  • Background: Primary malignant lymphoma of the parotid gland is a rare disease and defined as any malignant lymphoma that first manifests in the parotid gland, regardless of the subsequent stage of the diseases, whether it arises in the parenchyma or intraglandular lymph nodes. This study was performed to review the clinicopathological characteristics of primary parotid lymphoma and identify its optimal treatment modality. Materials and Methods: Six cases with parotid mass as first presentation of malignant lymphoma between 1988 and 2000, were studied on the basis of clinical features, diagnostic tools, treatment modality, treatment outcomes, and clinical stage by Ann Arbor Criteria. All were microscopically reevaluated and classified by NCI working formulation. Results: All patients were males and mean age was 36.7 years (2-66 years). Rapid growing non-tender mass was presented in all the cases and cervical lymphnodes were palpated in 4 cases. However, there was not any evidence of concurrent autoimmune disease such as Sjogren's syndrom or Rheumatoid arthritis. One case was confirmed by surgical specimen after superficial parotidectomy, 2 by excisional biopsy, and 3 by incisional biopsy. The stage of disease by NCI working formulation was IE in 1 patient, IIE in 4 and IV in 1. All were classified into non-Hodgkin' lymphoma, of which there were 5 cases of B-cell type and 1 case of T-cell type. There were 3 diffuse large cell lymphomas, 1 Burkitt lymphoma, 1 MALT lymphoma and 1 T-lymphoblastic lymphoma. Three cases were treated by chemotherapy only, 2 by radiotherapy only and 1 by chemo-radiotherapy. One case with Burkitt lymphoma was died from the disease and one case was lost to follow-up. The others are alive with no evidence of recurrence. Conclusions: Although primary parotid lymphoma is rare and difficult to diagnose preoperatively, most were detected in early stage and showed a relatively good response to the chemotherapy or radiotherapy like other types of extranodal malignant lymphoma.

  • Primary non-Hodgkin's lymphoma of the lung is rare among extranodal lymphomas. The most common form is low grade B-cell type originated from the mucosa-associated lymphoid tissue (MALT) of the lung and primary peripheral T cell lymphoma of the lung is extremely rare. We recently experienced a case of fine needle aspiration cytology of primary peripheral T cell lymphoma of the lung in a 39-year-old male patient. The cytologic smears revealed some sheets of reactive epithelial cells, epithelioid histiocytes, and numerous polymorphous population of lymphoid cells composed of small and intermediate sized lymphoid cells and mature lymphocytes. Lymphoid cells were slightly larger than normal mature lymphocytes and showed significant irregularity of nuclear membrane. The internal nuclear structure was marked by chromatin clumping, clear parachromatin areas, and inconspicuous nucleoli. Histopathologically, atypical small lymphocytes infiltrated in the interstitium and alveolar sac. By the immunohistochemical study and molecular biologic study of gene rearrangement, the T cell clonality of atypical lymphoid cells was confirmed.

  • Background: The objective of this study was to investigate the MSCT characteristics of PTL in order to enhance the awareness of this uncommon entity among both clinicians and radiologists. Materials and Methods: The clinicopathological data and MSCT images of 27 patients with PTL were retrospectively reviewed. The MSCT appearances were classified into three types: type 1, solitary nodule surrounded by normal thyroid tissue; type 2, multiple nodules in the thyroid, and type 3, enlarged thyroid glands with a reduced attenuation with or without peripheral thin hyperattenuating thyroid tissue. Results: The patients were enrolled in the study with a mean age of 68 years (range, 51-86years) and compression symptoms or enlarged cervical lymph nodes at diagnosis. Hashimoto's thyroiditis was in 20 patients. All patients had non-Hodgkin lymphoma of B-cell in origin, including 22 cases of diffuse large B-cell lymphoma (DLBCL) and 5 of low-grade B-cell lymphoma of mucosa-associated lymphoid tissue (MALT). For MSCT appearance, type 1 pattern was observed in 2 patients, type 2 in 8, and seventeen type 3 in 17. The lesions occurred in more than one lobe with a mean maximal transverse diameter of 6.9 cm and an ill-defined margin. Most tumors showed a homogeneous attenuation equal to that of surrounding muscles before contrast and obvious enhancement after contrast. Cervical lymph node involvement and invasion of the trahea and (or) esophagus were mainly observed in patients with DLBCL. Conclusions: PTL should be clinically considered in elder patients presenting with a history of Hashimoto's thyroiditis and cervical lymphadenopathy. The MSCT characteristics of PTL includes a mass diffusely affecting more than one thyroid lobe, isointense to muscle and obvious enhancement before and after contrast. DLBCL, the most common histological subtype of PTL, is associated with a higher invasive tendency.

