  • Castleman's disease (CD) is an uncommon lymphoproliferative disorder. The disease entity is classified into 2 clinical subtypes, unicentric and multicentric type. Prevalence of lymphoid malignancy in multicentric CD (MCD) is very low. In this case, we report a case of 77 years old woman who developed high fever and swelling in both side of her neck. Neck lymph node biopsy revealed plasma cell hyperplasia. Patient's symptom was subsided after treatment with Dexamethasone. Three months later, multiple lymph node enlargement was developed in abdomen and neck area again. Repeated neck lymph node biopsy confirmed diffuse large B cell lymphoma. The patient started chemotherapy.

  • A 32-year-old female was admitted for evaluation of known mass on right suprahilar area. Chest PA showed $4{\times}3cm$ round and homogenous mass on suprahilar area. No abnormal findings were found in PFT, cytology, bacterial study, and fine needle aspiration biopsy(FNAB). On chest computed tomography, solitary mass was on right suprahilar area and no evidence of intrapulmonary metastasis or lymphnode metastasis was seen. Right upper lobectomy of lung was performed and Castleman's disease of hyaline vascular type was diagnosed based on the histologic findings of multiple and large lymphoid follicles with prominent vascular proliferation and hyalization in the central portion.

  • Castleman's disease (CD) is an uncommon benign lymphoproliferative disorder of unknown etiology. Histopathologically, it is divided into three types: hyaline-vascular, plasma cellular, and multicentric CD. The mass usually presents asymptomatically; however, it can cause non-specific symptoms such as fever and fatigue. Although CD can be found wherever lymph nodes are present, 75% of cases are reported in the mediastinum, and occurrence in the head and neck is rare. Herein, we report a rare case of CD presenting as a superficial mass in the temporal region. To the best of our knowledge, this is the first report of temporal CD in Korea involving a young patient.

  • Myocardial perfusion imaging with $^{201}Tl-chloride$ following exercise or vasodilator-induced hyperemia has been effective in detecting the presence of coronary artery disease. An increased lung uptake of thallium has been reported as a sensitive marker of severe and extensive coronary artery disease and associated with poor prognosis. Thallium has also been noted to concentrate in a variety of malignant lesions. We report 5 cases of extracardiac uptake of thallium during myocardial perfusion scan with pharmacologic vasodilation. Accumulation of thallium was found in the lesions of a breast cancer, a lung cancer, a Castleman's disease and 2 cases of thymoma. We believe that the presence of focal extracardiac uptake of thallium during myocardial perfusion scan should suggest the need for further clinical evaluation to detect the tumor and must differentiate the increased lung uptake of thallium due to left ventricular dysfunction in coronary artery disease.

  • 혈관여포양 임 파선증식 증 (angiofollicular lymph node hyperplasia)은 원인 미상의 드문 양성 질환으로서 대부분 흉곽내에 발생한다. 진단은 임상증상, 이학적 경사 그리고 X-선 촬영을 비롯한 각종 영상술에 의하며 여러 다른 질환과 감별진단이 어렵다. 대개 수술적 적출에 의한 조직학적 검색으로 확진이 된다. 조직학적으로는 두 가지로 분류되며 하나는 초자양혈관형으로서 여포내에 혈관이 증식되고 초자양화(hyalinization)가 일어나는 것이 특징이다. $90\%$가 이에 속하고 다른 하나는 형질세포형으로서 $10\%$를 차지한다. 후자는 여포간 조직내에 형질세포가 미만성으로 증식되고 신증후군, 발열, 빈혈, 적혈구침강속도 증가, 고감마글로블린혈증, 저알부민혈증 등의 변화가 있는 점이 전자와 다른 점이다. 치료는 주로 수술적 제거술에 의하며 수술로서 절제되지 못하는 것은 방사선 치료에 의하게 된다. 저자들은 경도의 흉부불쾌감과 경부 임파절 종대를 보인 61세 남자에서 전상종격동 종괴를 수술적 부분제거 후 외부 방사선 치료를 실시하여 완치된 1예를 경험하였기에 보고하는 바이다.

