Histiocytic necrotizing lymphadenitis (Kikuchi-Fujimoto disease, KFD) is a benign self-limiting lesion that can self-heal when no severe symptoms are present. KFD resembles tuberculous lymphadenitis and malignant lymphoma. Thus, early differential diagnosis will minimize unnecessary evaluation and treatment. Histological examination of a lymph node biopsy or fine needle aspiration could be a reliable method for KFD diagnosis. This study reports a case of histiocytic necrotizing lymphadenitis of the right cervical lymph node in a 52-year-old female patient. According to the fine needle aspiration biopsy result, the patient was diagnosed with Kikuchi-Fujimoto disease and treated with prednisolone (15 mg/day). After treatment, there was no recurrence or adverse event.

Cervical neck dissection is a frequent technique during treatment for oral squamous cell carcinoma (SCC). Occasionally, specimens harvested as cervical lymph nodes reveal thyroid tissue and need differentiation with metastatic thyroid cancer and ectopic thyroid tissue. Here, we report a case of an ectopic thyroid tissue with lymphocytic thyroiditis mimicking thyroid cancer metastasis at the cervical lymph node.

경화성 장간막염은 장간막에 만성 염증과 섬유화를 보이는 드문 질환으로 비교적 양호한 경과를 가지는 질환이다. 복부 컴퓨터단층촬영을 포함한 특징적 영상소견이 진단에 도움이 된다. 그러나 경화성 장간막염은 몇몇 악성 질환들과 유사한 형태를 보일 수 있으며, 이들은 치료방법 및 경과 자체가 완전히 다르기 때문에 악성 질환에 대한 적극적 배제가 중요하다. 저자들은 체중 감소 및 지속되는 설사 증상으로 내원한 75세 남성 환자가 복부 컴퓨터단층촬영상 장간막 혈 관 주변 연무양 감쇄의 특징적 소견을 보여 경화성 장간막염 으로 오인하였으나, 추적관찰 및 추가적으로 시행한 조직검 사와 양성자방출 컴퓨터단층촬영술을 통하여 최종적으로 총담관암과 그에 동반된 림프절전이로 진단하였던 드문 증 례를 경험하여 이를 보고하고자 한다.

This study was performed to investigate the correlation between the primary squamous cell carcinoma in oral cavity (POSCC) and paired metastatic oral squamous cell carcinoma in cervical lymph node (MOSCC) via immunohistochemical staining with Ki-67 and p53. The subjects included ten patients (20 specimens) who were diagnosed with OSCC with metastatic lymph nodes from 2010 to 2015 and surgically treated involving neck dissection in Kyungpook National University Hospital. Twenty specimens were stained immunohistochemically with Ki-67 and p53. The degrees of immunostaining by Ki-67 and p53 was evaluated as 0 (no positive cells), weak (1~25% positive cells), moderate (26-50% positive cells) and strong (>50% positive cells). Despite the strong tendency, there was no statistically significant result between expressions of Ki-67 and p53 in POSCC or MOSCC. We found that high expression of Ki-67 was significantly correlated with poor degree of differentiation. Our results suggest that expression of Ki-67 may be a predictable factor for degree of differentiation of POSCC and MOSCC.

Metastatic spread to cervical lymph nodes(LNs) is a major determinant of outcome in oral squamous cell carcinoma (SCC). To provide an useful method for the detection of lymph node micrometastases, we fulfilled the histopathological examination and reverse transcriptase polymerase chain reaction(RT-PCR) using the paraffin-embedded LNs of oral SCC patients. In this study, 78 LNs from 12 patients with primary oral SCC were analyzed. Metastases in the regional LNs were evaluated by RT-PCR for squamous cell carcinoma antigen(SCCA) and cytokeratin 5(CK5). Detectability of metastatic LNs by RT-PCR was compared with histopathological examination. Of 78 LNs, CK5 and SCCA mRNA were detected in 32(41.0%) and 8(10.3%), respectively. Histopathologically, 10(12.8%) of 78 LNs were positive. CK5 mRNA was detected in all 10 histopathologically positive LNs. In contrast, SCCA mRNA was detected in 5 of 10 histopathologically positive LNs. These findings suggest that genetic diagnosis by RT-PCR based on CK5 mRNA expression may be sensitive and clinically useful technique to detect the presence of metastatic carcinoma cells in regional lymph nodes of oral SCC.

마사지 치료는 한국에서 가장 일반적인 치료 도구의 하나로써 물리치료에서 적용되고 있으며 방법도 빠르게 변하고 있다. 지금까지 여러 형태의 마사지 방법들이 국내 물리치료사에게 소개 되어왔지만 림프흡수 마사지는 임상결과가 이전의 연구에서 제시되어 왔음에도 제대로 소개되지 않아서 일반적인 치료적 마사지 방법의 하나로 사용되고 있지는 않았다. 이에 본 연구자들은 현재 국제 림프학회에서 공인된 보더 스쿨의 엠엘디 코스를 임상 물리치료사들에게 소개함으로 해서, 국

The purpose of this study is to evaluate which clinicopathologic factors are associated with central lymph node metastasis (CLNM) in papillary thyroid carcinoma (PTC). A total of 402 cases of PTC were divided into two groups: CNLM (+) and CLNM (-). In univariate analysis, CLNM showed correlation with sex, tumor size, multifocality, bilaterality, extrathyroid extension, and distance from the capsule. In multivariate analysis, male gender, >1 cm of tumor size, multifocallity and extrathyroid extension were significant risk factors for CLNM. Findings of this study suggest that clinicians should pay attention to the above mentioned significant risk factors when examining lymph node (LN) for deciding LN dissection.

We previously examined extracts, isolated from Scutellaria baicalensis (SB), chemical mediators, and IgE by mesenteric lymph node (MLN) lymphocytes in rats. The present study was to evaluate the effects of extracts of SB on the MLN lymphocytes function of mice given orally by 20 mg/kg for 2 weeks with dextran sulfate sodium (DS)-induced colitis. Results show that IgE levels in MLN lymphocytes was low, while IgA was high, in mice given SB compared to that fed water. Concentrations of Inteferon-γ and interleukin (IL)-2 of T cells by concanavalin A treatment was significantly higher in the SB fed group than the normal group. Activation-induced IL-4 and IL-10 secretion was lower in SB fed mice compared control mice after DS-induced colitis. These results suggested that SB suppresses the inflammation in DS-induced colitis through the modulation of Th1/Th2 balance to down-regulate TH2 response in MLN lymphocytes.

Phellinus linteus (PL), one of the immune-regulatory substances, is recognized to play the role in the metabolic process on inflammation and immunity. It has been traditionally used in the oriental medicine to treat inflammatory related disease. The purpose of this study was to evaluate the effects of water extracts of PL on the mesenteric lymph node lymphocytes immune function in the ICR male mice. Control mice received vehicle only. The PL treated mice were administered the respective extract by oral gavages for 4 weeks. IgE concentrations in serum and MLN lymphocytes were significantly lower in PL treated mice than in control mice. PL increased the proportion of CD4+ and CD8+ T cells in MLN lymphocytes. PL significantly decreased Th2 cytokine concentrations and mRNA expression levels in cytokine secretions. Therefore, water extracts of PL modulate inflammatory parameters through regulation of immunoglobulin production resulting from decreased Th2 cytokine secretion and mRNA expression levels and reduce pro-inflammatory cytokine secretion and mRNA expression in MLN lymphocytes.
