A case of pulmonary sarcoidosis with endobronchial nodular involvement

Sarcoidosis present as endobronchial lung mass: A rare case report with review of literature

Sarcoidosis is a multisystem granulomatous disorder of unknown etiology, primarily affecting the intrathoracic lymph node and the lung. The endobronchial involvement in sarcoidosis is not uncommon and may appear as nodules, cobblestoning, erythema, or plaque, but presentation as an endobronchial mass has been rarely described. We report here a 50-year-old gentleman who presented with nonproductive cough and dyspnea on exertion. Video bronchoscopy revealed a polypoid mass in the right lower lobe bronchus occluding the posterior basal segment, and bronchial biopsy revealed noncaseating granulomatous inflammation. Bronchoalveolar lavage (BAL) fluid was negative for tuberculosis, fungal infection, and malignancy. Mantoux test was negative, and serum angiotensin-converting enzyme was elevated. The diagnosis of sarcoidosis was made, and the patient was started on an oral corticosteroid. After treatment, the patient showed significant improvement in symptoms. This case report highlights a rare presentation of sarcoidosis as an endobronchial mass lesion. It is important to take a biopsy to differentiate from other common causes of endobronchial mass, such as malignancy and, rarely, tuberculosis. Sarcoidosis should be considered in a differential of the endobronchial mass lesion.

Endobronchial mucosal nodules and actinomycosis in a child with activated phosphatidylinositol 3-kinase delta syndrome (APDS)

In this report, we describe a case of a 5-year-old girl with poor growth and unresolving pneumonia. Bronchoscopy showed numerous endobronchial mucosal nodules, consisting of dense lymphoid infiltrates. Bacterial culture of the nodule biopsy suggested endobronchial actinomycosis. Genetic test confirmed the diagnosis of APDS.

Dry cough in a middle-aged man

Cough is often a distressing feature and may be caused due to varied reasons. A 39-year-old man presented with complaints of cough and had significant pigeon exposure. His chest X-ray revealed mediastinal enlargement and computed tomography chest revealed air trapping and mediastinal lymphadenopathy. Both endobronchial and transbronchial biopsies revealed granulomas. Thus, the patient was diagnosed as a case of sarcoidosis and started on steroids. Hypersensitivity pneumonitis may often mimic sarcoidosis; however, the presence of endobronchial granulomas will diagnose the latter condition.

Multinodule abnormalities of the tracheobronchus: bronchoscopy findings and clinical diagnosis

BACKGROUND AND AIMS

Bronchoscopy is an important method for diagnosing respiratory disease. Multiple tracheobronchial nodules are rarely reported and their causes remain unclear.

OBJECTIVES

The aim of this study was to describe the clinical characteristics of multiple nodule tracheobronchial abnormalities found under bronchoscopy caused by different diseases.

METHODS

Eighty-seven patients with multiple tracheobronchial nodules were enrolled in this study. The characteristics of the multinodule lesions and the patient were diagnosed based on the pathology findings in our hospital. Chest computed tomography images were retrospectively reviewed by pulmonologists and radiologist.

RESULTS

In 55 patients with definite pathological diagnosis, 16 (29%) patients were diagnosed as tuberculosis (TB) granuloma; 23 (41.8%) cases were diagnosed as malignant disease; 12 (21.8%) cases were diagnosed as tracheobronchopathia osteochondroplastica; 2 (3.6%) cases were diagnosed as sarcoidosis; and one case (1.8%) was diagnosed as lymphoma and one case (1.8%) as fungal infection. There were 32 cases of chronic inflammation. There was no relationship between nodule distribution and the pathological diagnosis. Malignant nodules usually smaller with a pale outlook, while nodules with larger size and smooth and intact mucosa usually turn out to be granuloma of unknown reason.

CONCLUSION

The major causes of mutinodule lesions observed using bronchoscopy are tumor and TB. The presence of multiple endotracheobronchial nodules suggest that pulmonary lesion is present, and biopsy should be performed. Malignant nodules can be diagnosed by appearance and biopsy. Pathology results of TB, sarcoidosis and fungal infection can turn out to be granuloma of unknown reason. Further diagnosis needs other clinical materials.
