Background
Pokemon is an oncogenic transcription regulator that plays a critical role in cellular differentiation. Although it has been found to be overexpressed in several types of cancer involving different organs, its role in thyroid gland has yet to be reported. The objective of this study was to evaluate the expression of Pokemon in papillary thyroid carcinoma (PTC) based on clinicopathological parameters.
Methods
Tissue microarray samples derived from patients with PTC or benign thyroid disease were used to evaluate Pokemon expression based on immunohistochemical analysis. Correlations of its expression with various clinicopathological parameters were then analyzed.
Results
Pokemon expression was observed in 22.0% of thyroid follicular cells from the normal group, 44.0% from the group with benign thyroid diseases, and 92.1% from the group with PTC (p < .001). The intensity of Pokemon expression was markedly higher in the PTC group. Pokemon expression level and PTC tumor size showed an inverse correlation. T1a tumors showed strong expression levels of Pokemon. However, larger tumors showed weak expression (p = .006).
Conclusions
Pokemon expression is associated with tumorigenesis of PTC, with expression showing an inverse correlation with PTC tumor size. This might be related to the negative regulation of aerobic glycolysis by Pokemon.

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

Heterotopic gastrointestinal cysts are rarely found in the oral cavity. Most of these cysts are lined with gastric mucosa and involve the tongue. There have been no reported heterotopic intestinal cysts of the submandibular gland that are completely lined with colonic mucosa. An 8-year-old girl presented with an enlarging swelling in the left submandibular area, and a 4-cm unilocular cyst was fully excised. The cyst was completely lined with colonic mucosa that was surrounded by smooth muscle layer, and the lining cells were positive for CDX-2, an intestinal marker, indicating a high degree of differentiation. The pathogenesis remains unclear, but it may be related to the misplacement of embryonic rests within the oral cavity during early fetal development. Although heterotopic intestinal cysts rarely occur in the submandibular gland, they should be considered in the differential diagnosis of facial swellings in the pediatric population.

Abstract PDF: Background
Understanding the biologic behavior of a tumor is a prerequisite for tumor registration code assignment. The aim of this report was to propose appropriate behavior codes of the International Classification of Disease Oncology 3 (ICD-O3) to rare, yet pathologically interesting hematopoietic and soft tissue tumors.
Methods
The Study Group for Hematopathology, the Bone and Soft Tissue Pathology Study Group, and the Cancer Registration Committee prepared the questionnaire containing provisional behavior codes of selected diseases.
Results
In situ lesions of mantle cell and follicular lymphomas, dendritic cell tumors, and neoplasms with perivascular epithelioid cell differentiation (PEComa), not otherwise specified were classified as malignant (-/3). The fibromatosis group, with the exception of lipofibromatosis, was proposed as benign (-/0). Lipofibromatosis and several diseases that belong to the PEComa group were proposed as uncertain malignant potential (-/1). For the hematologic and soft tissue tumors, 274 and 288 members of the Korean Society of Pathologists, respectively, provided opinions through questionnaire, and most responders showed agreement with the provisional behavior code proposed.
Conclusions
The determination of behavior codes for the rare diseases described in this study, especially those of the PEComa group or malignant lymphoma, could be viewed as impractical and premature, but this study provides the basis for future research on this topic.

Abstract PDF

BACKGROUND
The Korean Bone and Soft Tissue Pathology Study Group of the Korean Society of Pathologists conducted a nationwide retrospective analysis of soft tissue sarcoma (STS) to provide the clinicopathologic characteristics of STS within the population of the Republic of Korea.
METHODS
The cases of STS were collected during a 7-year period (2001-2007) from 19 institutes in Korea. All cases were classified according to the histologic criteria proposed by the World Health Organization. Clinicopathologic data were reviewed.
RESULTS
Data from 722 patients (median age, 50 years) were collected. Data showed a slight male predominance. The most frequent types of STS in decreasing order were liposarcoma, malignant fibrous histiocytoma, leiomyosarcoma, and synovial sarcoma. STS occurred throughout the body, although approximately half (47.8%) were located in the extremities. The majority of STS was histologically classified as high grade with a large tumor size (>5 cm). The overall survival rate for the patients was 76.3% (median follow-up time, 26 months; range, 1 to 89 months). Histologic grade, tumor size, American Joint Committee on Cancer stage, tumor site, and resection status were prognostic. Significant independent adverse prognostic factors were large tumor size (>5 cm) and tumor site other than extremities.
CONCLUSIONS
We reported the distribution and characteristics of STS in the Republic of Korea.

