  • Background:Subacute necrotizing lymphadenitis or Kikuchi's disease is unknown ethiology and self-limiting process. This disease predominantly affects young women age but rarely affects pediatrics, and usually manifests as lymphadenopathy and fever. Even though this disease is self-limited, benign process, many cases are misidentified as malignant lymphoma. The purpose of this study is to report the clinicopathologic finding, radiological finding and many labolatory test and to compare with characteristics of adult patients in this disease. Meterial and Methods:We reviewed 27 pediarics patients with subacute necrotizing lymphadenitis by excision biopsy or fineneedle aspiration cytology.Result:The most common symptomes were palpation of cervical lymh node(88.9%) and fever(66.7%). The common site of the involvement was cervical lymph node. The multiple involvement was 93% and bilateral involvement was 59%. Leukopenia(52%) and elevated erythrocyte sedimentation rates(93%) appeared in abnormal laboratory data. Microscopically, the characteristic finding was the wide area of florid nuclear dusts engulfed by histiocytes and well-circumscrbed area with eosinophilic fibrinoid material. There was a striking degree ofkaryorrhexis and an absence of granulocyte with paucity of plasma cell. All patients recovered with the conservative treatment and there was no specific complication and recurrence. Conclusion : We reviewed pediatric patients with this disease. Characteristics of this disease inpediatric patients were similar to adult patients.

  • Background and Objectives: Subacute necrotizing lymphadenitis or Kikuchi's disease has now become recognized in many parts of the world as a well-defined clinicopathologic entity. It typically affects cervical lymph nodes of young women, and subsides spontaneously within a few months without recurrences. The purpose of this study is to report the clinicopathologic finding, radiologic finding and many laboratory tests to elaborate the criteria that are useful in distinguishing this entity from inflammatory disease, granulomatous disease, lymphoma, malignant disease. Material and Methods: Authors evaluated 22 patients, who were diagnosed as subacute necrotizing lymphadenitis on excisional biopsy or fine needle aspiration cytology with retrospective chart review. Results: The patient population consisted of 21 women and 1 men. The mean age was 25 years old(range 17 to 42 years). All patient had palpable neck mass and associated fever, headache, weight loss, otalgia, diarrhea, night sweating. and associated disorder is dermatitis, hepatitis B, SLE, Hashimoto's thyroiditis, albinism et al. The multiple bilateral involvement of cervical lymph node was 20 cases(91%) and multiple unilateral 18 cases(82%), multiple bilateral 2 cases(9%). Solitary involvement was 2 cases(9%), mean size of involved lymph node was 2.0cm. In laboratory tests, leukopenia 17 cases(72%), elevated ESR 12 cases(54%), elevated GOT, GPT 3 cases(13%). In CT finding, lymph nodes enhanced in homogeneous fashion, and there was no evidence of central necrosis. Conclusion: Subacute necrotizing lymphadenitis, Kikuchi's disease may be easily confused clinically, pathologically, radiologically with malignant lymphoma, inflammatory disease, granulomatous disease. We should consider open biopsy of lymph node in the patient which had unilateral multiple cervical lymph node and in laboratory tests, were leukopenia, elevated ESR, especially in young women. otherwise, result of fine needle aspiration biopsy is nonspecific, excisional biopsy is recommended in order to differentiate other disease.

  • Purpose: This study was done to determine the usefulness of serum pepsinogen (PG) levels as a screening method for gastric cancer, and to assess the relationships between serum PG and clinicopathologic factors of gastric adenocarcinoma. Materials and Methods: Serum PG concentrations were measured in 94 subjects who were classified into (a) a control group (50 subjects) without abnormal endoscopic finding on a health checkup, or (b) a gastric cancer group (44 subjects) who had surgery at Daegu Catholic University Hospital between Nov. 2008 and May 2009. Receiver operator characteristic curves were utilized to select the most suitable test. Using different cutoff points, sensitivity and specificity were calculated. We compared preoperative serum PG levels with several clinicopathologic findings for patients with gastric adenocarcinoma. Results: The Serum PG I:II ratio was the most useful as a screening test. The sensitivity and specificity of PG screening for gastric cancer were, respectively, 81.8% and 82%. The cut off point correlated with the type of intestinal cancer (Lauren classification; P=0.003), tumor stage (P=0.001), and gastric adenocarcinoma with peritumoral chronic atrophic gastritis (P=0.036). Conclusion: Serum PG levels were found to be a potentially useful screening test and to correlate with clinicopathologic factors in gastric cancer patients. But, in order to use serum PG found in a health checkup for gastric cancer as a clinical application a large scale study is recommended.

