Background
In the present multi-institutional study, the prevalence and clinicopathologic characteristics of non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) were evaluated among Korean patients who underwent thyroidectomy for papillary thyroid carcinoma (PTC).
Methods
Data from 18,819 patients with PTC from eight university hospitals between January 2012 and February 2018 were retrospectively evaluated. Pathology reports of all PTCs and slides of potential NIFTP cases were reviewed. The strict criterion of no papillae was applied for the diagnosis of NIFTP. Due to assumptions regarding misclassification of NIFTP as non-PTC tumors, the lower boundary of NIFTP prevalence among PTCs was estimated. Mutational analysis for BRAF and three RAS isoforms was performed in 27 randomly selected NIFTP cases.
Results
The prevalence of NIFTP was 1.3% (238/18,819) of all PTCs when the same histologic criteria were applied for NIFTP regardless of the tumor size but decreased to 0.8% (152/18,819) when tumors ≥1 cm in size were included. The mean follow-up was 37.7 months and no patient with NIFTP had evidence of lymph node metastasis, distant metastasis, or disease recurrence during the follow-up period. A difference in prevalence of NIFTP before and after NIFTP introduction was not observed. BRAF^V600E mutation was not found in NIFTP. The mutation rate for the three RAS genes was 55.6% (15/27).
Conclusions
The low prevalence and indolent clinical outcome of NIFTP in Korea was confirmed using the largest number of cases to date. The introduction of NIFTP may have a small overall impact in Korean practice.

Abstract PDF

Patients with Beckwith-Wiedemann syndrome (BWS) are predisposed to developing embryonal tumors, with hepatoblastoma being the most common type. Our patient showed hemihypertrophy, macroglossia, and paternal uniparental disomy in chromosome 11 and was diagnosed with BWS. When the patient was 9 months old, a 2.5×1.5 cm oval hypoechoic exophytic mass was detected in the inferior tip of his right liver. Preoperative imaging identified it as hepatoblastoma; however, histologic, immunohistochemistry, and electron microscopic findings were compatible with adrenal cortical neoplasm with uncertain malignant potential. The origin of the adrenal tissue seemed to be heterotopic. Here, we describe for the first time an adrenal cortical neoplasm with uncertain malignant potential arising in the heterotopic adrenal cortex located in the liver of a patient with BWS.

Abstract PDF

Background
The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) has standardized the reporting of thyroid cytology specimens. The objective of the current study was to evaluate the nationwide usage of TBSRTC and assess the malignancy rates in each category of TBSRTC in Korea.
Methods
Questionnaire surveys were used for data collection on the fine needle aspiration (FNA) of thyroid nodules at 74 institutes in 2012. The incidences and follow-up malignancy rates of each category diagnosed from January to December, 2011, in each institute were also collected and analyzed.
Results
Sixty out of 74 institutes answering the surveys reported the results of thyroid FNA in accordance with TBSRTC. The average malignancy rates for resected cases in 15 institutes were as follows: nondiagnostic, 45.6%; benign, 16.5%; atypical of undetermined significance, 68.8%; suspicious for follicular neoplasm (SFN), 30.2%; suspicious for malignancy, 97.5%; malignancy, 99.7%.
Conclusions
More than 80% of Korean institutes were using TBSRTC as of 2012. All malignancy rates other than the SFN and malignancy categories were higher than those reported by other countries. Therefore, the guidelines for treating patients with thyroid nodules in Korea should be revisited based on the malignancy rates reported in this study.

Abstract PDF

In recent years throughout Korea, the use of ultrasound-guided core needle biopsy (CNB) has become common for the preoperative diagnosis of thyroid nodules. However, there is no consensus on the pathology reporting system for thyroid CNB. The Korean Endocrine Pathology Thyroid Core Needle Biopsy Study Group held a conference on thyroid CNB pathology and developed guidelines through contributions from the participants. This article discusses the outcome of the discussions that led to a consensus on the pathology reporting of thyroid CNB.

