An inverted hyperplastic polyp (IHP) found in stomach is rare and characterized by downward growth of hyperplastic mucosal component into the submucosa. Because of such characteristic, IHP can be misdiagnosed as subepithelial tumor or malignant tumor. In fact, adenocarcinoma was reported to have coexisted with gastric IHP in several previous reports. Because only 18 cases on gastric IHP have been reported in English and Korean literature until now, pathogenesis and clinical features of gastric IHP and correlation with adenocarcinoma have not been clearly established. Herein, we report a case of gastric IHP which was initially misdiagnosed as gastrointestinal stromal tumor and resected using endoscopic submucosal dissection. Literature review of previously published case reports on gastric IHP is also presented.

OBJECTIVETo analyze the correlation of the length and volume of intravesical prostatic protrusion (IPP) with bladder outflow obstruction (BOO) in patients with BPH and to find a simple method for the diagnosis of the disease.
METHODThe length and volume IPP were measured by transrectal ultrasound for 87 patients with BPH, the diagnosis of BOO was made by urodynamic tests and the correlation of the length and volume of IPP with BOO was analyzed, and reanalyzed 3 months after oral medication of a-blocker. The length and volume of IPP were measured again during the operation in 54 of the cases to confirm the ultrasound findings.
RESULTSBOO was diagnosed in 51 of the patients. The coefficient of correlation between the length of IPP and BOO and that between the volume of IPP and BOO were 0.53 and 0.47 (P < 0.01). Not considering the dynamic factors, they were 0.69 and 0.62 (P < 0.01), respectively. BOO was confirmed in patients with the length of IPP > 1.0 cm or the volume > 1.5 ml. There was no significant difference between the results of transrectal ultrasound and the findings during the operation concerning the length and volume of IPP (P > 0.05).
CONCLUSIONThere is a close correlation between the length and volume of IPP and BOO, which can be conveniently applied to the diagnosis of BOO in BPH patients.

OBJECTIVETo explore the CT features of ground-glass nodules (GGN) including preinvasive lesions [atypical adenomatous hyperplasia (AAH) and adenocarcinoma in situ (AIS)], minimally invasive adenocarcinoma (MIA) and invasive adenocarcinoma (IAC).
METHODSNinety-seven GGN lesions confirmed by operation pathology were included in this study. The lesions were divided into three groups: preinvasive lesion group (24 cases), MIA group (39 cases), IAC group (34 cases). The lesion size, 3-dimensional ratio, 2-dimensional ratio in axial images, lesion density, shape, speculation, lobulation, air-containing space and pleural indentation on the preoperative CT images in the three groups were analyzed and compared with pathological results. The data were statistically analyzed using SPSS 17.0.
RESULTSAll preinvasive lesions presented as pure GGN on CT image, most showed round-like shape, clear and smooth border. MIA presented as pure GGN or mixed GGN on CT image, most showed round-like shape, with a clear and smooth border. IAC most presented as mixed GGN on CT image, often showed irregular shape. Speculation, lobulation, air-containing space and pleural indentation displayed gradually increasing from preinvasive lesions to MIA and IAC. There were statistically significant differences in lesion size, CT density, shape, air-containing space, speculation, pleural indentation and long diameter of solid component between the MIA and IAC groups (P < 0.05 for all). There were statistically significant differences in CT density values and long diameters of solid component of the lesions between the preinvasive lesion group and MIA group (P < 0.05). The AUC of solid component of the preinvasive lesion group and MIA group was 0.705, and that of the MIA and IAC groups was 0.814.
CONCLUSIONComprehensive analysis of the CT image features of GGNs, especially the solid component in the lesions, may help to the preoperative and differential diagnosis of preinvasive lesions, MIA and IAC.

OBJECTIVETo analyze the correlation between the size of prostatic middle lobe hyperplasia and the degree of bladder outlet obstruction (BOO) in patients with benign prostatic hyperplasia (BPH).
METHODSThis study included 131 BPH patients who presented with dysuria between May 2008 and June 2010. The prostate volume and intravesical prostatic protrusion (IPP) were measured by transabdominal ultrasound, Qmax and detrusor pressure at Qmax (P(det@ Qmax)) detected by urodynamic examination, the obstruction degree and detrusor contractility judged using the LinPURR Figure, and the AG value calculated (AG = P(det@ Qmax) -2Qmax). The degrees of BOO were compared between different groups of IPP by variance analysis, and the prostate volume, IPP and AG values underwent Bivariate correlation analysis.
RESULTSIPP was highly positively correlated with BOO when it was > 10 mm (r = 0.821, P < 0.01), while PV and BOO had a lower correlation (r = 0.475, P < 0.01). There was also a high positive correlation between IPP and P(det@ Qmax) (r = 0.865, P < 0.01).
CONCLUSIONA close correlation exists between prostatic middle lobe hyperplasia and BOO, and evaluating IPP by ultrasound is a reliable method to determine the degree of BOO.

