RESUMEN
A 30-year-old man patient was admitted to our clinic with complaints including cough, dyspnea, and chest pain. He had been diagnosed with pulmonary Langerhans' cell histiocytosis (LCH) 9 years previously. HRCT of the thorax demonstrated the presence of diffuse emphysematous areas in both lungs with a honeycomb appearance, an increase in reticular density at the lower lobes, a mass lesion in the left hilus, and a mass lesion at the lower lobe of the left lung. Histological diagnosis of TBNA from the right lower paratracheal and subcarinal lymph nodes was adenocarcinoma. Chemotherapy was begun, but the patient died due to respiratory failure after two courses of chemotherapy. We present this case as an example of the rare development of bronchogenic carcinoma during the long-term course of LCH.

OBJECTIVE: To evaluate the diagnostic contribution and utility of bacteriologic surveys using bronchoscopic washing and gastric lavage in cases of radiologically suspected tuberculosis with no detectable acid-fast bacilli (AFB) in the sputum. MATERIAL AND METHODS: This prospective study performed bronchoscopic lavage following gastric washing in suspected pulmonary tuberculosis patients. The presence of AFB was determined via direct microscopy and materials were cultured in Löwenstein-Jensen medium. RESULTS: Thirty-eight consecutive patients were enrolled in the study (30 males and 8 females; mean age, 33.8 +/- 10.9 years). Three patients could not give sputum. In 23 of 35 cases (66%), sputum cultures (SC) were positive. In 17 cases (49%), gastric lavage cultures (GLC) were positive. Eighteen cases (55%) had positive bronchoscopic washing cultures (BWC). No statistically significant difference was observed when SC positivity was compared to GLC and BWC, and no difference was observed when the GLC results were compared with BWC. Tuberculosis was confirmed in 30 of 38 (79%) patients when SC and GLC were evaluated together, in 33 of 38 patients (87%) when SC and BWC were evaluated together, and in 36 of 38 (95%) when SC, GLC, and BWC were evaluated together (P = 0.016, P = 0.002, and P = 0.0001, respectively). The increase in positive cultures was statistically significant when gastric lavage was evaluated together with bronchoscopic washing (P = 0.004). CONCLUSION: Adding gastric lavage and bronchial washing to sputum culture could increase culture positivity for M tuberculosis bacilli in suspected pulmonary tuberculosis patients with AFB-negative sputum smears.

Primary tumors of the trachea are rare and can be missed because of the paucity of symptoms and findings and the difficulty in detecting them with chest radiographs. A 31-year-old male patient was admitted with complaints of shortness of breath, coughing, phlegm, and blood in the sputum. He stated that he was being treated for chronic obstructive pulmonary disease. Fiberoptic bronchoscopy revealed a vegetative mass with a wide base on the posterolateral wall of the distal one-third of the trachea. Postoperative histopathological examination revealed a typical carcinoid tumor. In patients with an unexplained cough, dyspnea, infrequent hemoptysis, and normal pulmonary imaging findings, tracheal carcinoma should be suspected. In such cases, early thoracic computed tomography and bronchoscopic examination can provide a rapid diagnosis and treatment options and prevent a false diagnosis.
