Background: This study aimed to characterize the histopathological pattern of lymph node pathology among Saudi patients and to highlight the age and gender variations of these lesions as base line data. Materials and Methods: We retrospectively analyzed the data from lymph node biopsy specimens received at the Department of Pathology, King Fahad Hospital, Madinah, Saudi Arabia from January 2006 to December 2013. Results: Of the 289 lymph node biopsy specimens received, 154 (53.3%) were from males and 135 (46.7%) from females giving a male: female ratio of 1.14:1. Age of the patients ranged from 2.5 to 96 years with a mean age 33.9 years. The commonest lymph node group affected was the cervical (30.4%) followed by axillary (9.7%) and inguinal (8.7%). Malignant lymphoma [71 Hodgkin's disease (HD), 57 non Hodgkin's lymphoma (NHL)] 128 (44.3%), reactive hyperplasia 68 (23.5%), and tuberculosis 41 (14.2%) were the common causes of lymph node enlargement. While HD, reactive hyperplasia and tuberculosis were commonest in young adult patients (10-29 years old) and rare above the age of 50 years; NHL was the predominant cause of lymph node enlargement above 50 years. Conclusions: Lymph node biopsy plays an important role in establishing the cause of lymphadenopathy. Among the biopsied nodes, lymphomas were the most common (44.3%) followed by non-specific reactive hyperplasia (23.5%) and tuberculous lymphadenitis (14.2%).

Tuberculosis is a chronic disease caused by Mycobacterium tuberculosis, which usually affects the lung but may cause lesions in any organ or tissue of the human body. Mediastinal lymph node involvement is common feature of intrathoracic tuberculosis in children. Sometimes the lymph node may be enlarged and it causes compressive symptoms. Recently we experienced two cases of tuberculous abscess at middle mediastinum. The abscess seemed to be originated from the mediastinal lymphadenitis, and caused the symptoms. Operation was performed by median sternotomy and by posterolateral thoracotomy incision respectively for the purpose of relieving symptoms and diagnosing the mediastinal mass. The symptoms were relieved completely and postoperative course was uneventful.

연구 배경 : 미세침 흡인 세포검사법은 말초 림프절 비대의 원인규명에 매우 우수한 선별검사로 알려져 있으나 각 원인질환이나 림프절의 이학적 소견에 따른 유용성이나 검사한계에 대한 연구는 아직 미진하다. 방 법 : 경부 림프절 비대를 주소로 내원한 16세 이상 성인환자들 중 진단을 위해 미세침 흡인 세포검사법을 시행 받고 외과적 조직 생검, 미생물 검사, 임상적추적관찰 등을 통해 최종 진단이 가능했던 342명을 대상으로 검사의 예민도와 유용성, 문제점이 각 원인 질환이나 림프절의 이학적 소견에 따라서 어떠한지를 후향적으로 알아보았다. 결 과 : 342명의 림프절 비대 환자 중 양성 병변은 176예인 51.5 %, 결핵성 림프절염은 88예로 25.7 %, 악성 종양의 전이는 66예로 19.3 %, 그리고 림프종은 12예로 3.5 %였다. 결핵성 림프절염, 악성 종양의 전이, 림프종 등으로 최종 진단된 환자군들은 양성 병변에 비해서 높은 연령을 보였고 남성이 많았으며 빗장위 림프절을 침범한 경우가 많았다. 림프절의 이학적 특징에서도 림프절의 평균 크기가 특이 질환이 있는 군에서 양성 병변인 군에 비해서 유의하게 컸으며 20 mm 이상의 크기를 가진 환자들의 수도 유의하게 많았다. 악성 종양의 전이인 경우에는 고정화됐거나 굳은 경도를 가진 경우가 유의하게 많았다. 미세침 흡인 세포검사법은 전체적으로 88 %의 진단 예민도를 보였으며 악성 종양의 전이인 경우가 90.1 % 로 가장 높았고 림프종인 경우에 58.3% 로 가장 낮았다 양성 병변인 경우는 88.6 %, 결핵성 림프절염인 경우는 77.3 %의 예민도를 보였다. 미세침 흡인 세포검사법의 진단 예민도는 질환의 종류나 비대 기간, 림프절의 크기 등과 관련이 없었고 다만 빗장위 림프절인 경우에는 80.0 % 로 다른경부 림프절의 91.3 % 에 비해서 유의하게 낮은 예 민도를 보였다.결 론 : 미세침 흡인 세포검사법은 림프절 비대의 원인 감별에 우수한 선별진단법으로 판단되나 림프종이 의심되거나 빗장위 림프절의 경우에는 낮은 진단율을 보이므로 주의해야 한다.

Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a standard procedure to evaluate suspicious lymph node involvement of lung cancer because computed tomography (CT) and $^{18}F$-fluorodeoxyglucose positron emission tomography-CT (PET-CT) have limitations in their sensitivity and specificity. There are a number of benign causes of false positive lymph node such as anthracosis or anthracofibrosis, pneumoconiosis, old or active tuberculosis, interstitial lung disease, and other infectious conditions including pneumonia. The purpose of this study was to evaluate possible causes of false positive lymph node detected in chest CT or PET-CT. Methods: Two hundred forty-seven patients who were initially diagnosed with lung cancer between May 2009 and December 2012, and underwent EBUS-TBNA to confirm suspicious lymph node involvement by chest CT or PET-CT were analyzed for the study. Results: Of 247 cases, EBUS-TBNA confirmed malignancy in at least one lymph node in 189. The remaining 58 patients whose EBUS-TBNA results were negative were analyzed. Age ${\geq}65$, squamous cell carcinoma as the histologic type, and pneumoconiosis were related with false-positive lymph node involvement on imaging studies such as chest CT and PET-CT. Conclusion: These findings suggest that lung cancer staging should be done more carefully when a patient has clinically benign lymph node characteristics including older age, squamous cell carcinoma, and benign lung conditions.

