Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a technique developed to allow mediastinal staging of lung cancer and also to evaluate intrathoracic lymphadenopathy. In a tuberculosis-endemic area, tuberculosis should be considered as an etiology of mediastinal lymphadenopathy. The aim of this study was to investigate the utility of the routine culture for tuberculosis from specimens of EBUS-TBNA. Methods: We prospectively performed routine culture for tuberculosis from aspiration or core biopsy specimens got from 86 patients who had undergone EBUS-TBNA due to mediastinal lymphadenopathy between March 2010 and March 2011. Results: A total of 135 lymph node aspiration and 118 core biopsy specimens were included in this analysis. We confirmed the malignancy in 62 (72.9%), tuberculosis in 7 (8.1%), sarcoidosis in 7 (8.1%), asperogillosis in 2 (2.3%) and pneumoconiosis in 2 (2.3%) patients. One lung cancer patient had pulmonary tuberculosis coincidentally and 5 patients had unknown lymphadenopathy. The number of positive culture for Mycobacterium tuberculsosis by EBUS-TBNA is 2 (1.5%) from 135 lymph node aspiration specimens and 2 (1.7%) from 118 core biopsy specimens. Out of eight patients confirmed with tuberculosis, only one patient had positive mycobacterial culture of aspiration specimen from EBUS-TBNA without histopathologic diagnosis. Conclusion: These results propose that routine culture for tuberculosis from EBUS-TBNA may not provide additional information for the diagnosis of coincident tuberculous lymphadenitis. However, if there is any possibility of tuberculous lymphadenopathy or pulmonary tuberculosis, it should be considered to perform EBUS-TBNA in patients who have negative sputum AFB smears or no sputum production.

단순 흉부 X-선에서 양측성 폐문 림프절 비후를 보이는 대표적인 질환으로 유육종증, 림프종, 결핵, 폐암, 아밀로이드증, 브루셀라증, 콕시디오이데스진균증(Coccidioidomycosis) 등이 있다. LIP의 방사선학적 소견은 보통 비특징적이고, 초기 병변에서 양측 폐하에 망상, 망상결절성 침윤을 보이며 병이 진행됨에 따라 낭성 변화를 동반하고, 봉소상을 보이는 경우가 있으나, 본 증례의 환자와 같이 종격동과 양측 폐문에 림프절 종대를 동반하는 경우에 대한 보고는 흔치 않다. 저자들은 흉부 X-선 및 CT상 종격동과 양측 폐문부의 림프절 종대를 동반한 간질성 결절성 폐침윤 소견을 나타낸 환자에서 흉강경하 폐 생검을 통해 진단된 LIP를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Langerhans' cell histiocytosis is a relatively rare disorder of children, characterized by abnormal proliferation of Langerhans' cells. It usually presents as multiple osteolytic lesion with lymphadenopathy or cutaneous manifestations. We experienced a case of Langerhans' cell histiocytosis involving bone and lymph node, diagnosed by fine needle aspiration cytology of the lymph node. The patient was a 10-year old girl with left inguinal lymphadenopathy. Fine needle aspiration cytology from the lymph node disclosed very cellular smear consisted of Langerhans' cells, eosinophils and lymphocytes. The Langerhans' cells had eccentric oval to reniform shape nuclei with grooving and abundant pale cytoplasm. The diagnosis was confirmed later by histologic study of bone lesion.

A case of Burkitt lymphoma diagnosed through fine needle aspiration cytology is described, A 66-year-old man presented with lymphadenopathy on the right cervical neck and axillary area. An ultrasonogram and CT scan for the cervical neck showed a multiple variable sized lymphadenopathy with pericapsular invasion and necrotic foci, Fine needle aspiration cytology (FNAC) of the cervical lymph nodes revealed very cellular and necrotic smears consisting of diffusely scattered intermediate monotonous round cells, tingible body macrophages and many mitotic figures. Histological features of the excised lymph nodes showed the classic morphological features of Burkitt lymphoma. Recognition of the characteristic cytological features can suggest the possibility of Burkitt lymphoma.

A 12-year-old dog was referred due to multiple superficial lymphadenopathy. On cytology, each lymph node showed different cell populations where some of them consisted of intermediate to large lymphocytes with frequent Mott cells. Presence of Mott cells along with immature lymphocytes made the cytological diagnosis challenging, and therefore, supplementary diagnostic tests including PCR for Antigen Receptor Rearrangement (PARR) assay and flow cytometry were performed. This case report illustrates the value of flow cytometry in the diagnosis of lymphadenopathy with ambiguous cytologic findings.

A dog was presented with a cough, dyspnea, nasal discharge, gagging, and exercise intolerance. The dog showed leukocytosis, peripheral eosinophilia, and an increase C-reactive protein. The radiographic findings noted bronchointerstitial infiltration, intrathoracic lymphadenopathy, and soft tissue opacity mass. Computed tomography findings showed thickening of the bronchus and bronchiole. Also, peri-bronchial consolidation and generalized intrathoracic lymphadenopathy was present. On blind bronchoalveolar lavage and pulmonary cytology, there were significantly increased eosinophils. Canine pulmonary respiratory pathogens from a real-time polymerase chain reaction analysis was negative. Consequently, the dog was diagnosed with eosinophilic bronchopneumopathy. Clinical signs improved significantly within a few days after treatment with an oral corticosteroid.

Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is highly accurate in diagnosing mediastinal lymphadenopathies of lung cancer and benign disorders. However, the utility of EBUS-TBNA in the diagnosis of mediastinal lymphomas is unclear. The aim of this study was to determine the diagnostic value of EBUS-TBNA in patients with suspected lymphoma. Materials and Methods: Sixty-eight patients with isolated mediastinal lymphadenopathy and suspected of lymphoma were included in the study. EBUS-TBNA was performed on outpatients under moderate sedation. The sensitivity, specificity, negative predictive value and diagnostic accuracy of EBUS-TBNA were calculated. Results: Sixty-four patients were diagnosed by EBUS-TBNA, but four patients with non-diagnostic EBUS-TBNA required surgical procedures. Thirty-five (51.5%) patients had sarcoidosis, six (8.8%) had reactive lymphadenopathy, nine (13.3%) had tuberculosis, one (1.5%) had squamous cell carcinoma, two (2.9%) had sarcoma and fifteen (22%) had lymphoma (follicular center cell, large B-cell primary, and Hodgkin lymphomas in three, two, and ten, respectively). Of the 15 lymphoma patients, thirteen were diagnosed by EBUS and two by thoracotomy and mediastinoscopy. The sensitivity, specificity, negative predictive value, and diagnostic accuracy of EBUS-TBNA for the diagnosis of lymphoma were calculated as 86.7%, 100%, 96.4%, and 97%, respectively. Conclusions: EBUS-TBNA can be employed in the diagnosis of mediastinal lymphoma, instead of more invasive surgical procedures.
