Background

High-risk human papillomavirus (HR-HPV) infection and abnormal p53 expression are closely involved in carcinogenesis of squamous cell carcinoma (SqCC) of uterine cervix. Recent studies have suggested that virus-induced endoplasmic reticulum (ER) stress modulates various cell survival and cell death signaling pathways. The C/EBP homologous protein (CHOP) is associated with ER stress-mediated apoptosis and is also involved in carcinogenesis of several human cancers. We hypothesized that CHOP is involved in the carcinogenesis of uterine cervical cancer in association with HR-HPV and/or p53.

Methods

Immunohistochemistry was used to analyze CHOP and p53 protein expression of tissue sections from 191 patients with invasive cancer or preinvasive lesions of the uterine cervix (61 cases of SqCC, 66 cases of cervical intraepithelial neoplasia [CIN] III, and 64 cases of CIN I).

Results

CHOP was expressed in 59.4% of CIN I, 48.5% of CIN III, and 70.5% of SqCC cases. It was also significantly more frequent in invasive SqCC than in preinvasive lesions (p=0.042). Moreover, CHOP expression significantly correlated with HR-HPV infection and p53 expression (p=0.009 and p=0.038, respectively).

Conclusions

Our results suggest that CHOP is involved in the carcinogenesis of the uterine cervix SqCC via association with HR-HPV and p53.

Abstract PDF

Background

Cortactin and focal adhesion kinase (FAK) are two important components among actin cross-linking proteins that play a central role in cell migration.

Methods

The aims of this study were to evaluate the expression of cortactin and FAK in normal colorectal mucosa and colorectal adenocarcinoma (CRC) using tissue microarray of 2 mm cores to correlate their expression with other clinicopathological factors and, investigate their prognostic significance.

Results

Twenty (9%) and 24 cases (11%) of normal colorectal mucosa were immunoreactive for cortactin and FAK. In addition, 184 (84%) and 133 cases (61%) of CRCs were immunoreactive for cortactin and FAK, respectively. Cortactin expression was associated with histologic differentiation and FAK expression. Cortactin, but not FAK expression was also correlated with poor overall and relapse-free survival and served well as an independent prognostic factor for poor survival.

Conclusions

Cortactin expression, in association with FAK expression, may plays an important role in tumor progression. Furthermore, it may also be a satisfactory biomarker to predict tumor progression and survival in CRC patients.

Abstract PDF

Background

E-cadherin, cortactin, and matrix metalloproteinase (MMP)-9 have roles in tumor development or progression, but their expression has not been fully investigated in pseudoepitheliomatous hyperplasia (PEH) and squamous cell carcinoma (SCC) of the head and neck.

Methods

We evaluated the immunohistochemical expression of E-cadherin, cortactin, and MMP-9 in 29 cases of PEH and 97 cases of SCC. Additionally, we evaluated their relationship with clinicopathologic factors and prognostic implications in SCC.

Results

Thirty-five cases of SCC showed reduced expression of E-cadherin, whereas none of the PEH did. A total of 20 cases and 11 cases of SCC were immunoreactive for cortactin and MMP-9, respectively, whereas none of the PEH did. In SCC, reduced expression of E-cadherin was correlated with cortactin expression and invasion depth. Cortactin expression was correlated with differentiation, T classification, and recurrence and/or metastasis. MMP-9 expression was correlated with invasion depth. Cortactin expression was correlated with poor overall survival and relapse-free survival and it was an independent prognostic factor.

Conclusions

The reduced expression of E-cadherin and the expression of cortactin may be helpful for the differential diagnosis of PEH and SCC. Furthermore, cortactin expression in association with reduced E-cadherin expression is correlated with poor prognosis in SCC.

Abstract PDF: Metastases of malignant tumors to the oral region from distant sites are uncommon. A 45-year-old man with painless gingival swelling was diagnosed with adenocarcinoma of the lung. On cytology, clusters of tumor cells on mucous background revealed enlarged nuclei, indistinct cell borders, and irregular nuclear membranes. Some cells showed nuclear inclusions, nuclear grooves and small nucleoli. These findings are indicative of metastatic adenocarcinoma. We present a case of gingival metastasis from a lung adenocarcinoma.

