BACKGROUND
Recent studies have demonstrated that insulin-like growth factor II mRNA-binding protein 3 (IMP3) is expressed in malignant tumors of various organs but not in normal tissue. We investigated IMP3 expression in various benign lesions, premalignant lesions and carcinomas of the stomach.
METHODS
IMP3 immunohistochemical staining was performed on 24 benign gastric lesions, 24 gastric adenomas, and 322 gastric carcinomas.
RESULTS
IMP3 was not expressed in benign gastric lesions including adenomas with low-grade dysplasia, but was expressed in 17% of adenomas with high-grade dysplasia, and in 44% of carcinomas. As the carcinomas were in the advanced stage, they expressed IMP3 more frequently and strongly. Patients with IMP3-positive tumors had poorer survival than those with negative tumors.
CONCLUSIONS
IMP3 expression in gastric carcinoma may be related to tumor invasion and metastasis, and is an independent risk factor for poor prognosis.

Abstract PDF

BACKGROUND
Pathologists occasionally have difficulty in distinguishing cholangiocarcinoma from benign reactive cells on the biliary cytology. We estimated the diagnostic value of insulinlike growth factor II mRNA binding protein 3 (IMP3) on biliary cytology specimens.
METHODS
We selected 40 patients who had undergone a biliary cytology examination and whose diagnoses were confirmed by biopsy. The IMP3 expression was evaluated by immunohistochemical staining in both the tissue and the cytology specimens. Their histologic diagnoses were cholangiocarcinoma (n = 34), high grade dysplasia (n = 2), low grade dysplasia (n = 1) and non-biliary tumor or no tumor (n = 3).
RESULTS
On the histology, all the cases of cholangiocarcinoma or high grade dysplasia were positive for IMP3 (36/36). The low grade dysplasia or the normal bile ducts in the other 4 cases were negative for IMP3 (0/4). Of the 36 cases diagnosed as cholangiocarcinoma or high grade dysplasia histologically, 29 cases were positive for IMP3 on the cytology (29/36; sensitivity, 80.6%). Of the 4 cases without cholangiocarcinoma or high grade dysplasia, 1 case was weakly positive for IMP3 on the cytology. The histologic diagnosis of this case was hepatocellular carcinoma. Except for this hepatocellular carcinoma case, the specificity of IMP3 on the cytology was 100%.
CONCLUSIONS
IMP3 is a useful diagnostic marker for cholangiocarcinoma on cytology.

Abstract PDF: BACKGROUND
Gastric metaplasia of the duodenum is thought to be associated with the pathogenesis of duodenal ulcer. We investigated the pathological features of gastric metaplasia and their relation to age, gender, duodenal ulcer and H. pylori infection.
METHODS
We reviewed the duodenal endoscopic findings of 535 patients (age range: 0 to 87) and the microscopic slides of the duodenal biopsy specimens.
RESULTS
Gastric metaplasia was first noted at the age of 4 and the prevalence increased thereafter until the patients' mean age reached about 30. The prevalence of gastric metaplasia was 53.7% after 30 years of age. As the metaplasia became severer, it became more polypoid in appearance and it more often contained parietal cells. Gastric metaplasia was more frequently observed or severe in duodenal ulcer patients, in males and in the first portion of the duodenum than in patients without duodenal ulcer, in females and in the second portion, respectively. There was a lack of correlation between gastric metaplasia and H. pylori infection.
CONCLUSIONS
The prevalence and/or severity of gastric metaplasia of the duodenum increases with age, and it is thought that most duodenal ulcers develop in the areas of gastric metaplasia.