Abstract PDF

Fibroepithelial stromal polyp (FSP) is a benign lesion that can occur at various sites, including the lower female genital tract. In rare cases, however, it may exhibit hypercellularity, bizarre cytomorphological features, and atypical mitoses resulting in an overdiagnosis as a malignant tumor despite its benign clinical course. Recently, we experienced one case of a 30-year-old pregnant woman with cellular pseudosarcomatous FSP that was initially diagnosed as a malignant fibrous histiocytoma at a primary clinic. In addition to describing the rare features of this case, we wish to increase awareness about this benign lesion which will be essential for avoiding unnecessary radical surgery or chemoradiation treatment.

Abstract PDF

BACKGROUND
This study was done to see if there were correlations between anatomic and molecular parameters such as microvessel density (MVD), lymphatic vessel density (LVD), and vascular endothelial growth factor receptor (VEGFR)-3 expression and various clinical parameters for papillary thyroid carcinomas of size > 1.0 cm (PTCs) and size < or = 1.0 cm (papillary thyroid microcarcinomas, PTMCs). PTMCs were divided into two subgroups (0-5 mm and 6-10 mm).
METHODS
We analyzed 197 thyroid carcinomas including 113 PTCs and 84 PTMCs. Tissue samples form 30 patients from each group matched for clinical characteristics were selected for immunostaining.
RESULTS
Although PTCs and PTMCs showed significant differences in clinical characteristics, they did not show significant difference in MVD, LVD, or VEGFR-3 expression. There was a significantly higher LVD in the PTMC subgroup with the larger tumors but no difference in clinical characteristics. LVD was higher in patients > 45 years old (more apparent in the PTC group) and LVD had suggestive correlations with multicentricity and extrathyroidal extension depending on analytic conditions.
CONCLUSIONS
Since LVD showed variable correlations with clinical variables for papillary carcinoma of the thyroid depending on analytic conditions, the individually planned treatments based on overall clinicopathological factors are advised.

Abstract PDF

BACKGROUND
This study was done to obtain comprehensive data on changes in the structural components of the enteric nervous system in pediatric patients with intestinal pseudo-obstruction (IPO). We evaluated routinely processed, in formalin-fixed tissues by quantitative morphometric analysis. In addition, we used formalin-fixed tissue to explore the possibility of using previously proposed diagnostic criteria to evaluate frozen serial sections for intestinal neuronal dysplasia (IND) type B and hypoganglionosis.
METHODS
We analyzed data for 19 IPO cases. Morphometric analysis for quantification of ganglia and ganglion cells (GCs) was done for the myentric and the submucous plexus. In addition, we determined the presence of immature GCs and the distribution of nerve fibers and interstitial cells of Cajal (ICC).
RESULTS
Nine patients showed combined hypoganglionosis, IND, and decreased ICC; others showed various combinations of these. Several morphometric factors were significantly different between patient groups as well as being different than the control group.
CONCLUSIONS
Our pediatric IPO cases showed extensive overlapping of pathological findings. And the findings suggest the utility of using previously proposed morphometrically measured factors in multiple frozen sections as diagnostic criteria for IND type B and hypoganglionosis in formalin-fixed tissue.

Abstract PDF

BACKGROUND
Regulatory T cells (Tregs) may contribute to the immunological hyporesponsiveness against hepatitis B virus (HBV), and this can result in chronic infection. Tregs suppress the T cell responses directed against HBV and they protect hepatocytes by down-regulating the immune responses that cause liver damage, but the role of Tregs has not been well characterized.
METHODS
Fifty four patients were selected and classified into three groups (12 were in the immune-tolerance phase, 35 were in the immune-clearance phase and 7 were in the asymptomatic virus carrier phase). We examined the frequency of CD3+, CD4+ & CD8+ T cells and forkhead box P3 (FoxP3)+ Tregs in the needle-biopsied liver tissue by performing immunohistochemistry.
RESULTS
The FoxP3+ Tregs were mainly located at the portal tracts. In the immune-clearance phase, the frequency of FoxP3+ Tregs was significantly increased compared to that of the immune-tolerance group and the asymptomatic carrier group. Increased FoxP3+ T cells were observed in the patients with a higher histologic inflammatory index. No correlation was observed among the numbers of FoxP3+ Tregs, the serum alanine aminotransferase level, detection of HBeAg and the HBV-DNA viral load.
CONCLUSIONS
FoxP3+ Tregs may play important roles in suppressing the immune response to HBV and the complete elimination of HBV.

