Abstract PDF

BACKGROUND
The incidence and clinical correlation of MALT1 translocation and numerical aberrations in Korean gastric MALT lymphoma patients have been rarely reported. We studied the incidence and clinicopathologic relationship of these chromosomal aberrations in Korean gastric lymphomas.
METHODS
Seventy-six gastric lymphomas, which consisted of 40 low grade MALT lymphoma, 4 high grade MALT lymphoma and 32 diffuse large B-cell lymphoma (DLBCL) cases, were analyzed for the detection of t(11;18) API2-MALT1, t(14;18) IgH-MALT1 and aneuploidies of chromosomes 3 or 18 using fluorescence in situ hybridization.
RESULTS
The t(11;18) was demonstrated in 3 low grade MALT lymphomas (7.5%) and one DLBCL, which was associated with advanced stage, deeper invasion, and disease progression or relapse. The t(14;18) was demonstrated in none of these cases. Trisomy 3 and 18 were detected in 8 (11%) and 11 of 76 cases (12.5%) respectively, and found only in translocation-negative cases. Two of 4 high grade MALT lymphomas showed trisomy 18. All patients survived with successful second treatment after progression or relapse.
CONCLUSIONS
The t(11;18) API2-MALT1 was not quite frequent in Korean low grade gastric MALT lymphomas and was associated with advanced clinical situations. Overall prognosis was good for long-term follow-up regardless of progression or relapse.

The Expression of Hypoxia Inducible Factor-1alpha and Its Correlation with the Expressions of Cyclin A1 and Cyclin B1 and the Clinicopathologic Factors of Uterine Cervical Carcinoma.: Ju Yeon Pyo, Jae Ho Cho, Hyunki Kim, Jong Pil Park, Young Tae Kim, Nam Hoon Cho; Korean J Pathol. 2009;43(1):13-19.; DOI: https://doi.org/10.4132/KoreanJPathol.2009.43.1.13

Abstract PDF: BACKGROUND
Hypoxia inducible factor-1alpha(HIF-1alpha) is a transcription factor for various target genes that are involved in adapting cells to hypoxia. It promotes cell proliferation and survival via modulation of such cell cycle regulators such as cyclin A1 and cyclin B1 in response to hypoxia. This is associated with local failure of radiotherapy, which renders a poor prognosis for cervical carcinoma.
METHODS
Using the tissue histologic sections and a tissue microarray of the archived biopsy and surgical specimens of uterine cervical carcinoma from 57 patients who were treated with radiation therapy alone, we performed immunohistochemical staining for HIF-1alpha and cyclin A1 and B1 to evaluate the correlations between the expressions of these proteins in tumors and the clinicopathologic parameters associated with the prognosis.
RESULTS
The large tumor cell nests and invasive front margins of the tumors showed comparatively intense immunoreactivity of HIF-1alpha. There was no significant correlation between the HIF-1alpha, cyclin A1 and cyclin B1 expressions and the clinicopathologic factors.
CONCLUSIONS
The HIF-1alpha expression showed marked intra-tumoral heterogeneity. The HIF-1alpha expression is neither a powerful predictor of resistance to radiotherapy nor is it a poor prognostic marker in cervical carcinoma patients who are treated with radiotherapy. The expressions of cyclin A1 and cyclin B1 are neither independently associated with the response of radiation therapy nor are they associated with the prognostic parameters of uterine cervical carcinoma.

Abstract PDF

BACKGROUND
Squamous cell carcinoma of the breast is very rare and it is considered to arise from metaplastic change of ductal carcinoma. Metaplastic squamous cell carcinoma (MSC) of the breast includes pure squamous cell carcinoma, metaplastic adenosquamous carcinoma and low grade adenosquamous carcinoma. Most of the cases of MSC of the breast were reported to have lymph node metastasis and this has a worse prognosis than that of conventional invasive ductal carcinoma.
METHODS
We collected 17 cases of MSC of the breast from 1,173 cases of breast cancer and analyzed the clinicopathological characteristics.
RESULTS
The age range was 31 to 69 years (mean age: 47.2). The mean tumor size was 3.6 cm. Twelve cases (70.6%) had a negative nodal status. The majority of the cases were of a high nuclear grade (grade III: 76.5%), and a high histologic grade (grade III: 88.2%). All the cases had no amplification of HER2, and they were negative for hormonal receptors, except for 2 cases with weak positivity. All the cases showed positivity for EGFR (3+: 14 cases, 1+: 3 cases). Clinical relapse was found in 3 patients on follow up and two of them expired due to lung and bone metastasis.
CONCLUSIONS
MSC is associated with high nuclear and histologic grades, a high EGFR expression and they are triple negative for ER, PR, and HER2. The EGFR immunopositivity of MSC suggests a basal-like subtype.