Abstract PDF: BACKGROUND
Prior studies of p16, p53, and Ki-67 expression have suggested that these markers may be preferentially expressed in cervical neoplasms. The purpose of this study was to assess the expression and clinical significance of p16, p53 proteins, and the Ki-67 labeling index in the cervical lesions.
METHODS
We analyzed 54 uterine cervical specimens obtained by surgical biopsy. The expression of p16, p53 proteins, and Ki-67 was evaluated by immunohistochemical methods. The immunohistochemical findings were then correlated with the histologic diagnosis.
RESULTS
Positive scores for p16, p53, and Ki-67 were seen in 75% (6/8), 0% (0/8), and 13% (1/8) of low grade intraepithelial lesions (LSIL), respectively, and 100% (23/23), 17% (4/23), and 74% (17/23) of high grade intraepithelial lesions (HSIL), respectively, and 100% (10/10), 20% (2/10), and 70% (7/10) of invasive squamous cell carcinomas, respectively. Both normal epithelium and inflammatory lesions scored negative for these three markers in all of the 13 cases. p16 and Ki-67 expression correlated with the severity of uterine cervix lesions.
CONCLUSIONS
p16 and Ki-67 are complementary surrogate biomarkers for cervical squamous intraepithelial neoplasia. However, immunohistochemical expression for p53 has no correlation with the grade of cervical squamous intraepithelial neoplasia.

Abstract PDF: Solitary fibrous tumor (SFT) most commonly affects the pleura and these tumors have been recently reported to be found in unusual locations. We describe here a solitary fibrous tumor of the urinary bladder that was removed from a 79-year-old man having a history of gross hematuria and dysuria. Transabdominal ultrasonography showed a huge soft tissue mass in the urinary bladder. The cut surface of the tumor showed a grayish-white, hemorrhagic and gelatinous appearance. Necrosis was not found. Microscopically, the tumor showed a proliferation of spindle or ovoid cells that were intervened by a collagenous stroma. A variety of growth patterns was identified but the so-called patternless pattern was the predominant one. The spindle cells had almost no mitotic figures, and there was very little or no nuclear atypia. Immunohistochemical stains showed a strong reactivity for CD34 and a focal reactivity for bcl-2. The ultrastructure of the tumor cells showed mesenchymal-myofibroblastic traits.

Abstract PDF: It was reported that the main cause of intraepithelial neoplasm and squamous cell carcinoma of the uterine cervix is human papilloma virus infection, and that the expression of p16 is increased in cells infected by human papilloma virus. We performed an immunocytochemical staining for protein p16 in 17 cases of cervocovaginal smears initially diagnosed as atypical squamous cells of undetermined significance, to know whether the staining could help the differentiation of neoplastic cells from reactive atypical cells. Of 17 smears, 6 were diagnosed finally as high grade intraepithelial neoplasm or invasive squamous cell carcinoma by follow-up biopsy and smear, and 5 of the 6 were positive for p16. Three were diagnosed as koilocytosis, and one of them was weakly positive for p16. Eight were diagnosed as reactive atypical cells, and all of them were negative for p16. We thought that immunocytochemical staining of p16 in cervocovaginal smears could help the differentiation of neoplastic cells from reactive atypical cells.

Abstract PDF: BACKGROUND
It has been believed that there is a pure mucus-secreting cardiac mucosa (CM), about 2 cm in length, below the gastroesophageal junction. However, recent reports suggest that CM might not be located at the most proximal portion of the stomach. The purpose of this study is to investigate the relationships between the types of proximal gastric mucosa and patients' age, sex, their condition regarding the Helicobacter pylori infection, and severity of chronic gastritis.
METHODS
Two pieces of mucosal tissue from the most proximal portion of the stomach and the antrum of 44 pediatric and 85 adult patients were examined using a light microscope. A rapid urease test was performed on the other antral specimen from each patient.
RESULTS
In 46 (90.2%) out of 51 patients with aged 30 or under, only the pure acid-secreting oxyntic mucosa (OM) was present at the most proximal portion of the stomach. The cardiac or mixed oxyntocardiac mucosa (OCM) increased in prevalence with age. The CM or OCM was found more frequently in patients with H. pylori infection or severe gastritis than in those without H. pylori infection or those with mild gastritis. However, there were no statistically significant differences within the same age groups.
CONCLUSIONS
Although the OCM is sometimes present at the most proximal portion of the stomach, the CM is absent or rare in individuals under the age of 30. The OCM or CM increases in prevalence with age. There are no direct relationships between the type of proximal gastric mucosa and a patient's gender, his/her condition regarding the H. pylori infection, and severity of chronic gastritis.

