AbstractAbstract PDF
BACKGROUND
The aim of study was to determine the relative frequency of malignant lymphoma according to World Health Organization (WHO) classification in Korea.
METHODS
A total of 3,998 cases diagnosed at 31 institutes between 2005 and 2006 were enrolled. Information including age, gender, pathologic diagnosis, site of involvement and immunophenotypes were obtained.
RESULTS
The relative frequency of non-Hodgkin lymphoma (NHL) and Hodgkin lymphoma (HL) was 95.4% and 4.6%, respectively. B-cell lymphomas accounted for 77.6% of all NHL, while T/natural killer (T/NK)-cell lymphomas accounted for 22.4%. The most frequent subtypes of NHL were diffuse large B-cell lymphoma (42.7%), extranodal marginal zone B-cell lymphoma (MZBCL) of mucosa-associated lymphoid tissue (19.0%), NK/T-cell lymphoma (6.3%) and peripheral T-cell lymphoma (PTCL), unspecified (6.3%), in decreasing order. The relative frequency of HL was nodular sclerosis (47.4%), mixed cellularity (30.6%), and nodular lymphocyte predominant (12.1%) subtypes. Compared with a previous study in 1998, increase in gastric MZBCL and nodular sclerosis HL, and slight decrease of follicular lymphoma, PTCL, and NK/T-cell lymphoma were observed.
CONCLUSIONS
Korea had lower rates of HL and follicular lymphoma, and higher rates of extranodal NHL, extranodal MZBCL, and NK/T-cell lymphoma of nasal type compared with Western countries. Changes in the relative frequency of lymphoma subtypes are likely ascribed to refined diagnostic criteria and a change in national health care policy.

AbstractAbstract PDF
BACKGROUND
Primary splenic vascular lesions include the tumor and the inflammatory condition. A primary splenic vascular tumor is rare but is the most common tumor of the benign primary splenic tumors.
METHODS
We describe the clinicopathological, radiological, and immunophenotypical findings of 40 cases of primary vascular lesions identified at our hospital from 1996 to 2009.
RESULTS
The patients included 18 men and 22 women, aged 12 to 74 years, with a mean of 43.3-years and median of 40-years. They comprised 14 hemangiomas (35%), 13 lymphangiomas (32.5%), three hamartomas (7.5%), three littoral cell angiomas (7.5%), three sclerosing angiomatoid nodular transformations (SANT, 7.5%) and four angiosarcomas (10%). The majority of the patients (65%) were asymptomatic. Some of the patients (32.5%) complained of abdominal pain, and 2.5% of the patients presented with fever. Metastases were identified in 75% of the patients with an angiosarcoma at the initial work-up. One angiosarcoma patient died of the disease despite adjuvant chemoradiotherapy. The radiological findings for hamartoma, littoral cell angioma, and SANT were nonspecific. Microscopically, six types of vascular lesions showed classic morphological and immunophenotypical features of their type.
CONCLUSIONS
One should be aware of rare splenic vascular lesions when radiological findings are nonspecific. Histomorphological and immunophenotypical features are helpful for the differential diagnosis.

AbstractAbstract PDF
BACKGROUND
The Hematopathology Study Group of the Korean Society of Pathologists conducted a nation-wide retrospective analysis of Korean pediatric lymphoma, to provide pathologic data on pediatric/adolescent lymphoma subtypes and features.
METHODS
All lymphoma cases of all age groups were collected during a recent 2 year-period (2005-2006) from 32 institutes in Korea. Among 3,686 lymphoma patients, 142 who were age 18 or less were classified according to the World Health Organization (WHO) classification.
RESULTS
Among 142 pediatric/adolescent lymphoma patients, Hodgkin lymphoma accounted for 21 (14.8%) and non-Hodgkin lymphoma (NHL) for 121 (85.2%). Hodgkin lymphoma appears to be more common in the pediatric/adolescent age group than in the all-ages group (14.8% vs 4.4%). T- and natural killer cell-NHL was more common in the pediatric/adolescent age group than in the all ages group (46.3% vs 22%). The majority of Korean pediatric/adolescent NHL cases was composed of Burkitt lymphoma, T- or B-lymphoblastic lymphoma, anaplastic large-cell lymphoma, and diffuse large B-cell lymphoma. For lymphoma patients under the age of 6 years, most had B-lymphoblastic or Burkitt lymphoma, which commonly presented at extranodal sites.
CONCLUSIONS
The distribution of lymphoma subtypes in the pediatric/adolescent age group is quite different from the distribution of adults, but it was quite similar to distribution in Western countries.

