본 과에서는 우측 악하부의 부종 및 동통을 주소로 내원한 환자를 초기에 우측 악하부 및 협부 농양으로 진단하고 절개 및 배농술을 시행하였으나 증상의 호전이 없고 고열과 림프절 비대가 지속적으로 관찰되었다. 이에 저자 등은 비대된 임프절의 적출술과 다양한 검사를 통하여 괴사성 림프절염을 조직학적으로 확인하고 최종적으로 Kikuchi Fujimoto Disease로 확진하였다. Kikuchi-Fujimoto Disease는 임파선 비대와 고열이 동반되는 원인 불명의 괴사성 임파선염으로 특징지워지는 질환으로서, 적출생검을 통해 증상이 사라지는 경우가 많으므로 상기와 같은 증상이 동반된 환자의 경우 악성 림프종이나 전신성 홍반성 루푸스등의 여러 질환과의 감별진단을 통하여 정확한 치료를 시행하는 것이 추천된다.

PFAPA 증후군은 소아 시기의 주기성 발열의 원인의 하나로, 급작스럽게 시작되는 발열과 더불어 아프타 구강 궤양, 인두염과 경부 림프절염이 동반되는 것을 특징으로 하는 질환이다. PFAPA 증후군의 원인은 아직 알려져 있지 않으며, 가족력이 없이 산발적으로 발생한다. 또한 검사실 소견에서도 특징적인 소견은 없다. 진단은 임상적인 소견을 바탕으로 이루어지며, 장기적인 합병증을 남기지는 않는다. 현재까지 알려진 치료로는 경구프레드니솔론이 증상을 조절하는 데 효과적이라고 알려져 있다. 저자들은 2년간의 임상 증상의 반복을 경험하였던 6세 여아에서 다른 질환을 배제한 후 PFAPA 증후군의 진단 요건을 만족하여 경구 프레드니솔론을 사용한 후 증세의 호전을 보인 PFAPA 증후군의 한 예를 보고하고자 한다.

Infectious mononucleosis(IM) Is an acute self-limiting lymphoproliferative disorder associated with infection by the Epstein-Barr Virus(EBV), with the characteristic triad of fever, sore throat, and cervical or generalized lymphadenopathy. And also there are atypical lymphocytes in the peripheral blood. Cytological findings of IM lymphadenitis are characterized by a florid immunoblastic and atypical lymphoid cell proliferation. However, the small number of cases were studied by fineneedle aspiration cytology(FNAC) even though there was a complexity of lymph node pathology. It is important to recognize the reactive pattern of IM that would initiate EBV study and to avoid unnecessary biopsy We studied findings of lymph node FNAC from 4 patients with EBV infection confirmed by EBV-specific serologic studios. All of the cases were positive for viral capsid antigen(VCA) and one case was positive for anti-EBV nuclear antigen(EBNA). Cytologically, all of the cases exhibited high cellularity and atypia with great numbers of large immunoblastic lymphocytes.

Kimura's disease is a chronic Inflammatory disorder of unknown etiology, presenting usually as a painless subcutaneous swelling in the head and neck region or in the lymph nodes. We experienced a case of Kimura's lymphadenitis with characteristic Warthin-Finkeldey type polykaryocytes by fine needle aspiration cytology. The patient was a 10-year old male with two enlarged lymph nodes in the postauricular area. Fine needle aspiration cytology from the lymph nodes disclosed hypercellular smears with some scattered eosinophils and polykaryocytes in a polymorphous lymphoid background. There were also fragmented vessel wails and activated endothelial cell clusters in the slightly necrotic background. The Warthin-Finkeldey type polykaryocytes had three to thirty nuclei and prominent nucleoli with cytoplasmic borders. Their nuclei were arranged in grapevine or ring shaped clusters. As these polykaryocytes could also be found in lymph nodes and extranodal tissues of both reactive and neoplastic lymphoid disorders, polykaryocytes themselves are clinically nonspecific. However, the morphologic features of the Warthin-Finkeldey type giant cells are quite different from the foreign body type or Langhans' type giant cells. When the characteristic cytologic features of Kimura's disease such as significant number of eosinophils in a background of lymphoid cells asd proliferation of vessels and endothelial cells are also observed in the smear, it is possible to suggest this diagnosis in the appropriate clinical setting.

The efficacy of the fine needle aspiration biopsy and cytological examination(FNABC) under ultrasonographic(US) guides for the diagnosis of cervical tuberculous lymphadenitis was assessed. There were one hundred and one patients whose neck masses were proven to be tuberculous lymphadenites with cytologic and/or histologic diagnosis. The physical characteristics shown by US revealed that all the cases were multiple lesions. Multiregional lesions were found in 80 cases(79.1%) and 19 cases(18.8%) were the bilateral lesion. The region V was the most prevalent site(n=69, 68.3%). US findings revealed 92 cases(90.9%) showed hypoechoic lesions and 9(9.1%) showed mixed echo patterns. There was no hyperechoic lesion (p<0.05). The sensitivity of FNABC was 77.2% and specificity was 99.0%. Diagnostic accuracy was 85.0%. There was no complication during the procedures. FNABC for the diagnosis of cervical tuberculous lymphadenitis is a safe, convinient procedure and has a high specificity. The pitfall of FNABC the low sensitivity, seemed to be compensated by US evaluations.

