Lymphomatoid granulomatosis (LYG) is an angiocentric and angiodestructive neoplastic proliferation of B and T lymphocytes commonly involving the lungs. Epstein-Barr virus is commonly detected in lesional cells. We report a case of a 54-year-old female with underlying monoclonal gammopathy of unknown significance who presented with a 4 week history of dyspnea and cough. Computed tomography scan of the chest showed multiple lung nodules as well as endobronchial narrowing causing atelectasis at the left upper lobe. Bronchoscopic findings revealed obstruction at the lingula segment due to endobronchial mass as a rare presentation. Bronchoscopic biopsy was diagnosed with LYG grade 1. After treatment, the endobronchial mass and lung lesions were completely resolved. However, the patient eventually evolved to malignant lymphoma after 1 year.

Background : Endobronchial tuberculosis is definded as tuberculous infection of the tracheobronchial tree with microbiological and histopathological evidence. Endobronchial tuberculosis has clinical significance due to its sequela of cicatrical stenosis which causes atelectasis, dyspnea and secondary pneumonia and may mimic bronchial asthma and pulmanary malignancy. Method : The authors carried out, retrospectively, a clinical study on 201 patients confirmed with endobronchial tuberculosis who visited the Department of Pulmonary Medicine at Hangyang University Hospital from January 1990 10 April 1996. The following results were obtained. Results: 1) Total 201 parients(l9.5%) were confirmed as endobronchial tuberculosis among 1031 patients who had been undergone flexible bronchofiberscopic examination. The number of male patients were 55 and that of female patients were 146. and the male to female ratio was 1 : 2.7. 2) The age distribution were as follows: there were 61(30.3%) cases in the third decade, 40 cases(19.9%) in the fourth decade, 27 cases(13.4%) in the sixth decade, 21 cases(10.4%) in the fifth decade, 19 cases(9.5%) in the age group between 15 and 19 years, 19 cases(9.5%) in the seventh decade, and 14 cases(7.0%) over 70 years, in decreasing order. 3) The most common symptom, in 192 cases, was cough 74.5%, followed by sputum 55.2%, dyspnea 28.6%, chest discomfort 19.8%, fever 17.2%, hemoptysis 11.5%, in decreasing order, and localized wheezing was heard in 15.6%. 4) In chest X-ray of 189 cases, consolidation was the most frequent finding in 67.7%, followed by collapse 43.9%. cavitary lesion 11.6%, pleural effusion 7.4%, in decreasing order, and there was no abnormal findings in 3.2%. 5) In the 76 pulmanary function tests, a normal pattern was found in 44.7%, restrictive pattern in 39.5 %, obstructive pattern in 11.8%, and combined pattern in 3.9%. 6) Among total 201 patients, bronchoscopy showed caseous pseudomembrane in 70 cases(34.8%), mucosal erythema and edema in 54 cases(26.9%), hyperplastic lesion in 52 cases(25.9%), fibrous s.enosis in 22 cases(10.9%), and erosion or ulcer in 3 cases(1.5%). 7) In total 201 cases, bronchial washing AFB stain was positive in 103 cases(51.2%), bronchial washing culture for tuberculous bacilli in 55 cases(27.4%). In the 99 bronchoscopic biopsies, AFB slain positive in 36.4%. granuloma without AFB stain positive in 13.1%, chronic inflammation only in 36.4%. and non diagnostic biopsy finding in 14.1%. Conclusions : Young female patients, whose cough resistant to genenal antitussive agents, should be evaluated for endobronchial tuberculosis, even with clear chest roentgenogram and negative sputum AFB stain. Furthermore, we would like to emphasize that the bronchoscopic approach is a substantially useful means of making a differential diagnosis of atelectasis in older patients of cancer age. At this time we have to make a standard endoscopic classification of endobronchial tuberculosis, and well designed prospective studies are required to elucidate the effect of combination therapy using antituberculous chemotherapy with steroids on bronchial stenosis in patients with endobronchial tuberculosis.

Endobronchial actinomycosis is a rare chronic suppurative granulomatous infection of the bronchus, and this is sometimes related with a foreign body or a broncholith. The traditional treatment of endobroncial actinomycosis is intravenous antibiotics for 2 to 6 weeks and then oral antibiotics therapy for 6 to 12 months. We report here on 2 cases of endobronchial actinomycosis that were associated with a broncholith and a foreign body, respectively. Surgery followed by short term antibiotics therapy for only 20 days and 34 days, respectively, was effective as treatment for the endobronchial actinomycosis in our cases. After treatment, there were no complications or recurrence during the following period. We suggest that short term antibiotics therapy combined with a surgical operation might be effective as treatment for primary endobronchial actinomycosis, and especially when this illness is combined with a foreign body or a broncholith, as compared with traditional long term antibiotic therapy.

