2010 classification. Rectal NET was most frequent and found in early stage.

Pneumopericardium is a rare complication of pericardiocentesis, occurring either as a result of direct pleuro-pericardial communication or a leaky drainage system. Air-fluid level surrounding the heart shadow within the pericardium on a chest X-ray is an early observation at diagnosis. This clinical measurement and process is variable, depending on the hemodynamic status of the patient. The development of a cardiac tamponade is a serious complication, necessitating prompt recognition and treatment. We recently observed a case of pneumopericardium after a therapeutic pericardiocentesis in a 20-year-old man with tuberculous pericardial effusion.

Ankylosing spondylitis (AS) is occasionally accompanied by hematological malignancies such as myelodysplastic syndrome, acute myelogenous leukemia, or multiple myeloma. Chronic myelogenous leukemia (CML) is a myeloproliferative disorder associated with Philadelphia chromosome and is usually treated with imatinib, which inhibits tyrosine kinases. Although there have been reports of CML cases accompanied by several rheumatic diseases such as rheumatoid arthritis, Behcet's disease, systemic sclerosis, or undifferentiated spondylopathy, no studies have reported a case of CML with AS. We experienced a 50-year-old male patient who presented with buttock and low back pain and was diagnosed with both AS and CML. Magnetic resonance imaging showed sacroiliitis along with abnormal marrow infiltration, and a bone marrow biopsy confirmed the CML diagnosis. He was treated with imatinib, which was effective for the CML but not for the AS. This is the first case report of AS accompanied by CML.