Abstract PDF

BACKGROUND
Differentiation of viral hepatitis from acute cellular rejection (ACR) after liver transplantation can be difficult because of overlapping histological features. Here we investigated clinicopathologic characteristics of 311 liver allograft biopsies and searched for characteristic histopathological features that would facilitate the differential diagnosis between hepatitis B virus (HBV) infection and ACR. METHODS: A retrospective clinicopathologic examination of 311 liver allograft biopsies consisting of clinically proven ACR or HBV infection was performed. Immunohistochemical staining for HBcAg and HBsAg was done for 64 allograft biopsies showing HBV infection. RESULTS: Moderate to severe bile duct damage, diffuse centrilobular necrosis and centrilobular inflammation (p<0.000, for each) were more frequently observed in cases of ACR, whereas diffuse acidophilic bodies and spotty necrosis (p<0.000, for each) were more prevalent in cases of HBV infection. Immunopositivity for HBcAg (n=60, 93.8%) was higher than that for HBsAg (n=14, 21.9%) CONCLUSIONS: The presence of moderate to severe bile duct damage, diffuse centrilobular necrosis and centrilobular inflammation was a characteristic feature of ACR, whereas diffuse distribution of acidophilic bodies or spotty necrosis was the only characteristic feature of HBV infection. HBcAg was a more sensitive immunohistochemical marker than HBsAg for detecting HBV infection in liver allograft biopsies.

Abstract PDF: In the investigation of superficial lymphadenopathy of unknown cause, fine needle aspiration (FNA) cytology plays an invaluable role. It enables the differentiation of benign lymphadenopathy from lymphoid and non-lymphoid malignancies, obviating the need for open biopsy, and allowing the triage of patients. Cytopathologists should be familiar with the typical FNA patterns of benign lymphadenopathy, and recognize and differentiate among categories. In a minority of cases of benign lymphadenopathy, FNA can render a specific diagnosis. Benign lymphadenopathies are generally categorized into reactive lymphoid hyperplasia (RLH), inflammatory or infectious processes, and benign lymphoproliferative disorders. RLH characteristically presents with a heterogeneous and polymorphous smear composed of normal cellular constituents of lymph nodes, in contrast with the homogeneous or monomorphic smear of most lymphomas. The caveat is that various malignant disorders may also present with polymorphous populations. It is also important to recognize thatbenign lymphoid smears may sometimes contain atypical cells that raise the suspicion of malignancy. Clinical information should always be the integral part of the diagnostic criteria in FNA of lymphadenopathy. If there is any doubt about the benign nature of the smear, it is prudent to suggest biopsy and ancillary studies.

Abstract PDF: BACKGROUND
Lymphocytic gastritis (LG) is defined as an infiltration of more than 25 intraepithelial lymphocytes (IELs) per 100 surface epithelial cells, and the histological differential diagnosis of LG and residual mucosa associated lymphoid tissue (MALT) lymphoma can be difficult. Helicobacter pylori (H. pylori) is regarded as one of the possible causes of LG, but its clinicopathologic features of LG have not been clarified in Korea, which has a much higher prevalence of H. pylori infection than Western countries. We analyzed the clinicopathologic findings of LG in Korean patients and compared the cytologic findings of IELs of LG with those of MALT lymphoma.
METHODS
Sixty six cases of LG and 59 cases of MALT lymphoma were selected and clinicopathologic features were analyzed.
RESULTS
Eighteen cases (27.3%) of LG were found to be associated with H. pylori infection. The IELs in LG were found to diffusely and regularly infiltrate in the epithelium, but MALT lymphoma showed patchy IELs. IELs in LG and MALT lymphoma were CD 8+T lymphocytes and CD20+B lymphocytes, respectively. The mean nuclear size of IELs in LG was 4.37 micrometer, which was significantly smaller than those in MALT lymphoma (5.19 micrometer).
CONCLUSION
LG, a rare variant of chronic gastritis is partly associated with H. pylori infection and more complex unknown causative factors. In addition to the immunophenotyping, the nuclear sizes of IELs can be helpful in the differential diagnosis of LG and residual MALT lymphoma.

