Pleomorphic xanthoastrocytoma is histologically characterized by marked cellular pleomorphism of lipid-laden neoplastic astrocytes and bizarre giant cells showing mitotic figures and high cellularity. Inspite of its ominous-looking microscopic features, howerver, the prognosis is usually favorable. This tumor develops mainly in the supratentorial area of young people and frequently involves the leptomeninges. We experienced a case of pleomorphic xanthoastrocytoma in 18 year-old-male. In addition to the cellular pleomophism, the prominent reticulin fibers surround the individual tumor cells or the tumor cells nests. Immunohistochemical staining and electron microscopy revealed glial fibrillary acidic protein(GFAP) expression and pericytoplasmic basal lamina in the tumor cells.

Hemangiopericytoma was first described by Stout & Murray in 1942 and was an uncommon soft tissue tumor thought to be derived from vascular pericytes. Approximately 10-15% of the cases occur in children have a propensity to develop in the region of head, neck and lower extremities. We experienced a case of congenital hemangiopericytoma of small bowel in a male neonate who showed vomiting and abdorninal distension. We reported a case of congenital hemangiopericytoma of small bowel with brief review of related literature.

PURPOSE: We measured pulmonary epithelial permeability by Tc-DTPA radioaerosol clearance in patients with diabetes and correlated with the presence of microangiopathy to understand the pathophysiology of pulmonary microangiopathy and evaluate Tc-DTPA radioaerosol clearance as a diagnostic test to assess pulmonary microangiopathy. MATERIALS AND METHODS: We performed ' Tc-DTPA radioaerosol scan in 10 normal subjects, 10 asym-ptomatic smokers, 20 diabetic patients without history of smoking (10 with microangiopathy, 10 without microangiopathy). Tc-DTPA clearance half-time (T1/2) was calculated, then compared with the result of chest radiography and pulmonary function test. RESULTS: Chest radiography and pulmonary function test were normal in all subjects. There were no significant difference of clinical or laboratory characteristics between these groups except age. The diabetic patients with micraangiopathy were significantly older (p<0.05). The T1/2of normal subjects and asyrnptomatic smokers were significantly different (65.2+23.7min vs 39.6+9.8min, p<0.05). For diabetic patients with microangiopathy, the T, was 90 5+46.5min and significantly delayed when compared with those of normals and asymptomatic smokers (p<0.05). However, the T1/2of diabetic patients without microangiopathy, 70.0+12.7 min, was not significantly different from those of normals or asyrnptomatic smokers (p>0.05). No significant correlation was found between the T1/2and spirometric parameters including DLcc>, FVC, FEV>, FEV(/FVC (%) and FEF)5-75g in all subjects, and between the T1/2 and duration of diabetes in diabetic patients. CONCLUSION: Eventhough the influence of age cant be excluded, delayed Tc-DTPA clearance half-time (T1/2)in diabetic patients with microangiopathy indicates decreased pulmonary cspillary permeability as one of the pathophysiologic results of pulmonary microangiopaththy. Further studies are needed in larger number of age matched control and diabetic patients to evaluate the diagnostic efficacy.

PURPOSE: The aim of this study was to determine the frequency, epidemiology and the clinical manifestation of human metapneumovirus (hMPV) infection in Korean children. METHODS: From February 2010 to January 2012, we collected nasopharyngeal aspiration from 1,554 children who were hospitalized for acute lower respiratory tract infections at the Department of Pediatrics, Severance Children's Hospital. hMPV was detected by performing reverse transcriptase-polymerase chain reaction (RT-PCR). The medical records of the patients with positive results were retrospectively reviewed. RESULTS: We detected hMPV in 99 of the 1,554 hospitalized children. The mean age of the hMPV infected children was 25 months, and 87% of the illnesses occurred between April and June. The most common diagnoses were pneumonia (73%) and bronchiolitis (16%). The clinical manifestations included cough, fever, respiratory distress, hoarseness, tachypnea, and wheezing. Coinfection with other respiratory viruses was found in 43 children (43%). CONCLUSION: hMPV is one of the major virus causing acute respiratory tract infection in the age between 13 months and 48 months old with peaks during April to June. Reports of hMPV in Korea has been increasing but additional studies are required to define the epidemiology and the extent of disease caused by hMPV to determine future development of this illness in Korean children.

7.Flow cytometric DNA analysis of gastric cancer--correlation with histology and clinical outcome.
Journal of Korean Medical Science 1993;8(5):348-354
Nuclear DNA content was analysed by means of flow cytometric measurements in 103 patients with gastric carcinomas, using paraffin-embedded archival tissue. DNA aneuploidy was found in 40 cases (38.8%). The mean DNA index of aneuploid tumors was 1.45(range 1.13 to 2.37). No significant association between ploidy and either age, sex, tumor location, size, stage, growth pattern, or histologic type was found. However, the incidence of aneuploidy was higher in high grade carcinomas than in low grade carcinomas; the incidence of aneuploidy was 10%, 68.8%, and 45.8% for Grade II, III, and IV carcinomas, respectively, as compared with Grade I carcinomas which were all diploid. On statistical analysis, Abnormal cellular DNA content was significantly correlated with high histologic grade (P<0.005). Patients with aneuploid cancer (39.2%) had a poorer prognosis than those with diploid cancer (70.0%) based on (P<0.01). The 2-year survival rate for advanced gastric carcinoma. Therefore, DNA ploidy might be a useful prognostic factor in cases of advanced gastric cancer.

Pleomorphic (undifferentated) carcinoma is a rare histologic type of carcinomas of the gallbladder and an atypical carcinoid is thought to be an intermediated type between carcinoid tumor and small cell carcinoma. Dense core "neurosecretory" granules can be found in the above mentioned tumors. We experienced a case of a double tumor of the gallbladder in a 51-year old male patient. Grossly, a large solid mass, about 5.0 cm in diameter, was found in the fundic portion and the neck portion also had a small 1.5 cm-sized polypoid mass. Microscopically, these lesions had features of pleomorphic carcinoma and atypical carcinoid, respectively. Immunohistochemically, they manifested reactivity for neuron specific enolase. Ultrastructural study revealed neurosecretory granules in the cytoplasms of tumor cells of the fundic and neck masses. Although light microscopic features of these tumor masses are quite different, we consider that these tumors represent a spectrum of neuroendocrine differentiation.