Abstract PDF

Glomus tumors of the stomach are rare and are usually found as a solitary, intramural lesion. Here, we report a case of a gastric glomus tumor in a 60-year-old woman diagnosed by endoscopic ultrasound-guided fine-needle aspiration cytology. Endoscopic ultrasound revealed a 4 x 3 cm-sized, round, isoechoic mass at the fourth layer of the gastric wall. Smears revealed cohesive clusters of small, uniform, round to polygonal cells with scant cytoplasm and round, hyperchromatic nuclei with homogeneous chromatin. Immunocytochemistry by liquid-based cytology was positive for smooth muscle actin. The cytologic diagnosis of a glomus tumor was confirmed by a specimen from the laparoscopic resection. Although the cytologic features of glomus tumors are quite distinctive, an immunocytochemical stain from a liquid-based cytology preparation can further help to ascertain the diagnosis.

Abstract PDF

BACKGROUND
Molecular tools for tissue profiling generally require collection of fresh frozen tissues (FFT) as sources of high-quality DNA and RNA. Nowadays, researchers carry out large-scale, multi-center studies and they request inter-institutional minimal intrinsic bias, some fundamental similarities, and the same standardized and validated procedures.
METHODS
This study reports standardized quality control procedure for fresh frozen tissue of the National Biobank of Korea.
RESULTS
The main procedures for quality control for FFT are as follows: records related to sample collection such as labeling of samples, transport temperature, lag time from excision of tissue to freezing, and sample size were reviewed for all fresh frozen samples. The stability of RNA and DNA in fresh frozen tissue was evaluated for 3% of collected samples and purity was assessed (ratio of the absorbance at 260 and 280 nm) as was integrity (agarose gel electrophoresis). Stained hematoxylin and eosin sections were reviewed by a pathologist to confirm the diagnosis and to assess how representative the frozen sample was.
CONCLUSIONS
We introduced that the quality-control criteria for fresh frozen tissue of the NBK. We expect that this study contributes to standardization of collection, storage, and quality control of fresh frozen tissue.

Abstract PDF

BACKGROUND
Nerve growth factor (NGF) has been suggested to participate in tumor progression and it can interact with its receptor p75NGFR. In the present study, we investigated the expressions of NGF and p75NGFR in hepatocellular carcinoma (HCC).
METHODS
We performed immunohistochemistry for NGF, p75NGFR and PCNA in 45 cases of HCCs, and examined the relationships between the clinicopathologic factors and the immunohistochemical results.
RESULTS
NGF was detected in 84.4% (38/45) of the tumor cells and in 64.4% (29/45) of the non-tumorous hepatocytes. Furthermore, a NGF expression was present in 28.9% (13/45) of the endothelial cells in the HCCs, but in 80% (36/45) of the endothelial cells in the non-tumor liver tissue. The tumor cells were negative for p75NGFR in all the HCCs. Although a p75NGFR expression was present in all the nerve fibers in the non-tumor liver tissues, it was markedly reduced (42.2%; 19/45) in the HCCs and a p75NGFR expression was observed at the sinusoids or around the large vessels. The HCCs expressing NGF, either in the tumor cells or the endothelial cells, showed a larger size than those HCCs that didn't express NGF. The NGF positive tumors showed a tendency toward a higher PCNA-labeling index than did the negative tumors.
CONCLUSIONS
The changed localization of the NGF expression and the decreased expression of p75NGFR are associated with hepatic carcinogenesis. We suggest that a NGF expression may contribute to the progression of HCC.