Abstract PDF: BACKGROUND
Helicobacter pylori is present mainly in the gastric mucous layer. However, the mucous layer, along with the bacteria, is lost during conventional tissue processing in which formalin is used for fixation. The purpose of this study is to ascertain - if the mucous layer is preserved by using Carnoy solution as a fixative - whether the detection rate of H. pylori is increased in pediatric patients.
METHODS
Five pieces of gastric mucosal tissue were obtained from the gastric antrum and the body of one hundred pediatric patients. One of the specimens was fixed with formalin. Another specimen was fixed with Carnoy solution. The tissue sections were stained with hematoxylin-eosin and immunohistochemically stained for H. pylori. For reference, a rapid urease test was performed on the remaining three specimens.
RESULTS
In the formalin-fixed tissue, the detection rate of H. pylori was 13% in the gastric antrum and 12% in the body (overall 16%). In the Carnoy solution-fixed tissue, the mucous layer was preserved and the detection rate of H. pylori was 23% in the antrum and 27% in the body (overall 28%). The positive rate of the rapid urease test was 26% in the antrum and 28% in the body (overall 29%).
CONCLUSIONS
When the number of H. pylori is small in the gastric mucosa, the bacteria may not be detected by conventional histologic methods. In that case, the detection rate of H. pylori may be increased by using Carnoy solution, rather than formalin, as a tissue fixative.

Abstract PDF: A microscopic examination of 1,000 cases of gastroscopic biopsy specimens revealed that the prevalence and severity of chronic gastritis, neutrophilic infiltration, and Helicobacter pylori infection increased with advancing age until the age reached about 40, but they decreased thereafter in accordance with the increasing prevalence of intestinal metaplasia. The prevalence and severity of Helicobacter pylori infection, chronic gastritis, and neutrophilic infiltration were proportionately related to each other and to gastric peptic ulcer, but inversely related with intestinal metaplasia and gastric carcinoma. The results suggested that chronic gastritis and gastric peptic ulcer may be associated with Helicobacter pylori infection and that if these lesions persist, intestinal metaplasia may develop with decreased severity of chronic gastritis and Helicobacter pylori infection but, instead, increase of the risk of gastric carcinoma. And it is thought that the cause of the high incidence of gastric carcinoma in Korea may be related to the fact that chronic gastritis and Helicobacter pylori infection develop earlier in life and therefore the prevalence of intestinal metaplasia is higher in Korea than in other countries.

Abstract PDF: The limb-body wall malformation complex is a sporadic congenital anomaly characterized by protean manifestations. The diagnosis is based upon the presence of at least two out of craniofacial anomaly, body wall defect, and limb abnormalities. We present a case of limb-body wall malformation complex. This case shows abdominal and pelvic wall defects with eventration of the viscera. It also shows an absence of right kidney, polycystic left kidney, absence of external genitalia and anus, and lower extremity abnormalities. The right lower extremity is absent and the deformed left leg shows malformed foot-like structure attached to the shin in addition to a normally positioned left foot. Our patient is the first case of complete absence of the external genitalia associated with limb-body wall malformation complex in Korean publications and the seventh in English publications.

Abstract PDF: Forty eight female Sprague-Dawley rats received a subcutaneous implant containing 12.5 mg estradiol ant the age of 3 weeks. Three rats were killed in 1, 2, 3, 4, 6 weeks and in every month during 2~12 months after implantation, and the breasts were examined by light microscope. In all rats, enlargement of terminal end buds was obseved in 1~2 weeks, maximum development of hyperplastic alveolar nodules in 3 weeks, and marked dilatation and secretion of alveoli or ducts in 1~12 months after implantation. Ductal epithelial hyperplasia was observed in 27 rats and carcinomas developed in 23 rats in 2~12 months after implantation. It was thought that the changes induced by estradiol are more similar to the human breast lesions, compared with changes induced by chemical carcinogens such as dimethylbenzanthracene(DMBA), because breast carcinomas developed in close relationship with ductal epithelial hyperplasia in both estradiol-treated rats and humans, but not in DMBA-treated rats.