Tuberculosis remains as a major public health problem worldwide. In addition to classic pulmonary tuberculosis, tuberculosis may sometimes present atypically. In the case of atypical tuberculosis, the unusual sites and properties that mimic other diseases can lead to a misdiagnosis and therapeutic delay. Abdominal and pharyngeal tuberculosis are uncommon extrapulmonary manifestations of tuberculosis. To the best of our knowledge, a combination of abdominal and pharyngeal tuberculosis with endobronchial tuberculosis has not been reported. We report a case of concurrent abdominal and pharyngeal tuberculosis in a patient with chronic endobronchial tuberculosis mimicking a metastatic malignancy on computed tomography and FDG-PET.

Mycobacterium avium has been traditionally described as an opportunistic organism that causes disseminated disease in human immunodeficiency virus-positive patients and acts as a pulmonary pathogen in patients with underlying lung diseases such as chronic obstructive pulmonary disease or previously treated tuberculosis. Infections caused by M. avium in immunocompetent hosts usually manifest as 2 distinct subtypes, the upper lobe cavitary form and the nodular bronchiectatic form. However endobronchial lesions due to M. avium infections in immunocompetent host are reasonably rare, and there are no reports of this condition in Korea. We report here a case of endobronchial lesions involved in an M. avium infection in an immunocompetent 21 year-old female patient with no preexisting lung disease.

Aspergillus fumigatus causes a variety clinical syndrome in lung including aspergilloma, chronic necrotizing aspergillosis, invasive pulmonary aspergillosis, and allergic bronchopulmonary aspergillosis. Aspergilloma develops by a colonization and growing of Aspergillus inside lung cavities with underlying lung disease. There is a few report of endobronchial aspergilloma without lung parenchymal lesion. We experienced a case of endobronchial aspergilloma did not fit any category of Aspergillus-induced lesion, who show minimal fibrostreaky denstities on chest PA and chest CT. Massive hemoptysis was improved by a removal of the aspergilloma in this patient. Here, we report a rare case of endobronchial aspergilloma showing massive hemoptysis with review of literatures.

We presented a case of unusual endobronchial inflammatory polyps as a complication following endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in a patient with tuberculous lymphadenitis. EBUSTBNA of the right hilar lymph node was performed in a 29-year-old, previously healthy man. The patient was confirmed with tuberculous lymphadenitis and received antituberculosis medication over the course of 6 months. Chest computed tomography, after 6 months of antituberculosis therapy following the EBUS-TBNA showed nodular bronchial wall thickening of the right main bronchus. Histological and microbiological examinations revealed inflammatory polyps. After 7 months, the inflammatory polyps regressed almost completely without need for removal.

Objective : Appropriate antituberculosis chemotherapy may not prevent occurrence or progression of tracheobronchial stenosis and obstruction in the patients with endobronchial tuberculosis. The effect of corticosteroid treatment combined with antituberculosis chemotherapy was inconclusive. We evaluated prospectively the effect of corticosteroid treatment. Methods : We diagnosed endobronchial tuberculosis by bronchoscopic examination and bronchial biopsy in the patients of tuberculosis within one month of antituberculosis chemotherapy. After randomization, we prescribed isoniazid, rifampin, ethambutol, and pyrazinamide with or without prednisolone 40 mg for 4 weeks. We carried out bronchoscopy in second month and ninth month of treatment. Results : Edematous endobronchial tuberculosis showed significant improvement of bronchial stenosis after corticosteroid treatment(p < 0.05). Corticosteroid treatment did not have advantage of improvement of bronchial stenosis in the patients with infiltrative endobronchial tuberculosis. Conclusion : Corticosteroid is effective in the treatment of bronchial stenosis when endobronchial tuberculosis is edematous type, in the early period of antituberculosis chemotherapy.

Although lipomas are common benign tumors in humans, endobronchial lipomas are quitely rare. Up to date, about 60 cases have been reported in the English literature. But endobronchial lipomas causing middle lobe syndrome were only 4 cases. These benign slow-growing tumors generally occur in the proximal portion of the lobar or segmental bronchi and originate from fatty tissue that is normally present in the bronchial tree. Smoking or chronic inflammation may be important in the pathogenesis of these tumors. Bronchoscopy is the definite diagnostic tool but, in general, open thoracotomy is required for diagnosis and treatment. Here, we present a case of endobronchial lipoma, with a review of the literature.

The lung is the most common site for the metastasis of extrapulmonary malignant tumors. However, endobronchial metastases (EBM) from extrapulmonary malignant tumors are rare. The most common extrathoracic malignancies associated with EBM are the breast, renal and colorectal carcinomas. Lung metastasis from prostate cancer is often encountered but EBM is rare. We report a 74-year old man with endobronchial metastases from prostatic carcinoma presented with cough. The diagnosis of prostatic cancer and the endobronchial metastasis were confirmed by immunohistological staining with the prostate specific antigen. Hormonal therapy (lutenizing hormone releasing hormone agonist) was applied to this patient.