Abstract PDF: Histologic, immunohistochemical and ultrastructural studies were performed on 6 cases of undifferentiated thyroid carcinoma to study the histogenesis of the undifferentiated thyroid carcinoma, to determine the most useful markers for diagnosing these tumors and to investigate the nature of osteoclast-like giant cells rarely observed in these tumors. For the immuno-histochemical study, a panel of antibodies to epithelial (cocktailed keratin, low molecular weight keratin, CEA), mesenchymal(vimentin, desmin, actin, FVIIIRAg) endocrine(calcitonin, chromogranin), lymphocytic(LCA), histiocytic(alpha-l-ACT, alpha-1-AT, lysozyme, CD68), and Schwann cell(S-100 protein) markers were used. The following results were obtained; 1) Well differentiated carcinoma was associated with 2 cases of spindle cell type and 1 case of giant cell type of undifferentiated thyroid carcinoma and a transitional zone between the well differentiated and undifferentiated lesions was observed. 2) All of the examined cases expressed keratin, and 3 tumors expressed CEA. 3) All the mesenchymal markers, LCA, S-100 protein, calcitonin, and chromogranin were not expressed. Vimentin was coexpressed with keratin in 4 cases. 4) Osteoclast-like giant cells were observed in 1 case of spindle cell type. They expressed CD68 but not keratin. 5) Ultrastructural study revealed the desmosomes between the tumor cells and non-neoplastic, follicular, thyroid epithelial cells. The above results indicate that undifferentiated thyroid carcinoma originates from follicular epithelial cell, keratin is the most useful marker for diagnosis of this tumor, and the osteoclast-like giant cells are histiocytic in nature and reactive, rather than neoplastic.

Abstract PDF: Adrenal pseudocysts are uncommon lesions which usually occur as a result of hemorrhage within the adrenal tissue. Adrenal hemorrhage is usually associated with severe stress, sepsis, pregnancy, syphilis, leukemia, or anticoagulant therapy but during steroid therapy, it is very rare. We report a case of adrenal pseudocyst that resulted from hemorrhage into the adrenal gland and is probably related to the exogenous administration of steroids. The patient was a 57-year-old woman who was treated with oradexon for 20 years for the treatment of a maculopapular lesion on her thigh as well as for arthritis. She underwent a right adrenalectomy due to the adrenal cystic mass. The wall of the cystic mass was composed of a thick layer of hyalinized fibrous tissue with remnants of adrenal cortical tissue on the outer aspect. The inner surface had no lining cells and the wall of the cyst contained many calcified plaques with hemosiderin pigment.

Abstract PDF: In this study, the prevalence of Hepatitis B virus(HBV) DNA in the needle biopsied paraffin embedded liver tissues of chronic hepatitis B patients by rapid nested PCR was examined. DNA was extracted by NaOH with boiling, and amplified by rapid air thermocycler with glass capillary tubes and nested PCR with two primer sets specific for the surface and the core genes of HBV. The PCR results were compared to that of serum HBeAg, serum HBV DNA by dot blot hybridization with a radioactive DNA probe, and tissue immunohistochemical (HBsAg/ HBcAg) studies. Among 44 patients with chronic hepatitis with serum HBsAg positivity, HBV DNA could be detected by PCR in 43 liver tissues (98%). This results were comparable to the positive rates of 94%(31/33) for serum HBV DNA, 80%(35/44) for serum HBeAg, and 59%(26/44) and 75%(33/44) for tissue HBsAg and HBcAg, respectively. The accordance rate between tissue PCR and serum DNA probe testing was 91%. The results indicate that HBV DNA detection by rapid nested PCR of paraffin embedded liver tissues by needle biopsy is a more sensitive method to detect the HBV DNA carrier than the serum HBeAg or tissue HBsAg/HBcAg status, and is well correlated with the result of serum HBV DNA probe testing. Therefore this method is a practical indicator for the diagnosis and replication status in retrospective analysis.

Abstract PDF: Lymphocytic hypophysitis is an autoimmune disorder of the pituitary gland which usually occurs in a woman in the postpartum period. Diabetes insipidus is not a major clinical feature of this disorder. We report a case of a 22-year-old man with lymphocytic hypophysitis which presented with diabetes insipidus and also involved his cavernous sinus. This represents the seventh reported and the youngest case of a man with lymphocytic hypophysitis. A comparative study of all six male patients is also presented. We suggest diabetes insipidus should be added to the spectrum of clinical manifestations of this disorder.

