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.

Bacterial meningitis results in significant neurologic dificits despite in spite of much effort in the treatment of the disease. This study was performed to determine the incidence of caustive organisms and to correlate between the organisms and computed tomographic (CT) findings with clinical outcome of bacterial meningitis in newborns and infants. We analyzed the brain CT and clinical records of 15 infants who had been diagnosed as bactrial meningitis by CSF culture. We found that the most common organisms were Group B streptococcus in neonates withou no neurologic complications in all but one and Hemophilus influenza in infants whose clinical outomes were poor in all except one. CT findings related with poor prognosis in this study were cerebral edema, basal cistermal obliteration & enhancement, and cerebral infarction on initial CT and ventriculomegaly on follow-up CT. We concluded that CT diagnosed intracranial complications of bacterial meningitis well and could contributed to better treatment of bacterial meningitis.

A case of a 58-year-old man with malignant fibrous histiocytoma (MFH) of the right ventricle is reported light and electron microscopically. This is the first case of MFH of the heart in the Korean literature. A tendency for malignant fibrous histiocytoma of the heart to occur in the left atrium of young women is suggested; this sarcoma's usual location is in the soft tissue of elderly men. The tumor consisted of spindle cells arranged in a focal storiform patterns, clusters or sheets of histocyte-like cells, benign and malignant giant cells, inflammatory cells, scattered mitotic figures and anaplasia of stromal cells. In ultrastructure the constituent of cells of the tumor are primitive mesenchymal cells, histiocytoid cells and fibroblast like cells including giant cells.

An endodermal sinus tumor is a malignant germ cell tumor that usually arises in the gonads, but on rare occasion occurs in extragonadal locations. Our case was that of a 3 year old girl who complained of a rapid growing orbital mass. On histologic examination it revealed the typical picture of an endodermal sinus tumor and it also disclosed a positive reaction for alphafetoprotein using an immunoperoxidase technique. An orbital exenteration was performed followed by chemotheraphy, but the patient died 5 months after the onset of the disease.

Obesity is caused by interactions of energy consumption, amount of food intake, physical activity and etc, and these elements are influenced by genetic factors. Obesity related genes which have been known by now are over 200. One of these is Kir6.2 which forms the pore region of K(ATP) channel, and genetic variation of which may result in altered beta-cell electrical activity, insulin secretion, glucose homeostasis, and increased susceptibility to type 2 diabetes. Therefore, the purpose of this study was to examine the relationship between Kir6.2 E23K polymorphism and fat distribution or metabolic profiles in Korean. A total of 164 patients who visited Dongsan Medical Center Obesity Clinic from February 2004 to December 2005, were enrolled in this study. Screening for Kir6.2 polymorphism carried out by PCR-RFLP analyses. We divided this group into three groups E/E, E/K, K/K. Serum lipid and blood glucose were measured by autoanalyzer. Visceral fat amount and subcutaneous fat by abdominal CT, total fat mass by DEXA were measured. The subjects of E/E, E/K, K/K genotypes were 24, 79, and 61, respectively. The results of ANOVA analysis was that subjects with the K/K genotypes had more visceral fat amount (P<0.05) and higher total cholesterol levels (P<0.05) than E/E subjects group. Visceral fat amount and serum total cholesterol were significantly different according to Kir6.2 E23K polymorphism. Therefore, Kir6.2 polymorphism may act on fat distribution in Koreans.

Eighteen cases of osteonecrosis of the femoral head associated with macromolecular polyvinylpyrrolidone (PVP) deposition were analysed on the basis of clinical, radiologic and pathologic features. The cases were observed during 8 years period from January, 1974 to December, 1981. The pathogenesis of the osteonecrosis of the femoral head due to PVP storage in reticuloendothelial system were discussed in detail. Parenteral administration of high-molecular PVP in repeated, long duration led to osteonecrosis of the femoral head. Storage of PVP in the histiocytes of the bone marrow resulted in osteonecrosis of the femoral head followed by microciculation disturbance. PVP-induced osteonecrosis were manifested as multiple foci of necrosis involving not only the femoral head, other long bones around joints, but also the visceral reticuloendo-thelial system characterized by infiltrates of histiocytes laden with PVP. The patients with PVP induced osteonecrosis complianed multiple joint pain in their early course of the disease. On roentgenogram, osteonecrosis were often noted in the hip, shoulder, knee, and ankle in order or frequency. Foamy histiocytes laden with PVP were characteristic on hematoxylin-eosin stain diagnostic on Weigert's elastica, phosphotungstic acid hematoxylin, and Congo red stains. As far as rationale of the treatment concerning a number of staging systems for Osteonecrosis, the choice of surgical procedures were similar to those given by W.F. Enneking et al. In the series, we have performed two hips in total surface replacement, 26 hips in total hip replacement mostly for 3rd generation-configuration of Charnley prosthesis. In addition, one case for free vascularized fibula graft and trans-trochanteric rotational osteotomy after Sugioka were also included for this study. The result of treatment was rather optimistic. However, complications have occured in 4 hips of 3 patients which required removal of whole prosthetic components. Therefore, we underwent revisional surgery in three out of four hips subsequently during the short post-poerative follow-up. These will be published in the future.

Congenital mesoblastic nephroma(CMN) is an important differential diagnosis of a renal mass occurring in the newborn or in early childhood. It was first described by Bolande as a separate disease entity distinct form Wilms' tumor. In 1974, Beckwith has predicted that this tumor has a pathologic spectrum with classic congenital mesoblastic nephroma at one extreme, unequivocally mallignant spindle cell sarcomas at the other, and intermediate "gray zone" lesions of indeterminate biologic significanse. In 1986, Joshi has described "atypical mesoblastic nephroma" as a potentially aggressive variant of CMN, which shows atypical gross and microscopic features such as hemorrhage, necrosis, high cellularity, and mitotic index. We report of a case of atypical mesoblastic nephroma presenting in a 38 days-old male infant. Grossly, the tumor involved the upper and midportion of the left kidney. On section, the cut surface was fleshy, grayish-white, and homogeneous. Microscopically, the tumorshowed high degree of cellularity and arrangement of fusiform cells in sheets and vague interlacing bundles. The individual tumor cells showed fusiform to oval nuclei, indistinct scanty pale-eosinophilic cytoplasm and many mitotic figures.

Benign hemangioma of the mediastinum is rare. This slowly growing tumor is described as well circumscribed, cystic, hemorrhagic tumor. Histologically it can be differentiated into capillary or cavernous form. We present a case of mediastinal hemangioma. A 20-year-old-man was presented with a slowly growing posterior mediastinal mass of 6 years duration, 8x6 cm in size. The mass was relatively well defined but focally invasive. Microscopically, it was differentiated into vessels of capillary, cavernous, and venous patterns. A solid cellular proliferation with inconspicuous capillary lumens was focally seen. The stroma between variable-sized vessels showed marked myxoid change associated with some smooth muscle bundles and adipose tissue. Ultrastructurally, areas of solid cellular proliferation showed formation of lumens. These lumens were lined by active endothelial cells showing plasmalemmal vesicles and Weibel-Palade bodies on the abluminal surface.