AbstractAbstract PDF
Low-grade adenocarcinomas that primarily arise within the sinonasal tract are uncommon tumors. We report here on three cases of primary sinonasal low-grade adenocarcinomas. The patients were 2 females and 1 male with ages of 48, 57 and 64, respectively. Microscopically, the tumors had a well developed tubulopapillary growth pattern that consisted of columnar or pseudostratified cells with eosinophilic cytoplasm, round to oval nuclei and rare mitotic activity. On immunohistochemistry, the tumor cells were strongly positive for cytokeratin 7, but they were negative for cytokeratin 20, CDX-2 and p53. The Ki-67 labeling index was very low (mean: 1.9%). Two patients developed recurrent tumors at the primary site after the initial surgery, but all the patients are presently alive without metastasis 6 years 8 months, 8 years 8 months, and 11 months after the initial diagnosis. When considering the progress of these tumors, we think that it's important to understand the pathology of this entity to avoid underdiagnosis because a complete excision is required for effective treatment.

AbstractAbstract 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.

AbstractAbstract PDF
Plasmablastic lymphoma(PBL) is a recently described aggressive B-cell neoplasm, which usually manifests as a localized disease of the oral mucosa in individuals infected with human immunodeficiency virus(HIV). Recently, we encountered a case of plasmablastic lymphoma manifesting in the left maxillary sinus and cervical lymph node of a previously healthy HIV-negative man, 48 years of age. we conducted a fine-needle aspiration smear of the cervical lymph node, and this was found to be highly cellular with numerous large cells exhibiting eccentrically positioned nuclei, prominent nucleoli, and moderate quantities of basophilic cytoplasm. A biopsy of the mass in the maxillary sinus evidenced diffuse growth of similar plasmablastic cells. These tumor cells were negative for the leukocyte common antigens, CD20, CD3, CD30, and EMA. However, the cells tested positive for CD79a and CD138/syndecan-1. The tumor cells also exhibited L-light-chain restriction. The Ki-67 proliferation index was measured at almost 100%. The patient was diagnosed with plasmablastic lymphoma. After three cycles of combination chemotherapy and radiotherapy, the patient went into complete remission, and currently remains in this state.

AbstractAbstract
Synchronous occurrence of triple distinct malignant tumors in the same patient is very rare. We report a unique case of a triple cancer occurring in a 70-year-old Korean woman with synchronous signet ring cell carcinoma of the stomach, renal cell carcinoma of the conventional type of the left kidney, and invasive ductal adenocarcinoma and intraductal papillary carcinoma of the pancreas. All three cancers were successfully resected simultaneously by total gastrectomy, nephrectomy, and partial pancreatectomy with corresponding lymphadenectomies. This patient tolerated these surgical procedures well and led a normal healthy life during the 18 months of follow-up. In summary, a successful resection of synchronous triple cancers which has never been previously reported in such combination, is described.

BACKGROUND
The pathogenesis of transition from viral myocarditis to dilated cardiomyopathy is elusive, although the incidence of dilated cardiomyopathy in human is increasing.
METHODS
To clarify the role of the tissue inhibitor of matrix metaloproteinase-2 (TIMP-2) in this event, we performed immunohistochemistry, immunoblotting and immunoassay of matrix metalloproteinase-9 (MMP-9) and TIMP-2 in the serum and heart tissue of mice, which were inoculated with 4000 plaque-forming units of coxsackie B virus.
RESULTS
The MMP-9 was expressed in damaged cardiomyocytes, and the TIMP-2 was expressed in mainly interstitial connective tissue between cardiac muscle bundles by immunohistochemistry. The level of serum MMP-9 was higher in the complicated than non-complicated group (p<0.001), but the level of TIMP-2 was much lower in complicated than non-complicated group (p<0.05). These findings were similar to the results of immunohistochemistry and immunoblotting in tissues.
CONCLUSIONS
These results suggest that an imbalance in the level of MMP-9 and its inhibitor might activate cardiac complication in viral myocarditis.