Abstract PDF: Carcinoid tumors of the appendix are common incidental findings, but appendiceal tumors with histologic features of both carcinoids and adenocarcinomas are rare, and their biologic behavior and histogenesis are still unclear. We report a case of goblet cell carcinoid of the appendix in a 54-year-old male, who exhibited pain in the right lower abdomen. Microscopically, the tumor contained smooth-bordered, widely separated nests composed of tumor cells with abundant mucin. The principal tumor cell type had a close resemblance to the normal goblet cell. Histochemically, the tumor cells revealed positive reaction for PAS and alcian blue stain. Immunohistochemically, the tumor showed strong reactivity for carcinoembryonic antigen, chromogranin and, neuron specific enolase but none for cytokeratin and epithelial membrane antigen.

Abstract PDF: In the present study, immunohistochemical detection of p53 oncoprotein was performed to determine whether the grade of differentiation and the histologic type of gastric adenocarcinoma, and the degree of atypia accompanied with adenoma can be related to p53 mutation. Paraffin sections of 22 gastric adenomas and 56 gastric adenocarcinomas were examined for the overexpression of p53 oncoprotein with the avidin-biotin peroxidase complex staining procedure. The obtained results were as follows; 1. All the 22 cases of adenomas and 16 cases of well differentated adenocarcinomas showed uniformly negative staining. 2.Seven of 18 cases of moderately differentiated adenocarcinomas(39%), and five of 30 cases of poorly differentiated adenocarcinomas(17%) exhibited p53 protein expression. 3. Three of 29 cases of diffuse type (10%) and 9 of 19 cases of intestinal type(47%) exhibited p53 protein expression. These results suggest that p53 mutation is important in carcinogenesis of the intestinal type of gastric adenocarcinoma, and there is no correlation between the differentiation of gastric adenocarcinoma and the degree of p53 oncoprotein overexpression.

Abstract PDF: Menetrier's disease is characterized by enlarged gastric folds with foveolar hyperplasia and cystic dilatation of gastric glands. The additional biochemical features of hypoproteinemia, hypochlorhydria, and increased gastric mucus are often encountered. The pathogenesis and etiologic factors have not been clearly defined. In this report, we present two cases of Menetrier's disease in the stomach, one occurring in a 38-year-old male, associated with massive hematemesis, and the other in a 39-year-old male. Grossly, both cases showed marked giant gastric rugal folds resembling cerebral convolutions, sparing the antral portion. Microscopically, the giant gastric rugal folds consisted of the striking foveolar hyperplasia accompanied by an occasional presence of the smooth muscle fibers from the muscularis mucosa. The immunohistochemical stain revealed an intense positive reaction for transforming growth factor-alpha (TGF-alpha) and epidermal growth factor receptor (EGF-R) in the majority of mucous cells throughout the gastric mucosa and parietal cells, but did not reveal for epidermal growth factor (EGF). We suggested that TGF-alpha and EGF-R might be involved in the pathogenesis of Menetrier's disese.

Abstract PDF: We evaluated 1,000 consecutive endometrial curettage samples obtained over a 30 month period. The clinico-pathologic correlation was analysed according to Hendrickson's five criteria based on the practical view. The causes of uterine bleeding in decreasing order of occurrence were as follows: 1) hormonal imbalance lesions (49.2%) encompassing glandular and stromal breakdown suggesting anovulatory bleeding, proliferative phase endometrium, and disordered proliferative endometrium, 2) pregnancy associated lesions (24.2%), 3) organic lesions (13.5%), 4) endometrial hyperplasia (6.9%), and 5) inadequate specimen (6.2%). According to age, pregnancy related lesions were most frequent in the third decade. In the fourth, fifth, and sixth decades, hormonal imbalance lesions were the most common cause. In approximately 30% of the samples, there were two or three morphologic patterns such as anovulatory bleeding with an endometrial polyp, postabortal bleeding with inflammation, and glandular-stromal dissociation with a polyp, which suggested there was a variable histologic morphology in the same disease spectrum. Using immunohistochemical techniques we studied the hormonal dependency of bcl-2 oncoprotein in anovulatory bleeding, endometrial hyperplasia, and proliferative endometrium. 70% of anovulatory bleeding specimens showed weak positivity in the epithelial cytoplasm, and all cases of endometrial hyperplasia and carcinoma showed a strong positivity. These results suggest that there is a estrogenic hormonal dependency of apoptosis in the endometrium.
