We experienced two unusual cases of tumor-like polypoid lesions involving the rectosigmoid colon. They could not be readily classified into any well known polypoid tumors of the rectosigmoid colon, but appeared to have some similarities to the previously documented "eroded polypoid hyperplasia (EPH)". A collective review of our seven cases of solitary(More)
A case of xanthoma of the liver in a 61-year-old Korean woman with multiple myeloma, hyperlipidemia and xanthoma of the skin is described. Microscopically, the liver showed a multiple xanthomatous collection of foamy histiocytes as well as diffuse sinusoidal infiltration of the foam cells. This hepatic accumulation of foam cells seems to be related to(More)
Intravascular papillary endothelial hyperplasia (IPEH) is a benign vascular lesion which is thought to represent an unusual form of organizing thrombus. A case of IPEH in the kidney of a 7-year-old girl is described. She suffered from intermittent flank pain and gross hematuria for 6 months. On radiological examinations, well-defined hypoechoic lesions were(More)
Anatomical descriptions of the maxillary sinus are critical in pathological diagnosis and the treatment planning of surgical procedures. This study was undertaken to develop a new technique for simulating anatomical structures and to clarify the morphological and clinical characteristics of the maxillary sinus. Thirty-three hemi-sectioned Korean heads were(More)
Gonadoblastoma and dysgerminoma developed in a 24-year-old phenotypic female patient with 46,XY pure gonadal dysgenesis. This patient presented with primary amenorrhea. Clinical characteristics showed a typical stigmata of gonadal dysgenesis: primary amenorrhea, sexual infantilism, a small uterus and bilateral streak gonads. A 46,XY karyotype was made by(More)
In this paper, we propose a fast PU decision method to reduce encoder complexity. We use an early PU decision in each CU-level based on spatio-temporal analyses and depth correlations. We also consider a classification of motion activity. Experimental results show that the encoding complexity can be reduced by up to 37.98% on average in the random access(More)
The benefits of radio-chemotherapy in HIV-negative primary central nervous system (CNS) lymphomas were analyzed in 40 patients, who received radiotherapy to the brain or craniospinal axis with the total dose of 4460-5940 cGy to the primary tumor. Radiotherapy was followed by systemic chemotherapy, mainly with the cyclophosphamide, doxorubicin, vincristine(More)
Transferrin receptor (TR) performs the major function of binding and internalizing its specific iron-loaded ligand, transferrin, and its expression is closely linked to the proliferation status of the cell. This study was undertaken to elucidate TR expression in the hyperplastic lesion of hepatocyte in chemically induced hepatic carcinogenesis. The(More)