AbstractAbstract PDF
Phospholipase C (PLC) plays a role in ligand-mediated signal transduction for cellular activity such as proliferation and differentiation. A recent observation that PLC- gamma1 is highly expressed in some kinds of human cancer tissue supports the view that PLC-gamma1 may be involved in proliferation and carcinogenesis. PLC-gamma2 is known to be involved in B cell differentiation and maturation. However, there have been few studies about the expressions of PLC-gamma1 and gamma2 in human lymphoid malignancy. In the present study, we examined the contents of PLC-gamma1 and gamma2 in 10 cases of B cell, 10 cases of T cell non-Hodgkin's lymphoma and 5 cases of Hodgkin's lymphoma to find out whether these enzymes play any role in the carcinogenesis by immunohistochemistry and immunoprecipitation. Immunoprecipitation analysis revealed that in contrast to increased expression of PLC-gamma2 only in B cell lymphoma, a considerably higher level of PLC-gamma1 was detected in both B and T cell lymphoma. Immunohistochemical finding confirmed this observation. PLC-gamma1 and PLC-gamma2 were expressed in the cytoplasm of most tumor cells. PLC-gamma2 was also expressed in mature B cells, while PLC-gamma1 was not expressed in reactive non-tumor cells. These results suggest that PLC-gamma1 mediated signal transduction implicates a significant role in the carcinogenesis of all types of lymphoid tissue, and PLC-gamma2 may play a role in the carcinogenesis of B cell lymphoma as well as B cell differentiation.

AbstractAbstract PDF
Benign and malignant papillary neoplasms of the breast may be difficult to distinguish in both cytologic and histologic preparations. To define the cytologic features of benign and malignant papillary lesions, we retrospectively reviewed 18 cases of fine needle aspirates from histologically confirmed cases of papilloma or papillary carcinoma of the breast. This study included 3 intraductal papillary carci nomas, 3 invasive papillary carcinomas, and 12 intraductal papillomas. All cases were evaluated for presence or absence of papillary fragments, bloody background, apocrine metaplasia, macrophages, and degree of cellularity, atypia, and single isolated columnar epithelial cells. Papillary fragments were present in all cases. The background of the smear was bloody in all 6 carcinomas, but in only 7 out of 12 papillomas. Markedly increased cellularity was present in 4 carcinomas(67%) and 7 papillomas(58%). Single cells were present in 5 carcinomas(83%) and 8 papil lomas(67%). The majority of papillomas and papillary carcinomas had mild to moderate atypia, and severe atypia was noted in one case of intraductal papillary carcinoma and one case of invasive papillary carcinoma. Apocrine metaplasia was absent in all cases of papillary carcinomas, but present in 8 papillomas(67%). Macrophages were noted in 4 carcinomas and were present in all cases of papillomas. The constellation of severe atypia, bloody background, absence of apocrine metaplasia and/or macrophages were features to favor carcinoma. Malignant lesions tended to show higher cellularity and more single isolated cells. The cytologic features mentioned above would be helpful to distinguish benign from malignant papillary lesions of the breast. However, because of overlapping of cytologic features, surgical excision should be warranted in all cases of papillary lesions of the breast to further characterize the tumor.

AbstractAbstract
LMP (latent membrane protein)-1 protein is one of the Epstein-Barr viral proteins and it is the most crucial one for the transforming activity. It is known to show considerable variation in its nucleic acid sequence and some biologic difference is reported to be associated with the variation. Twenty four cases of the EBV-associated Hodgkin's disease cases were searched for the 30-bp deletion within the C terminal intracytoplasmic domain of LMP-1 oncogene, one of the well-known genetic variation, by PCR and Southern blot using selected sets of primers and probes. The strain of the virus was also determined with PCR. Each case was positive both on LMP-1 immunostaining and in situ hybridization for EBER (Epstein-Barr encoded RNA). Deletion within LMP-1 oncogene was identified in 22 cases (92%), of which 5 cases showed wild form as well as a deleted form of LMP-1 at the same specimens. In seven cases showing the non-deleted form, pure or mixed with a deleted form, the distribution of sex and age was similar to that of the deleted form-only-group, but there was a slight tendency for a higher stage at presentation (4 of the 7 cases presented with stage IV). Those seven cases comprised of 4 cases of nodular sclerosis (NS), 2 cases of mixed cellularity (MC) and a case of lymphocyte depletion subtype while there were 9 and 12 cases of NS and MC among all the examined cases, respectively. Two cases with both a deleted form and the non-deleted form of LMP-1 showed type I and II strain of the virus while all the others contained only type of the. In conclusion, the rate of deletion in LMP-1 oncogene in our series was higher than that reported in western countries and there was a slight tendency for higher stages in cases detecting mixed deleted and non-deleted forms of LMP-1 than in cases a of deleted from of LMP-1.

