Ki-1 positive anaplastic large cell lymphoma is a newly described high-grade lymphoma and is defined by histopathological and immunologic criteria. We experienced a case of systemically involving Ki-1 positive anaplastic large cell lymphoma in a 44 year-old female which initially manifested as pleural effusion. Abdominopelvic CT scan showed the evidence of marked lymphadenopathy in retroperitoneal and both external and inguinal lymph nodes. On cytologic examination of pleural fluid, tumor cells revealed pleomorphic large isolated cells with prominent nucleoli and abundant cytoplasms. The nuclei were large with irregular profiles including some deep invaginations. Also, occasional multilobed/multinucleated and binucleated nuclei were seen. Immunohistochemical examination was performed to differentiate from the undifferentiated adenocarcinoma, Hodgkin's disease, non-Hodgkin's lymphoma and malignant histiocytosis. The neoplastic cells were positive for leukocyte common antigen, CD3, CD30(Ki-1) but negative for cytokeratin, epithelial membrane antigen, and CD15. A histologic diagnosis of Ki-1 positive anaplastic lymphoma was made by biopsies of the inguinal lymph node, polypoid lesions of the stomach and cecum.

흉막의 종괴는 다양한 양성과 악성 종양이 있고 종양은 아니지만 종양 같은 질환들에 의해 발생한다. 일차 흉막 종양에는 고립섬유종양, 악성중피종, 그리고 원발성 흉막 비호지킨 림프종이 있다. 흉막에 발생하는 가장 흔한 종양은 전이성 질환이며, 림프종, 백혈병, 다발성 골수종 등의 혈액 종양을 가진 환자에서 드물게 나타난다. 흉수는 주로 흉막의 악성 질환과 연관이 있다. 드물지만 흉막 종양이 만성 농흉에서 생길 수 있으며, 그중 가장 흔한 것은 비호지킨 림프종이다(농흉과 연관된 림프종). 종양이 아닌 흉막 종괴로는 다양한 양성 질환에서 보일 수 있으며, 여기에는 결핵, 석면 흉막판, 그리고 흉막 유리체가 포함된다. 이 임상화보에서 저자들은 흉막의 다양한 양성과 악성 종양 및 종양성 질환들에 대한 특징적인 전산화단층촬영 소견에 대해 알아보고자 한다.

I, II기 원방성 위장관 임파종 환자 38명의 수술후 방사선 치료 결과를 분석하였다. 방사선 치료 중 6예의 원격전이가 관찰되었고, 방사선 치료 전 병소의 크기에 따른 치료실패율은 5cm 미만에서 $31\%$, 5cm 이상에서 $75\%$로 유의한 차이가 있었다(p<0.05). 방사선 치료를 계획대로 받은 28예서 5년 생존율은 $69.2\%$였고, 그중 병소의 크기가 5cm 미만인 경우는 $72\%$였다. 병소의 크기에 따른 5년 무병생존율에도 차이가 있어 5cm 미만인 경우엔 $71\%$, 5cm 이상인 경우엔 $25\%$였다(p<0.05). 반면에 병기, 병리학적 유형 및 원발장기 등에 따른 생존율의 차이는 유의하지 않았다. 따라서 방사선 치료 전 병소 크기가 5cm 미만일 경우는 완치가 가능하나, 5cm 이상으로 클 경우에는 항암화학요법의 병용이 시도될 수 있겠다.

Objective: To investigate the relationship between plasma EBV-DNA concentration and clinicopathologic features of Hodgkin's lymphoma cases. Methods: At first, the positive rate of plasma EBV-DNA was determined with a nested-PCR method using 45 specimens from Uygur HL patients, as well as 110 healthy people sampled as normal controls. Secondly, using fluorescent quantitative nested-PCR, EBV viral load was assessed in the EBV-DNA positive plasma samples. Then, relationships between plasma EBV viral load and clinicopathologic features of HL patients were analyzed. Results: The positive rate of plasma EBV-DNA of HL patients was significantly higher than that of normal controls (53.3% vs 26.4%, P=0.001). There was no significant difference about plasma EBV viral load between EBV-associated HL and EBV-DNA positive normal people (P=0.490). Looking at patients' characteristics, plasma EBV viral load in 10-20 years EBV-associated HL was higher than in EBV cases which were less than 10 years or more than 35 years (P=0.025). Furthermore, in EBV-associated HL, concentration of plasma EBV-DNA was significantly higher in advanced stage disease (stages III-IV; P=0.013), and with B-symptoms (P=0.020). Conclusion: EBV-DNA levels were associated with part of clinicopathologic features of cases. It was of practical use to screen HL. Further etiological studies appear warranted.