  • Background: The basal cell carcinoma (BCC) is the most common non-melanoma skin cancer (NMSK). BCC might develop because of the faulty cell cycle arrest. $p15^{INK4b}$ is a tumor suppressor gene, involved in cell cycle arrest and inactivated in most human cancers. The role of $p15^{INK4b}$ protein expression in the genesis of BCC is as yet unknown. In a previous study we showed the absence of $p15^{INK4b}$ expression in the majority of tissue microarray cores of cutaneous squamous cell carcinoma (SCCs), another type of non-melanoma skin cancer, indicating that $p15^{INK4b}$ could possibly be involved in the pathogenesis of cutaneous SCC. The aim of this study was to investigate $p15^{INK4b}$ protein expression in BCCs. Materials and Method: Protein expression of $p15^{INK4b}$ in 35 cases of BCC tissue arrays and 19 cases of normal human skin tissue was studied using an immunohistochemical approach. Results: The expression of $p15^{INK4b}$ was not significantly different in the BCC cases as compared with normal human skin (p=0.356; p>0.05). In addition, there were no significant relationship between clinicopathologic variables of patients (age and sex) and $p15^{INK4b}$ protein expression. Conclusions: Our finding may indicate that $p15^{INK4b}$ protein expression does not play a role in the genesis of BCC.

  • Background & Method : Bronchiolitis obliterans organizing pneumonia(BOOP) is a specific clinicopathologic condition characterized by chronic inflammatory interstitial infiltrates. Cryptogenic form of BOOP presents subacute clinical course of flu-like illness, such as cough, fever, dyspnea with exertion and other constitutional symptoms. Pathologically it shows the presence of granulation tissue filling the lumen of terminal and respiratory bronchioles, extending into distal airspaces. Recently, we reviewed 24 cases of idiopathic type of BOOP, 5 cases of our hospital and another 19 cases on Korean literatures, and compared with reviewed data from foreign literatures. Results : Mean age was 54 years old and there was female preponderance in domestic reports. Their common presenting symptoms were dyspnea and cough, and mean duration of illness was 41 days. On chest examination, inspiratory crackle was a common finding. The laboratory findings were nonspecific except hypoxemia. Lung function studies revealed restrictive defect or combined obstructive and restrictive pattern in most patients. Bilateral patchy and nonsegmental alveolar opacities constituted characterized radiographic finding, highlighted on high resolution computed tomogram. It showed a favorable prognosis with an excellent responsiveness to corticosteroid therapy. The clinical features and laboratory findings were similar between domestic and foreign cases except female preponderance in Korean cases. Conclusion : If the clinical course is atypical or pregressive under proper treatment, clinicians should reevaluate clinical features and radiographic findings under the consideration of BOOP. Tissue confirmation would be recommended for the definitive diagnosis of BOOP.

  • Purpose: Submucosal gastric carcinomas metastasize to lymph nodes more often than the intramucosal gastric carcinomas. The objectives of this study are to clarify the characteristics of submucosal gastric carcinomas, especially in reference to the status of lymph node metastasis, and to explore the possibility of a minimally invasive operation. Materials and Methods: The clinicopathologic features of 88 patients with submucosal gastric carcinoma, all of whom were treated with a $D_{2}+\alpha$ gastrectomy between January 1994 and December 1999, were examined retrospectively with respect to the status of lymph nodes. The size, depth of submucosal invasion, histologic differentiation, location,and macroscopic finding of the tumor were investigated in association with the presence or the absence of lymph node metastasis. Results: Among the 88 patients, 15 ($17.05\%$) had lymph node metastasis, and the status of metastasis was significantly correlated with tumor size and depth of submucosal invasion. The frequency of metastasis was $0\%$ (0/7) of up to 1.0 cm and $18.5\%$ (15/81) over 1.0 cm in size (p=0.034) and $6.1\%$ (2/33) of up to 1.0mm and $23.6\%$ (13/55) over 1.0 mm in depth of submucosal invasion (p=0.042). Conclusion: The tumor size and depth of submucosal invasion are useful indicators of lymph node metastasis in submucosal gastric carcinoma. A minimally invasive operation can be applied for submucosal gastric carcinoma up to 1.0 cm in size Further studies are needed to limited surgery for depth of submucosal invasion.