  • Helicobacter pylori infection is acquired mainly during childhood and causes various diseases such as gastritis, peptic ulcer disease, mucosa-associated lymphoid tissue (MALT) lymphoma, and iron deficiency anemia. Although H. pylori infection in children differs from adults in many ways, this is often overlooked in clinical practice. Unlike adults, nodular gastritis may be a pathognomonic endoscopic finding of childhood H. pylori infection. Histopathological findings of gastric tissues are also different in children due to predominance of lymphocytes and plasma cells and the formation of gastric MALT. Although endoscopy is recommended for the initial diagnosis of H. pylori infection, several non-invasive diagnostic tests such as the urea breath test (UBT) and the H. pylori stool antigen test (HpSA) are available and well validated even in children. According to recent data, both the $^{13}C$-UBT and HpSA using enzyme-linked immunosorbent assay are reliable non-invasive tests to determine H. pylori status after eradication therapy, although children younger than 6 years are known to have high false positives. When invasive or noninvasive tests are applied to children to detect H. pylori infection, it should be noted that there are differences between children and adults in diagnosing H. pylori infection.

  • 기관지 연관 림프조직 림프종은 비특이적인 호흡기 증상만을 나타내며, 전산화단층촬영에서 세기관지 폐포암, 림프구성 간질성 폐렴등과 뚜렷이 구분이 되지 않는 결절 외 림프종의 일종이다. 저자들은 비특이적인 호흡기 증상만을 나타내는 병변에 대해 침습적인 방법인 경피 미세흡입생검을 시행하여, 원발성 기관지 연관 림프조직 림프종으로 진단하였으며, 병리적 진단이 내려진 상태에서 치료를 목적으로 좌상엽 절제술을 시행하였다. 기관지 연관 림프조직 림프종은 서서히 진행되는 질환으로, 대부분 최종 진단이 늦어지는 경향을 보인다. 국소적 병변일 경우 외과적 수술로 완치가 가능한 질환이므로, 질환이 의심되는 경우 적극적 검사와 치료를 시도하는 것이 중요할 것으로 생각된다.

  • In case of neoplasm claims, it is important to make a decision of differentiating malignant and benign. In Korean insurance market, there are many insurance products that cover cancer. In the insurance claims adjustment, differentiation between malignant and benign is according to histologic findings. However there are many neoplasms of bad clinical course in spite of benign histopathologic classification. In this article; astrocytoma, thymoma, gastrointestinal stromal tumor, colonic intramucosal carcinoma, gastric high grade adenoma/dysplasia, carcinoid tumor, MALT lymphoma, revision of Korean Classification of Disease-6th edition, and bladder tumors are reviewed in terms of differentiation between malignant and benign in the insurance claims. It may be helpful for claims staff to review important neoplasms in terms of differentiation between malignant and benign.

  • Numerous persons complained dyspepsia even though no specific objective findings are revealed by imaging study, laboratory examinations and other clinical research. To find out of so many symptoms what they are, I would to approach by two ways. One way is oriental medical literatural study and the other is Helicobacter pylori infection that is accepted as one of most important causal factors of many gastric diseases. Background/Aims: Recently, the role of Helicobacter pylori as a causal factor in the etiology of gastric cancer, peptic ulcer, gastritis and low-grade gastric mucosa-associated lymphoid tissue(MALT) lymphoma is well known. Using endoscopy, biopsy urease testing and histology are recommanded as the tests of choice. Serological test is not recommanded at the moment because of its low sensitivity and espicially low specificity. The urea breath test is more sensitive and specific noninvasive test than serologic test, but it is not widely available yet. Methods/Results: We studied 90 cases by diagnostic endoscopy as a screening test for the persons complaining gastrointestinal symptoms. As a result eighteen persons are revealed to be Helicoacter pylori infected histologicaly. Conclusion: More specific literatural studies are requied.

  • 배경: 폐에 생기는 원발성 악성림프종은 매우 드문 종양이다. 비록 림프종의 예후는 좋으나 임상양상이나 예후요소, 치료에 대해서는 명확히 밝혀져 있지 않다. 대상 및 방법: 1994년부터 2006년 사이에 치료한 8명의 환자를 대상으로 하였다. 병리적 검사에서 폐에 악성 림프종으로 나타났으며 종격동림프선비대가 없으며 복부와 골반 단층촬영 및 골수검사에서 폐외 질병이 없으며 과거 림프종의 병력이 없는 경우로 하였다. 결과: 남자가 3명, 여자가 5명이었으며 평균나이는 53.9세였다. 3명은 무증상이었으며 5명은 폐 및 전신증상을 가지고 있었다. 진단은 3명이 흉부컴퓨터 단층촬영하 세침 생검, 1명이 기관지내시경하 생검을 하였으며 수술적으로 진행된 사람은 4명으로 폐쐐기 절제술 2명과 폐엽 절제술 2명을 시행하였다. 3명은 점막관련 림프종이었으며 2명은 큰 B세포 림프종, 2명은 소림프구 림프종이었고 한명은 여포성 림프종이었다. 8명의 환자들은 여러 다양한 치료를 받았는데 관찰, 수술, 항암화학요법 및 방사선치료나 복합치료를 받았다. 8명 모두 현재 생존해있으며 평균추적관찰기간은 38개월이다. 결론: 이 결과에서도 나타나듯 폐의 원발성악성림프종은 좋은 예후를 가지고 있으나 임상증상과 예후요소, 적절한 치료방식을 알아내기 위해서는 더 긴 기간의 추적관찰과 더 많은 임상경험이 필요하다.