Abstract PDF

BACKGROUND
Genetic polymorphism of methylenetetrahydrofolate reductase (MTHFR), in association with the influence of MTHFR upon DNA methylation, may cause differences of the methylation profile of cancer. Thus, we investigated the relationship between the methylation status of prostate adenocarcinoma and the genetic polymorphism of MTHFR.
METHODS
We examined 179 cases of prostate adenocarcinoma for determining the genotypes of MTHFR 677 and 1298, the methylation status of 16 CpG island loci and the methylation levels of the LINE-1 and Alu repeats with using polymerase chain reaction/restriction fragment length polymorphism, methylation-specific polymerase chain reaction and combined bisulphite restriction analysis, respectively.
RESULTS
There was a higher proportion of the CT genotype of MTHFR 677 in the prostate adenocarcinoma than that in the normal control. The TT genotype of MTHFR 677 showed the highest frequency of methylation in six out of nine major CpG island loci, and these were which were frequently hypermethylated in prostate adenocarcinoma. The CT type showed the lowest methylation levels of LINE-1 and Alu among the MTHFR 677 genotypes. Interestingly, the CC type of MTHFR 1298 demonstrated favorable prognostic factors.
CONCLUSIONS
Our study is the first to examine the methylation profile of prostate adenocarcinoma according to the MTHFR genotypes. The differences of the cancer risk, the genomic hypomethylation and the prognosis between the MTHFR genotypes in prostate adenocarcinoma should be further explored.

Abstract PDF

BACKGROUND
Diabetic nephropathy is the most common cause of end-stage renal disease and it has various pathologic features. We investigated the clinicopathologic differences between the histologic classes of diabetic nephropathy.
METHODS
A total of 46 patients with diabetic nephropathy were evaluated. Morphologically, the renal lesions were divided into three categories: class 1, diffuse or nodular glomerulosclerosis: class 2, vascular change without evidence of glomerulosclerosis: and class 3, non-diabetic renal disease superimposed on diabetic glomerulosclerosis. We evaluated the laboratory findings and the histologic findings, including mesangial expansion, interstitial fibrosis and inflammation, arteriolar hyalinosis and tubular atrophy.
RESULTS
The proportion of each class was 32 cases (70%), 4 cases (9%) and 10 cases (21%), respectively. The clinical and laboratory data showed no significant difference among the classes. For the groups of class 1, the group with nodular sclerosis showed a higher serum creatinine level than did the diffuse group (p=0.003). IgA nephropathy was the most common non-diabetic renal disease superimposed on diabetic glomerulosclerosis in our study.
CONCLUSIONS
The patients with nodular glomerulosclerosis presented with a more progressed clinicopathological features than did the patients with class 1 diffuse glomerulosclerosis. We also found 21% of all the patients with diabetic nephropathy had superimposed non-diabetic renal disease in a Korean population.

Abstract PDF

BACKGROUND
The diseases that cause neonatal cholestasis display several overlapping clinical feature. Making the differential diagnosis using liver biopsy specimens from infants with neonatal cholestasis is important for delivering the proper treatment.
METHODS
We assessed the clinical manifestations, laboratory data, and histopathologic features of the pretreatment liver biopsy specimens from patients suffering with biliary atresia (n=66), intrahepatic bile duct paucity (n=15), and neonatal hepatitis (n=21).
RESULTS
The gender distribution was nearly equal for the patients with biliary atresia and intrahepatic bile duct paucity, whereas males predominated for the cases of neonatal hepatitis. Only the gamma-glutamyl transferase level differed significantly amongst the groups. The diagnostic features for making the differential diagnosis of bile duct lesions included marked bile ductular proliferation, severe fibrosis, and bile duct loss. The difference of the average percentage of portal tracts with bile duct loss was statistically significant between the patients with intrahepatic bile duct paucity (73.9%) and those patients with neonatal hepatitis (39.1%) (p<0.001).
CONCLUSIONS
Bile ductular proliferation, bile duct loss, and advanced fibrosis are useful for the differential diagnosis of neonatal cholestasis. Moreover, stricter diagnostic criteria for bile duct loss (more than 2/3 of bile ducts) should be applied for the definitive diagnosis of intrahepatic bile duct paucity, because bile duct loss also frequently occurs in infants suffering with neonatal hepatitis.