Background: With advances in diagnostics and treatment approaches, patients with Hodgkin's lymphoma (HL) in developed countries can nowadays expect to have excellent outcomes. However, information about the characteristics and outcomes in the developing world is very scarce, and this is important given the fact that there are several reports about differences of disease characteristics depending on geographic location and the development level of the country. Materials and Methods: In this retrospective study we assessed the features of 36 adult (${\geq}18$ years old) patients with HL and their diagnosis and treatment and outcomes in the Clinic of Chemotherapy of Muratsan University Hospital of Yerevan State Medical University, Armenia, between 2008-2014. Results: All patients had classic HL and among them 19 (53%) had nodular sclerosis subtype, 8 (22%) mixed cellularity and 9 (25%) lymphocyte-rich. 16 (44.5%) patients were at stage II, 13 (36%) stage III and 7 (19.5%) stage IV. Median follow-up time was 24.5 months (range 1-71 months) and during the whole follow-up period only two relapses (early) were documented and there were no deaths. Twenty-three (64%) patients received a BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone) regimen, and 13 (36%) ABVD (doxorubicin, bleomycin, vinblastine and dacarbazine) regimen. A total of 25 (69.5%) patients received radiation in addition to chemotherapy. Conclusions: Although the number of patients involved in the study is small and the median follow-up time was just two years, this retrospective study shows that treatment of HL can be successfully organized in a resource-limited setting.

Herein we report the case of a 71-year-old woman who complained of fatigue and enlarged right axillary lymph nodes for 18 months. At her first visit, her chest X-ray showed diffuse nodular opacities in both lung fields. Initial excisional biopsy of the axillary lymph nodes showed granulomatous lesions and acid fast bacilli were seen on Ziehl-Neelsen staining. However, even after 15 months of anti-tuberculosis (TB) medication, her right axillary lymph nodes were enlarged. We re-performed an excisional biopsy of the nodes, which showed Hodgkin's lymphoma (HL). A retrograde review of the biopsy before anti-tuberculous medication, revealed HL coexisting with TB. HL and TB cause difficulties in differential diagnosis due to similarities in clinical course, imaging procedures and histopathological analysis of the involved tissue. Therefore, it is important to consider the possibility of concurrent HL and TB when patients who undergo treatment for TB or chemotherapy for lymphoma complain of persistent systemic symptoms or enlarged lymph nodes.

후두에 생긴 원발성 임파종은 성문상부에 잘 생기며 일차치료로 방사친치료가 이용되나 후두외로 퍼진 경우는 항암화학치료와의 병용요법이 필요하다. 후두악성임파종의 전이나 재발여부에 대해 장기적 추적 관찰이 중요함을 문헌고찰과 함께 보고하는 바이다.

Purpose: The aim of this article is to review a group of lesions associated with periodontal ligament (PDL) widening. Materials and Methods: An electronic search was performed using specialized databases such as Google Scholar, PubMed, PubMed Central, Science Direct, and Scopus to find relevant studies by using keywords such as "periodontium", "periodontal ligament", "periodontal ligament space", "widened periodontal ligament", and "periodontal ligament widening". Results: Out of nearly 200 articles, about 60 were broadly relevant to the topic. Ultimately, 47 articles closely related to the topic of interest were reviewed. When the relevant data were compiled, the following 10 entities were identified: occlusal/orthodontic trauma, periodontal disease/periodontitis, pulpo-periapical lesions, osteosarcoma, chondrosarcoma, non-Hodgkin lymphoma, progressive systemic sclerosis, radiation-induced bone defect, bisphosphonate-related osteonecrosis, and osteomyelitis. Conclusion: Although PDL widening may be encountered by many dentists during their routine daily procedures, the clinician should consider some serious related conditions as well.

Two cases of primary malignant lymphoma of the brain and six cases of secondary CNS lymphoma seen at Yonsei cancer center, radiotherapy department for recent 4 years are presented. Primary lymphomas revealed single tumor mass on corpus callosum area and secondary lymphoma were intracranial (3 cases) or leptomeningeal type (3 cases). Histology of primary lymphoma were reticulum cell sarcoma and secondary lymphomas were either diffuse histiocytic or diffuse poorly differentiated lymphocytic lymphoma. All patients showed good response to radiation. Two patients with primary CNS lymphoma and two of six secondary CNS lymphoma are alive after radiotherapy (34, 31, 26, 12 months). But the prognosis of secondary CNS lymphoma is grave, because of progressive systemic disease. Incidence, risk factors, diagnosis and therapeutic management of CNS involvement are also discussed.