Metastatic squamous cell carcinoma from a cancer of unknown primary (CUP) affecting the intrathoracic lymph node is very rare. We reported a case of metastatic squamous cell carcinoma in the hilar and interlobar lymph node from a patient with CUP and reviewed the associated literature. Abnormal mass in the right hilar area was incidentally detected. A chest computed tomography scan showed a 2.5-cm diameter mass in the right hilum that had changed little in size for 3 years. The patient underwent a right pneumonectomy and mediastinal lymph node dissection. A metastatic squamous cell carcinoma in the hilar and interlobar lymph nodes without a primary lung or other lesion was diagnosed. The patient received adjuvant chemotherapy for a diagnosis of T0N1M0 lung cancer.

Accurate lymph node staging of lung cancer is crucial in determining optimal treatment plans and predicting patient outcome. Currently used lymph node maps have been reconciled to the internationally accepted International Association for the Study of Lung Cancer (IASLC) map published in the seventh edition of TNM classification system of malignant tumours. This article provides computed tomographic illustrations of the IASLC nodal map, to facilitate its application in day-to-day clinical practice in order to increase the appropriate classification in lung cancer staging.

The accuracy of fine needle aspiration cytology(FNAC) of the lymph node was investigated through a review of 176 FNAC cases and the corresponding biopsies. We chose 157 FNAC cases after the exclusion of 19 inadequate ones. Sensitivity of malignancy was 94.0%, specificity 100%, false negativity 6.0%, and false positivity 0.0%. The overall diagnostic accuracy was 96.8%. Sensitivity of metastatic carcinoma was 98.0% and that of malignant lymphoma was 87.9%. False negative cases included one metastatic carcinoma and four malignant lymphomas. The aspirates of metastatic carcinoma with false negativity exhibited a diffuse smear of keratin debris without viable cells, which led to the difficulty in differentiation from benign epithelial cyst. The cases of malignant lymphoma with false negative diagnosis were two Hodgkin diseases, one Lennert's lymphoma, and one peripheral T cell lymphoma in the histologic sections. On the analysis of 39 cases of tuberculosis, 17 cases(43.6%) were diagnosed as tuberculosis, 4(10.3%) as granulomatous lymphadenitis, 3(7.7%) as necrotizing lymphadenitis, and 15(38.5%) as reactive hyperplasia or pyogenic inflammation. Sensitivity of tuberculosis was 53.9%. In conclusion, lymph node FNAC is an excellent non-invasive diagnostic tool for the diagnosis of metastatic carcinoma. The diagnostic accuracy of malignant lymphoma could be improved with flow cytometry or polymerase chain reaction for antigen receptor genes. For the FNAC diagnosis of tuberculosis, AFB stain, culture, and PCR would be helpful as adjuvant techniques.

Neck dissection has become an integral part of the staging and management of head and neck tumors. This paper reports a series of head and neck patients who had pathological findings in their neck dissection specimens, which were unrelated to their primary tumors. In 7 cases, there was unexpected pathology in the cervical lymph nodes which was not related to the primary tumor. Four cases were squamous cell carcinomas and 3 were thyroid carcinomas. In 3 cases of squamous cell carcinomas, there were no evidence of metastatic squamous cell carcinoma in neck dissection specimen; however, the lymph nodes were found to be involved by metastatic papillary carcinoma in one larynx cancer, metastatic adenocarcinoma in the other larynx cancer, tuberculosis in one nasopharynx cancer. In three of neck dissection specimen of carcinoma(two thyroid carcinomas, one laryngeal carcinoma), dual nodal pathology was found: Each of these specimen contained carcinoma with tuberculosis of the lymph nodes in three cases. In one thyroid carcinoma, there was no evidence of metastasis; however, the lymph nodes were found to be involved by tuberculosis. Preoperative assessment did not reveal any findings to alert us to the possibility of a synchronous pathological process in the cervical nodes of this group of 7 patients. In particular, there was no evidence of active pulmonary tuberculosis in the 5 patients with active lymph node disease.

Cryptococcal pneumonia usually occurs in immunocompromised patients with malignancy, acquired immune deficiency syndrome, organ transplantations, immunosuppressive chemotherapies, catheter insertion, or dialysis. It can be diagnosed by gaining tissues in lung parenchyma or detecting antigen in blood or bronchoalveolar lavage fluid. Here we report an immunocompetent 32-year-old male patient with diabetes mellitus diagnosed with cryptococcal pneumonia after a ultrasound-guided percutaneous supraclavicular lymph node core needle biopsy. We treated him with fluconazole at 400 mg/day for 9 months according to the guideline. This is the first case that cryptococcal pneumonia was diagnosed from a percutaneous lymph node biopsy in South Korea.