  • Ameloblastoma, a benign tumor of odontogenic type, represents 10% of all tumors of the jaw. It is localized in the mandible(80%) and in the maxilla(20%). In every case, the selection of the surgical treatment must consider some fundamental elements, including the age and general state of health the clinicopathological variant, and the localization and extent of the tumor. This study was invested the clinicopathological findings of 23 patients with ameloblastoma which had been diagnosed by biopsy during the period of 1987 to 2005 at Chonnam National University Hospital. And it contained the statistical analysis according to the treatment methods and the clinicopathological findings such as sex, age, location, chief complaints, duration, radiographic findings, histologic findings, treatment methods. The results obtained are were follows. The age of patient ranged from 10 to 91 years(means, 35.9 years) at biopsy. Thirteen(57%) of the 23 subjects were males, and 10(43%) were females. Twenty(87%) of the 23 ameloblastomas were located in the mandible. Swelling was the most common symptom and was experienced by 20(87%) patients. Radiographically, 11(48%) of the 23 tumors were unilocular with a well-demarcated border and 12(52%) were multilocular. The most common histologic pattern was plexiform and acanthomatous rather then follicular. Conservative treatment was performed 7 cases(30%), radical treatment 11 cases(48%), and combined treatment 5 cases(22%). Follow-up period ranged from 2.1 years to 22 years(mean 5.1 years). Based on the above results, surgical excision after marsupialization was found to be useful as a preliminary treatment of the large cystic ameloblastoma in children and adolescents. On the contrary, the lesion with a soap bubble appearance, the one with ineffective marsupialization was subjected to extensive excision of the tumor with a wide margin of normal bone.

  • Idiopathic bronchiolitis obliterans with organizing pneumonia(BOOP) is a specific clinicopathologic syndrome characterized by a pneumonia-like illness, with excessive proliferation of granulation tissue within bronchioles, alveolar ducts and alveoli. The changes are most numerous in alveolar ducts. The presence of intraluminal tufts of organizing connective tissue in alveolar ducts and more distal airspaces has been termed organizing pneumonia. The radiologic manifestations are distinctive with bilateral, diffuse alveolar opacities predominantly in the subpleural and lower lung zone. Patchy migratory pneumonic foci or solely nodular infiltrates are rarely present in BOOP. BOOP is a diagnosis of importance because of its dramatic response to steroids.

  • Discogenic pain which develops during the degenerative process of intervertebral disc is an intractable disease of musculoskeletal system. Unlike other diseases in modern medical science, it is not clinically confirmed through objective imaging and clinicopathologic index. Moreover, current technology has been facing difficulties finding fundamental treatment. This study examined through reviewing literature whether the therapeutic rationales of interventional procedures for the discogenic pain, such as nerve block, intradiscal electrothermal therapy and nucleoplasty, are valid and whether safety reviews such as preclinical tests are carried out faithfully during the technology development process. As a result, it is presumed that there is not yet an interventional treatment for discogenic pain, whose therapeutic rationale has been objectively verified. And there are some cases of interventional treatment that have not been adequately equipped with the preclinical test steps necessary to review the safety of the procedure during the technology development process. In conclusion, since there is still no interventional treatment for discogenic pain which has clear therapeutic rationale, it is necessary to recognize that a more careful approach is needed to judge whether the procedure is performed in clinical settings. And medical ethical issues may arise for some interventional treatment that are deemed to have been carried out without a thorough review of safety.