AbstractAbstract PDF
Although the success of the Papanicolaou test as a screening tool of cervical cancer is evident, there still exists 2-5% of discrepancy rate by both human and machine. To improve the qualilty of cervico-vaginal cytology, the authors compared cervicovaginal smear with cervical biopsy diagnoses, and analysed the causes of discrepancies. Among 30,922 cervicovaginal smears from June 1996 to April 1997 at our hospital, there were 271 cases of cervicovaginal smear with subsequent cervical punch or LEEP cone biopsies within several months. The biopsies and smears from a total of 98 discordant cases were reviewed. The discrepancy was attributed to sampling errors in 43 cases(43.9%), and to cytologic diagnosis in 49 cases(50.0%). Among these, 43 cases were interpretative errors(categories A;19, B;16 and C;8), whereas six cases were screening errors(categories B;2 and C;4). Among cervical biopsy cases, errors were present in four. As for 10% random rescreening, cytote chnologists reviewed 3,196 of 30,922 smears during the same period. There were 43 cases of screening error(categories A;27, B;16). Cytologic/histologic correlation was superior to 10% random rescreening of negative cases. The most effective method for quality improvement in cervicovaginal cytology was to implement both quality control(rescreening) and quality assurance(cytologic/histologic correlation) programs.

AbstractAbstract PDF
Fine needle aspiration cytology(FNAC) has become a popular method for the diagnosis of a wide variety of both superficial and deep-seated lesions. However, there are few reports about the potential of FNAC for the diagnosis of intraoral lesions. We experienced 44 FNACs from intraoral lesions at Asan Medical Center: 22 from the palate, 6 from the tongue, 5 from the parapharyngeal space, 5 from the lip, 2 from the floor of mouth, 1 from the buccal mucosa, and 3 from other intraoral sites. Histological confirmation was obtained in 32 cases and we analyzed 27 cases excluding 5 cases of inadequate aspirates. Diagnosis was specifically made in 19 of 27 cases(70%) including 1 mucoepidermoid carcinoma, 1 undifferentiated carcinoma, 1 chordoma, 9 pleomorphic adenomas, 1 neurofibroma, and 6 benign lesions. There were three false negative cases(sensitivity, 62.5%) and no false positive cases(specificity, 100%): Two cases diagnosed as "cystic lesion" were confirmed to be mucoepidermoid carcinomas and a case diagnosed as pleomorphic adenoma was proved to be adenoid cystic carcinoma. The results of our study suggest that FNAC is a useful technique in the diagnosis of intraoral lesion.

AbstractAbstract PDF
Heart transplantation was first performed in 1967. It is now regarded as a well-established treatment modality for end-stage cardiac diseases. Once the transplantation is performed, endomyocardial biopsy(EMB) is the examination of choice in monitoring the transplanted heart. We analyzed the pathological findings of follow-up EMB of 6 heart transplant patients. All patients have been suffered from severe heart failure. Four patients were adult male and two were adult females. All the hearts, except for one, displayed characteristic features of dilated cardiomyopathy. The remaining heart was diagnosed as having giant cell myocarditis. Post-transplantion EMBs were performed according to the protocol and standard cardiac biopsy grading of ISHT (1990). The standards were applied for grading of cellular rejection. In five patients, there were one or two episodes of biopsy proven acute rejection, grade II or IIIA without any clinical symptoms of rejection. Immediate "pulse therapy" was performed and follow-up biopsies were done. All episodes of rejection were cleared in subsequent biopsies. All patients are doing well without evidence of cardiac problem. The postoperative monitoring of acute rejection is critical since clinical signs of rejection are usually absent. At present, EMB is regarded as the most reliable method for diagnosis and grading of acute rejection and is an efficient guide to the monitoring of the cardiac recipients. Our experience of post-transplantation EMB corresponds with previously published reports.