  • Complications of the mediastinal tumors and cysts are malignant change, infection, bleeding, local invasion and mass effect to heart, lung and other mediastinal structures. But early surgical excision and proper treatments bring patients to good clinical course and results. Therefore mediastinal tumors and cysts are surgically interesting diseases We report the analysis of the 58 cases of mediastinal tumors and cysts, experienced in the Department of Cardiothoracic Surgery of the Kosin Medical College from July 1979 to June 1989. The results were as follows ; Sex ratio of male to female to female was 1.3: 1. Range of age was from 11 to 64 years and mean age was 34.3 years. The thymomas were 14 cases[24%], the teratomas were 19 cases[33%o], the neurogenic tumors were 10 cases[17%], the cysts were 9 cases[15%], the carcinomas were 3 cases[5%], the thyroid tumor was 1 case[2%], the Castleman’s disease was 1 case[2%] and unclassified tumor was 1 case[2%]. Malignant tumors were 12 cases [21%] of the 58 cases. Most frequent symptom was chest pain and discomfort and relationship of symptom and malignancy was significant. Complete removal of tumor was performed on the 47 cases[92%] and partial excision was 3 cases[6%]. Inoperable cases were treated with anticancer chemotherapy and radiotherapy. Postoperative complications were wound infection, Homer’s syndrome, phrenic nerve palsy, mediastinal hematoma and pleurisy. There was no case of postoperative mortality and good clinical course in surgically completely resected cases.

  • Kaposi's sarcoma-associated herpesvirus (KSHV) is associated with formation of Kaposi's sarcoma, multicentric Castleman's disease, and primary effusion lymphoma. Replication and transcription activator (RTA) genes are expressed upon reactivation of KSHV, which displays a biphasic life cycle consisting of latent and lytic replication phases. RTA protein expression results in KSHV genome amplification and successive viral lytic gene expression. Transcriptional activity of viral lytic genes is regulated through epigenetic modifications. In Raji cells latently infected with Epstein-Barr virus, various modifications, such as acetylation and methylation, have been identified at specific lysine residues in histone H4 during viral reactivation, supporting the theory that expression of specific lytic genes is controlled by histone modification processes. Data obtained from chromatin immunoprecipitation and quantitative real-time PCR analyses revealed alterations in the H4K8ac and H4K20me3 levels at lytic gene promoters during reactivation. Our results indicate that H4K20me3 is associated with the maintenance of latency, while H4K8ac contributes to KSHV reactivation in infected TREx BCBL-1 RTA cells.

  • Kaposi's sarcoma-associated herpesvirus (KSHV) is one of the few human oncogenic viruses, which causes a variety of malignancies, including Kaposi's sarcoma, multicentric Castleman disease, and primary effusion lymphoma, particularly in human immunodeficiency virus patients. The currently available treatment options cannot always prevent the invasion and dissemination of this virus. In recent times, siRNA-based therapeutics are gaining prominence over conventional medications as siRNA can be designed to target almost any gene of interest. The ORF57 is a crucial regulatory protein for lytic gene expression of KSHV. Disruption of this gene translation will inevitably inhibit the replication of the virus in the host cell. Therefore, the ORF57 of KSHV could be a potential target for designing siRNA-based therapeutics. Considering both sequence preferences and target site accessibility, several online tools (i-SCORE Designer, Sfold web server) had been utilized to predict the siRNA guide strand against the ORF57. Subsequently, off-target filtration (BLAST), conservancy test (fuzznuc), and thermodynamics analysis (RNAcofold, RNAalifold, and RNA Structure web server) were also performed to select the most suitable siRNA sequences. Finally, two siRNAs were identified that passed all of the filtration phases and fulfilled the thermodynamic criteria. We hope that the siRNAs predicted in this study would be helpful for the development of new effective therapeutics against KSHV.