Abstract PDF: A Listeria monocytogenes infection is relatively rare in healthy adults. However, the chance of an infection increases almost 17 times in pregnancy due to changes in the immune function. A Listeria monocytogenes infection results in characteristic gross and microscopic features in the placenta, including multiple yellowish nodules showing microscopic intervillous abscess and intervillositis. We describe the placental findings of a Listeria monocytogenes infection that was complicated by maternal sepsis, myocarditis and congestive heart failure. The infection was discovered in the 34th week of a twin gestation in a 28 year-old woman. This case should emphasize the importance of this condition to pathologists. Antibiotic treatment was started based on the placental histologic findings before a maternal blood culture confirmed growth of Listeria monocytogenes. Both the mother and twin babies were healthy at the time of this report.

Abstract PDF: BACKGROUND
The 14-3-3 sigma (sigma) protein has a negative regulatory role in the cell cycle progression of the. Down-regulation or overexpression of the 14-3-3 sigma protein has been reported in various human cancers.
METHODS
Immunohistochemistry for the 14-3-3 sigma protein was performed in non-neoplastic bile duct cells, intraductal papillary neoplasms of the liver (IPNL), mass-forming intrahepatic cholangiocarcinomas (ICC) and non-papillary extrahepatic cholangiocarcinomas (ECC). We investigated the methylation status of the 14-3-3 sigma gene in 45 cases of these 3 tumor groups.
RESULTS
The non-neoplastic bile duct cells demonstrated negative or weakly positive cytoplasmic immunoreactivity for the 14-3-3 sigma protein and no methylation of the 14-3-3 sigma gene. Overexpression as well as negative immunoreactivity associated with hypermethylation of the 14-3-3 sigma protein was observed in 16 (69.6%) of 23 cases of IPNL, in 21 (63.6%) of 33 cases of mass-forming ICC and in 27 (71.1%) of 38 cases of non-papillary ECC. Negative immunoreactivity was increased in the invasive IPNL (4/6, 66.7%), as well as in the poorly differentiated cases of mass-forming ICC (8/12, 66.7%) and the non-papillary ECC (5/8, 62.5%).
CONCLUSIONS
The similar rates for the abnormal expression of the 14-3-3 sigma protein among the three groups of biliary neoplasms indicate its general association with biliary carcinogenesis. Furthermore, the loss of the 14-3-3 sigma protein may be involved in the tumor progression and differentiation in the biliary carcinogenesis.

Abstract PDF: We report on two cases of localized amyloidosis involving the ureter. The patients were a 64-year-old woman with right upper quadrant pain (case 1) and a 36-year-old woman suffering from left flank pain and intermittent gross hematuria (case 2). An intravenous pyelography of case 1 revealed multiple filling defects in the entire right ureter, whereas retrograde pyelography in case 2 showed diffuse narrowing in the mid and lower portions of the left ureter. Localized amyloidosis of the ureter was diagnosed in the two cases, and both had amyloid deposit in the renal pelvis and the urinary bladder in case 1, and in the contralateral ureter and the renal pelvis in case 2. Right nephroureterectomy was performed in case 1, but a segmental resection of the ureter with preservation of the kidney was administered in case 2. These two cases demonstrate that ureteral amyloidosis can be associated with amyloid deposition in the renal pelvis and the urinary bladder. Although ureteral amyloidosis is a rare occurrence, it should be considered in the differential diagnosis of ureteral obstruction to avoid unnecessary radical surgery.

Abstract PDF: Primary mucinous cystic neoplasms of the retroperitoneum in women are rare and show histologic features similar to their ovarian or pancreatic counterparts. We present three cases of primary retroperitoneal mucinous neoplasms of variable malignant potentials including a cystadenocarcinoma in a 50-year-old woman, a cystic neoplasm of borderline malignancy in a 31-year-old woman, and a cystadenoma in a 67-year-old woman. All cases showed histologic features similar to mucinous tumors of the ovary. Immunohistochemical study demonstrated positivity for calretinin in case 3. The histogenesis of these neoplasms can be assumed most likely to be mucinous metaplasia of the mesothelium or undetected heterotopic pancreatic tissue. Appropriate management is thought to be the same as for analogous ovarian neoplasms.