Abstract PDF

Anaplastic thyroid carcinoma (ATC) is an uncommon aggressive malignant tumor, and the osteoclastic variant of ATC is extremely rare. We report here on the fine needle aspiration cytology of the osteoclastic variant of ATC in an 83-year-old woman. The smear was composed of many oval to slightly elongated undifferentiated mononuclear cells admixed with multinucleated osteoclast-like giant cells. The mononuclear tumor cells revealed inconspicuous nuclear pleomorphism and the nuclei were characterized by vesicular chromatin and an indented or lobulated nuclear membrane with conspicuous nuclear grooves. A few epithelial clusters suggestive of a papillary carcinoma component were also observed. Making the proper cytological diagnosis of the osteoclastic variant of ATC is helpful to determine the proper treatment modality for these patients.

Abstract PDF

BACKGROUND
The aim of this study was to evaluate differences in cytologic findings between conventional preparation (CP) and SurePath(TM) liquid-based preparation (LBP) in thyroid fine needle aspiration (FNA).
METHODS
We analyzed cytological features on a total of 182 thyroid FNAs (83 CP and 99 LBP) that were histologically confirmed as nodular hyperplasia (NH) or papillary carcinoma (PAC).
RESULTS
LBP was superior in cellular preservation and cellularity than CP. Interestingly, in LBP, cellularity of NH was similarly high compared to that of PAC. The three-dimensional pattern was more prominent in LBP than in CP. The presence of follicle structures was more frequently found in LBP than in CP in the PAC group. Dispersed single cells in the background were more prominent in LBP than in CP. In the PAC group, contrast of the nuclear membrane was more distinctive in CP than in LBP.
CONCLUSIONS
In thyroid FNA, LBP is better for cellular preservation, cellularity, background and nuclear detail than CP. However, some features in LBP such as high cellularity in NH, prominent dispersed single cells, and frequent follicle patterns were unfamiliar findings in CP. Hence, we should be aware of these cytomorphologic features in LBP to make a proper diagnosis.

Abstract PDF

Pulmonary epithelioid hemangioendothelioma (PEH) is a rare vascular tumor of low to intermediate malignant potential, and PEH can mimic other more common tumor entities pathologically as well as clinically. Compared to its well-recognized histological features, its cytological findings have been reported rarely to be plasmacytoid or epithelioid cells with abundant dense or finely granular cytoplasm, cytoplasmic vacuoles, round nuclei and prominent nucleoli.We report here on the fine needle aspiration cytologic findings of a 38-year-old woman with EH of the lung, that showed in addition to its classical cytomorphology, a somewhat peculiar cytologic finding such as big twig-like rosettoid structures with prominent hyalinized stroma. This tumor was histologically and immunohistochemically proven to be PEH by primary antibodies for CD31, CD34 and vimentin. We emphasize that the accuracy of making a cytologic diagnosis of this rare tumor can be increased by recognizing the peculiar cytologic finding that we report on here.

Abstract PDF: Kuttner tumor is a relatively uncommon benign tumor-like lesion of the salivary gland that clinically mimics neoplasm because of its presentation as a hard mass. It is also known as chronic sclerosing sialadenitis or cirrhosis of the submandibular gland. We present here the aspiration cytological findings of a case of Kuttner tumor in a 58-year old woman. The aspiration specimen of this lesion showed numerous lymphoid cells that were similar to lymph node aspirates, with several scattered benign ductal cells and eosinophilic fibrous tissue. The lymphoid cells were composed of mature bland lymphocytes and follicular center cells. Any acinar cells were not identified. The excised mass was ill-demarcated, hard and fibrotic, and it histologically exhibited an intense lymphocytic infiltration with irregular lymphoid follicle formation, dense periductal and stromal sclerosis, and loss of acini. No evidence of neoplasm or sialolithiasis was discovered, and this led to the diagnosis of Kuttner tumor.

Abstract PDF

BACKGROUND
The aim of this study was to confirm the usefulness of cervicovaginal smears in the screening of squamous cell neoplasms of the uterine cervix by comparative analysis between the cytologic diagnosis of cervicovaginal smears and the histologic diagnosis of tissue specimens.
METHODS
We selected 743 patients who had both cervicovaginal smears and histologic evaluations of the uterine cervix by colposcopic biopsy, conization, or hysterectomy at the Kangbuk Samsung Medical Center between January 2005 and December 2007.
RESULTS
The accuracy rate of cervicovaginal smears and histologic diagnoses was 93.0% (691/743) and showed a high correspondence (kappa value, 0.770, p-value, 0.000). The false-negative and false-positive rates were 0.5% (6/484) and 17.8% (46/259), respectively. The sampling and interpretation errors were identified in four and two cases of six false-negative cases and 29 and 17 cases of 46 false-positive cases, respectively. In screening high grade squamous cell neoplasms, there were no false-negative cases and only one false-positive case which resulted from sampling error. The false-negative rate of cervicovaginal smears and the false-positive rate in high-grade squamous cell neoplsams were very low.
CONCLUSIONS
The cervicovaginal smear is a powerful tool for screening of cervical squamous cell neoplasms.