Abstract PDF: BACKGROUND
Intrahepatic cholestasis can occur early after living donor liver transplantation (LDLT). We investigated the changes in the expressions of the bile acid transporters and the liver histology in the patients who suffered with early cholestasis (EC) following LDLT.
METHODS
The histological differences between 15 graft livers with EC after LDLT and 5 graft livers with biliary stricture following LDLT were evaluated. The hepatic mRNA levels of the bile canaliculi transporters (BSEP, MRP2, MRP3, MDR1, MDR3, NTCP) in 40 (20 graft livers, 20 matched donor livers) liver biopsy tissues were analyzed by performing real-time reverse-transcription polymerase chain reaction (RT-PCR).
RESULTS
Microscopic examination revealed hepatocellular and/or bile canalicular cholestasis around acinar zone 3 in the livers of the patients with EC. In the livers with biliary stricture, the cholestasis was dominantly observed in the hepatocytic cytoplasm and in the bile ductules around the portal area rather than around acinar zone 3. The BSEP and MRP2 mRNA levels in the EC livers were significantly reduced by 44% and 23%, respectively (p=0.000), compared to the matched donor livers. The levels of MDR3 and NTCP mRNA in the EC livers increased by 738% (p=0.000) and 281% (p<0.01), respectively. The change of the expressions of the bile acid transporters in the patients with biliary stricture was less significant than that in the EC group.
CONCLUSIONS
These results suggest that the altered expressions of the bile acid transporters may play a role in the pathogenesis of EC following LDLT.

Functional Inactivation of pRb Associated with Cyclin D1- and Cyclin-dependent Kinase 4 Overexpression Plays A Key Role in Human Pituitary Tumorigenesis.: Na Hye Myong; Korean J Pathol. 2009;43(1):56-62.; DOI: https://doi.org/10.4132/KoreanJPathol.2009.43.1.56

Abstract PDF

BACKGROUND
Human pituitary adenoma (PA) is a common intracranial tumor, but the mechanism underlying tumorigenesis has not been established. Functional inactivation of retinoblastoma protein (pRb) following cyclin D1- and cyclin-dependent kinase (CDK) 4-dependent hyperphosphorylation is one of the most important mechanisms in tumor cell proliferation. We evaluated immunohistochemical expressions of cyclin D1, CDK4 and phosphorylated pRb (p-pRb) in 50 PAs to investigate a role for functional inactivation of pRb associated with cyclin D1/CDK4 overexpression in pituitary tumorigenesis and to correlate it with clinicopathologic variables.
METHODS
Fifty human PAs were immunohistochemically stained for cyclin D1, CDK4 and p-pRb (Thr 356). Correlations between their expression and the clinicopathologic characteristics were statistically analyzed.
RESULTS
Cyclin D1 and CDK4 were overexpressed in 56% and 64%, respectively; pRb was hyperphosphorylated in 64%. Forty one cases (82%) showed one or more of these altered expressions. Overexpressions of cyclin D1 and CDK4 were correlated with functional pRb inactivation. Cyclin D1 overexpression was associated with apoplexy and growth hormone production.
CONCLUSIONS
Functional inactivation of pRb associated with the cyclin D1/CDK4 overexpression might play a key role in human pituitary tumorigenesis. CDK4 worked in concert with cyclin D1 to hyperphosphorylate pRb. Pituitary apoplexy appeared to be associated with cyclin D1 overexpression.

Abstract PDF: The confirmative diagnosis of leptomeningeal metastasis depends on detecting malignant cells on the cytologic examination of cerebrospinal fluid (CSF). The presence of leptomeningeal metastasis is a very important factor to determine the aggressiveness of treatment. We analyzed 273 cases that were diagnosed as malignancies on the CSF cytology. The most common metastatic carcinoma was lung cancer (76 cases, 27.8%). There were 49 cases (17.9%) and 40 cases (14.7%) of breast and stomach cancers, respectively. There were 49 cases (17.9%) of lymphoma and 40 cases (14.7%) of leukemia. There were 19 cases of other types of cancer (6.9%). For the cases of primary lung cancer, there were 60 cases (78.9%) of adenocarcinoma and 7 cases (9.2%) of squamous cell carcinoma, but only 4 cases (5.3%) of small cell carcinoma. For the case of breast cancer, all of those were invasive ductal carcinoma and 25 cases (51.0%) were grade 3. Diffuse large B-cell lymphoma was the most common type of all metastatic lymphomas (22 cases, 44.9%) and lymphoblastic lymphoma was the second most common (8 cases, 16.3%). In our hospital, the most common leptomeningeal metastasis was adenocarcinoma of the lung, and breast cancer and lymphoma were the second most common. On CSF cytology, malignancies that have a tendency towards CSF metastasis should be carefully examined for to select the proper treatment.