Three cases of subacute necrotizing lymphadenitis diagnosed by fine needle aspiration (FNA) of enlarged lymph nodes are reported. The FNA smears contained randomly activated lymphoid cells, necrotic debris and histiocytes. The same patterns were found in subsequently examined excised lymph nodes from these cases. The differential diagnosis of this entity is discussed and the value of preparing FNA cell blocks and accompanying AFB stain with culture is emphasized. FNA may be able to provide a diagnosis in case of this benign disease, therefore avoiding a more traumatic excisional biopsy.

Thirty cases of Kikuchi's lymphadenitis, diagnosed by fine needle aspiration cytology, were reviewed to determine the main cytologic features helpful in reaching a diagnosis. The patients(mean age 26.6 years, male: female = 1:3.8) presented with lymphadenopathy (cervical 24, submandibular 3, and axillary 1) with or without fever and local tenderness. Excisional biopsy was done for confirmation in 5 cases and the remaining 25 cases showed the similar cytologic and clinical features. In the aspiration smears of all cases, there was a heterogenous celluar mixture including frequent extracellular karyorrhectic nuclear debris, phagocytic histiocytes, plasmacytoid monocytes, and a variable number of polymorphous lymphocytes such as immunoblasts, activated large lymphocytes, and small mature lymphocytes. The characteristic cytologic features of Kikuchi's lymphadenitis were the following: (1) frequent extracelluar karyorrhectic nuclear debris in the background : (2) phagocytic histiocytes with eccentrically placed crescentic nuclei and abundant pale cytoplasm containing phagocytized karyorrhectic debris : (3) plasmacytoid monocytes, which were medium-sized cells with eccentrically placed round nuclei and amphophilic cytoplasm : (4) no neutrophilic background.

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.

연구배경 : 최근에 ${\gamma}{\delta}$ T 램프구가 결핵균의 항원과 반응함이 알려져 ${\gamma}{\delta}$ T 림프구가 결핵균에 대한 방어기전에 관여할 가능성이 제시되고 있다. 본 교실의 연구와 다른 연구에 의하면 폐결핵 환자의 말초혈액에서 ${\gamma}{\delta}$ T 림프구의 숫적 증가나 기능의 활성화가 관찰되지 않아 폐결핵 환자에서 ${\gamma}{\delta}$ T 림프구는 전신적으로 활성화되지 않고 국소병변에서 방어기능을 나타내는 것으로 생각할 수 있다. 이에 저자들은 일차적으로 결핵의 국소병변으로 조직을 얻기가 쉬운 결핵성 림프절에서 ${\gamma}{\delta}$ T 림프구의 분포를 관찰하고자 본 연구를 시행하였다. 방법 : 조직검사상 결핵성 림프절염(n=5)과 반응성 과형성(reactive hyperplasia) (n=3)으로 진단된 환자의 림프절을 대상으로 CD4, ${\alpha}{\beta}$ TCR, ${\gamma}{\delta}$ TCR에 대한 단일 클론항체를 이용해 면역조직화학검사를 시행하였다. 결과 : 반응성 과형성 림프절에서는 총 T 림프구중 ${\gamma}{\delta}$ T 림프구의 비율이 $1.7{\pm}1.5%$였고 결핵성 림프절에서는 ${\gamma}{\delta}$ T 림프구가 전체 T 림프구의 $16.3{\pm}10.3%$를 차지하고 있어 결핵성 림프절에서 반응성 과형성 림프절에 비해 ${\gamma}{\delta}$ T 림프구의 침윤이 유의하게 증가되어 있었다(p<0.05). 결론 : ${\gamma}{\delta}$ T 림프구가 결핵균 감염 국소 병변부위에서 방어기전에 관여할 가능성이 있을 것으로 생각되고 향후 국소 결핵 병변에서의 ${\gamma}{\delta}$ T 림프구 기능에 관한 연구가 필요할 것으로 생각된다.

A 34-year-old man presented with a severe headache, fever, and cervical lymphadenopathy followed by generalized tonic-clonic seizure. Evaluations showed splenomegaly, elevated liver enzymes, and 380 white blood $cells/mm^3$ in the cerebrospinal fluid. Two weeks after admission, he developed sudden vertigo. Examination revealed spontaneous horizontal-torsional nystagmus to the right and bithermal caloric tests documented left canal paresis. A cervical lymph node biopsy disclosed subacute necrotizing lymphadenitis. We report a case of aseptic meningitis and unilateral vestibulopathy associated with histiocytic necrotizing lymphadenitis (Kikuchi's disease).