Abstract PDF: BACKGROUND
Fascin is associated with motility in various transformed cells. Overexpression of fascin is known to aid in the progression of some cancers and is associated with a poor prognosis. E-cadherin is a major protein of epithelial cells and its expression is involved in the regulation of cell proliferation and differentiation. The aim of this study was to determine the expression pattern for fascin and E-cadherin and how it is related to the prognostic factors for renal cell carcinoma (RCC).
METHODS
The expression of fascin and E-cadherin was evaluated in 208 RCCs including 175 clear cell, 20 papillary, and 9 chromophobe types using tissue array analysis.
RESULTS
The expression of fascin increased as the tumor stage (p=0.00) and Fuhrman grade (p=0.00) increased. A high positive rate of expression for fascin was observed in cases with sarcomatoid changes (p=0.27). E-cadherin expression was seen in the distal tubules and collecting ducts of normal kidneys with a membranous pattern. The positive rate of expression for E-cadherin increased as the Fuhrman grade increased (1, 0%; 2, 23.2%; 3, 34.9%; and 4, 53.8%, p=0.00). An inverse correlation in RCCs was observed in the expression of fascin and E-cadherin (p=0.026, r=-0.158).
CONCLUSIONS
In patients with RCC, the increased expression of fascin and E-cadherin was positively correlated to poor prognostic factors such as a higher Fuhrman nuclear grade and advanced pTNM stage.

Abstract PDF

Fine-needle aspiration cytology (FNAC) cannot differentiate follicular adenoma from follicular carcinoma since this distinction can only be based on the presence of capsular or vascular invasion, and this cannot be detected on a cytologic smear. The goal of this study was to define the diagnostic cytologic findings of follicular neoplasm and the possibility of diagnosing follicular neoplasm by performing FNAC. The cases of histologically diagnosed follicular adenoma and follicular carcinoma on the thyroidectomy specimens were retrieved. Among them, the cases with preoperative FNAC that was done within 3 months of the operation were finally selected. Then we reviewed the FNAC and histologic slides of 19 cases: 9 follicular adenomas and 10 follicular carcinomas. Our results suggest that for cases of follicular neoplasm, the aspirates show high or abundant cellularity, frequent follicle formation and occasional cellular atypism of the follicular cells. However, the atypism is more pronounced and more frequently noticed in the cases of follicular carcinoma, which reveals more higher anisocytosis (7/10, 70%), nuclear pleomorphism (9/10, 90%), coarse clumping of chromatin (8/10, 80%) and cellular overlapping (8/10, 80%).

Abstract PDF: Intestinal metaplasia (IM) have long been thought to play a role in the pathogenesis of gastric intestinal adenocarcinoma, but not in that of diffuse cancer. We studied 20 normal gastric mucosa, 90 IM, 39 atypia (dysplasia or adenoma), and 51 adenocarcinoma to evaluate the expression of p53, erb B2, and H-ras p21 proteins and to assess the correlation with IM (esp. type III IM, revealing positive HID-AB/PAS for sulfomucin). Positive rate of HID-AB staining revealed an increased trend in comparison between IM, atypia and adenocarcinoma. It was the highest in mucinous carcinoma, but it was not correlated with positive oncoprotein expressions. Positive rates of oncoproteins revealed increased trends in comparison between IM, dysplasia or adenoma and adenocarcinoma in c-erb B2 and p53 (P<0.01). The positive rates were highest in intestinal adenocarcinoma (50.0% and 54.2%, respectively). Rates were lowest in biopsy tissue of IM (4.4% and 8.7%, respectively). The expression of H-ras p21 was not significant in gastric carcinogenesis. There was no significant correlation between oncoproteins and other clinical parameters, such as depth of invasion, differentiation, size and nodal metastasis of the tumors. Therefore, we suggest that p53 and erb B2 may play a role in the carcinogenesis of gastric intestinal adenocarcinoma.

Abstract PDF: Injuries from sea urchins are induced by from penetration of the calcareous spines into the skin. Apart from the transient episode of excruciating pain, there is usually no residual disability. Complications arise, however, when spines are embedded over bony prominences, or within joints. Two cases are reported with injury and protracted disability of fingers resulting from contact with the purple sea urchin, Anthocidaris crassispina, a common echinoderm inhabitant of the Korean east coast. After a latent period of several months in both cases, Case 1 presented as caseating granulomas in the synovium and case 2 exhibited as the usual soft tissue nonsynovial foreign body and noncaseating granulomas. There appears to be a paucity of published data regarding the effects of puncture wounds caused by the spines of this animal. The granulomas have appeared after a latent interval of several months in a proportion of the sufferers, suggests a delayed hyperserisitivity reaction similar to that produced by Mycobacterium species.