OBJECTIVETo study significance and limitations of the ratio of free to total prostate specific antigen (f/t PSA) in differential diagnosis between prostate cancer and benign prostatehyperplasia (BPH) with total PSA (tPSA) levels between 4 and 10 ng/ml.
METHODSWe analysed retrospectively 180 prostate cancer and BPH patients who were diagnosed and treated in our hospital from October 1998 to October 2002 and had serum tPSA levels between 4 and 10 ng/ml. Of the 180 patients, 36 (20%) were histologically confirmed as prostate cancer and 144 (80%) BPH. The tPSA and free PSA (fPSA) in serum were measured by micropartical enzyme immunoassay. Prostate volume was measured by transabdominal ultrasonography. We chose Student's t-test for comparison between prostate cancer and BPH groups. The correlation between prostate volume and f/t PSA was analyzed using Pearson's correlation coefficient.
RESULTSThe mean values of tPSA and f/t PSA were 6.75 ng/ml and 0.17 in patients with prostate cancer, 6.48 ng/ml and 0.25 in patients with BPH. The mean value of tPSA wasn't significantly different between patients with prostate cancer and BPH (P > 0.05). However, the mean value of f/t PSA of patients with prostate cancer was significantly lower than that of patients with BPH (P < 0.01). Furthermore, there were significant and positive correlation between prostate volume and f/t PSA in both groups with prostate cancer and BPH (prostate cancer group's correlation coefficient (r = 0.50, P < 0.01); BPH group (r = 0.24, P < 0.01). There was significant difference in f/t PSA between prostate cancer and BPH patients with prostate volumes more than 40 cm(3) (P < 0.05), but not between these two groups with prostate volumes more than 40 cm(3) (P > 0.05).
CONCLUSIONThe f/t PSA is significant in differential diagnosis between prostate cancer and BPH with tPSA levels between 4 and 10 ng/ml. But prostate volume has an effect on f/tPSA. The f/tPSA has diagnostic value of differentiation only when the prostate volume is less than 40 cm(3).

8.Peritoneal tuberculosis mimicking advanced ovarian carcinoma: distinction based on CT findings.
Chinese Journal of Oncology 2004;26(2):122-125
OBJECTIVETo evaluate the computed tomography (CT) findings of peritoneal tuberculosis mimicking advanced ovarian carcinoma for better understanding of the CT manifestations and accurate preoperative diagnosis.
METHODSCT findings of 18 cases with tuberculous peritonitis clinically simulating advanced ovarian cancer but pathologically proved otherwise were retrospectively reviewed.
RESULTS1. Masses with solid and cystic structures were found in 6 cases and tumor-like flakes were found in 7 cases in the adnexal regions. The solid components and tumor-like flakes were moderately to markedly enhanced with dynamic CT scanning. 2. The peritoneum was smooth and slightly thickened in 10 cases; irregular thickening was seen in 4 cases, and patches of calcification in 3 cases. Thickened peritoneum with pronounced enhancement was noted in 7 cases. 3. Omentum with flake-like thickening was noted in 11 cases, coarse reticulate thickening in 2 cases and omental cakes in 2 cases. The margin of the thickened omentum with enhancement was ill-defined. 4. Nodular and stripe-like thickening of the mesentery was noted in 16 cases. 5. Ascites was present in all of the 18 cases, being encapsulated in 14 of them. 6. Lymphadenopathy was seen in 9 cases, all at located in the diaphragmatic levels. Enhancement of the lymph nodes was marked in 8 of the 8 patients examined. They appeared as ring-like (> 1 cm in diameter) or uniform ( CONCLUSIONCT examination combined with clinical manifestations helps differentiate tuberculous peritonitis from advanced ovarian cancer.

Up-to-date imaging modalities such as three-dimensional dynamic contrast-enhanced CT (3D CT) and MRI may contribute to detection of hypervascular nodules in the liver. Nevertheless, distinguishing a malignancy such as hepatocellular carcinoma from benign hypervascular hyperplastic nodules (HHN) based on the radiological findings is sometimes difficult. Multiple incidental liver masses were detected via abdominal ultrasonography (US) in a 65-year-old male patient. He had no history of alcohol intake and no remarkable past medical history or relevant family history, and his physical examination results and laboratory findings were normal. 3D CT and MRI showed numerous enhanced nodules with hypervascularity during the arterial phase. After US guided liver biopsy, the pathological diagnosis was HHN. To date, several cases of HHN have been reported in patients with chronic alcoholic liver disease or cirrhosis. Herein, we report on a case of HHN in a patient with no history of alcoholic liver disease or cirrhosis.

Castleman's disease is an uncommon disorder characterized by benign proliferation of the lymphoid tissue that occurs most commonly in the mediastinum. Although unusual locations and manifestations have been reported, involvement of the renal parenchyma and sinus, and moreover, manifestations as cardiac tamponade are extremely rare. Here, we present a rare case of Castleman's disease in the renal parenchyma and sinus that also accompanied cardiac tamponade.