Abstract PDF: Phyllodes tumor (PT) is a rare fibroepithelial tumor of the breast, and these tumors are subdivided into benign, borderline, and malignant tumors. The criteria for their histologic diagnosis have been relatively well-described. However, the cytologic diagnosis presents more difficulties and only a few cytologic studies concerned with their subclassification have been published. The objective of the current study is to describe the cytologic features of benign, borderline and malignant PTs in an attempt to distinguish one from the others. Cytohistologic correlation for 11 benign, 3 borderline and 3 malignant PTs was performed. For all these cases, the preoperative fine needle aspiration (FNA) findings were available for review. The features we examined were a necrotic background, cellularity, stromal tissue fragments, stromal pleomorphism and atypism, dissociated stromal cells and mitosis. The overall diagnostic accuracy of FNA for the PT grading was 88.2% (15/17). Two benign PTs were cytologically misinterpreted as "atypical epithelial and stromal cells" and "highly suspicious for ductal carcinoma". Nevertheless, the cytologic diagnosis and the grading of PTs on FNA were relatively reliable. Semiquantitative analysis for the cellular stromal tissue fragments, stromal pleomorphism and atypism, dissociated stromal cells and mitosis might be helpful for subclassifing PTs on FNA. In the case of encountering a markedly necrotic background, special concern about degenerative change such as infarction is needed.

Abstract PDF: Calcifying aponeurotic fibroma is a rare soft tissue tumor that mostly occurs in the distal extremities of children and adolescents. We report here on a case of calcifying aponeurotic fibroma of the right elbow in an 8-year-old boy, and the tumor was diagnosed by surgical excision. The patient complained of painless swelling and mild limitation of the range of motion of the elbow joint. Radiologically, the mass was ill-defined and showed stippled calcification with shallow bony erosion. Microscopically, the tumor was composed of spindle cells with nodular deposits of hyalination and calcification, and these deposits were surrounded by palisading polygonal plump cells. Immunohistochemically, the tumor showed a diffuse positive expression for CD99 and negativity for smooth muscle actin, S-100 protein and CD34. The patient has been well with no signs of recurrence during the 42 months after surgery.

Abstract PDF

This report represents a very rare case of a gastric adenocarcinoma that was coexistent with hepatoid adenocarcinoma and neuroendocrine carcinoma. A 77-year-old man was admitted to our hospital due to a huge ulcerofungating mass identified at the proximal body of the stomach. After a pathological diagnosis of the tumor as a poorly differentiated adenocarcinoma was made, the patient underwent a total gastrectomy with lymph node dissection. Microscopically, the tumor consisted of three morphologically distinct components-tubular adenocarcinoma, hepatoid adenocarcinoma and neuroendocrine carcinoma. The hepatoid adenocarcinoma component resembled a hepatocellular carcinoma and produced alpha-fetoprotein. The neuroendocrine carcinoma component was positive for chromogranin and synaptophysin immunostains. This is an example of the diverse morphological and immunophenotypical differentiation of gastric carcinomas.

Abstract PDF: Spontaneous pneumothorax occurs in a variety of lung diseases. Primary or metastatic lung cancers are rare, but important causes of pneumothorax. We report here on a case of pulmonary metastasis of thyroid papillary carcinoma that initially presented as spontaneous pneumothorax. A 32-year-old male with no history of thyroid disease underwent wedge resection of the lung due to recurrent pneumothorax. Histologically, the pleura and subpleural lung parenchyma revealed several micronodular lesions and randomly scattered glandular structures with mild cytological atypia. The cells were characterized by their overlapped hypochromatic nuclei with longitudinal grooves and inconspicuous nucleoli. On the additional sections, we found a few intranuclear inclusions and colloid-like material in the follicular structures. The glandular cells were immunoreactive for thyroglobulin, TTF-1, CK 7 and HMW-CK and they were focally immunoreactive for EMA, but they were negative for S100, chromogranin and CEA. The Ki-67 labelling index was 4%. Neck ultrasonography revealed an ill-defined hypoechoic nodule in the left lobe of the thyroid. The diagnosis of conventional, classical papillary carcinoma was made by both the cytology and the total thyroidectomy specimen. Pathologists should conduct a through histologic examination for the patients with recurrent spontaneous pneumothorax to search for the underlying causes.
