Congenital bronchial atresia is a rare pulmonary abnormality characterized by the disrupted communication between the central and the peripheral bronchus and is typically asymptomatic. Although it can be symptomatic especially when infections occur in the involved areas, fungal infections are rare complications in patients with bronchial atresia. We report a case of congenital bronchial atresia complicated by a fungal infection.

Postmortem examination of the two spotted deer died during March 2018 revealed presence of extensive areas of caseous and abscess-like lesions in the lungs and adjoining lymph nodes with accumulated pus discharges in the pleural cavity (Figure 1).The pus samples from the pleural cavity were sampled aseptically in sterile screw-capped containers for microbiological and molecular examination.

Enterococci are rarely considered pulmonary pathogens; they are usually regarded as colonizers of the airway. The authors present the case of a previously healthy male adolescent, with complaints of fatigue and chest pain, who was diagnosed with Enterococcus faecalis-associated acute primary lung abscess.

Tuberculosis is caused by various strains of Mycobacteria usually Mycobacterium tuberculosis. It is spread through the air when people who have an active TB infection cough, sneeze, or otherwise transmit respiratory fluids through the air . In 15-20% of active cases, the infection spreads outside the lungs, causing other kinds of TB. These are collectively denoted as “Extra pulmonary Tuberculosis” extra pulmonary TB occurs more commonly in immune suppressed persons and young children. This study was conducted in tertiary care hospital, Jamnagar.

Bronchial Adenomas Bronchial adenomas (80% are central) are slow-growing endobronchial lesions; they represent 50% of all benign pulmonary neoplasms. About 80–90% are carcinoids, 10–15% are adenocystic tumors (or cylindromas), and 2–3% are mucoepidermoid tumors. Adenomas present in patients 15–60 years old (average age 45) as endobronchial lesions and are often symptomatic for several years. Patients may have a chronic cough, recurrent hemoptysis, or obstruction with atelectasis, lobar collapse, or pneumonitis and abscess formation.

Approach to the Patient: Hemoptysis The history is extremely valuable. Hemoptysis that is described as bloodstreaking of mucopurulent or purulent sputum often suggests bronchitis. Chronic production of sputum with a recent change in quantity or appearance favors an acute exacerbation of chronic bronchitis. Fever or chills accompanying bloodstreaked purulent sputum suggests pneumonia, whereas a putrid smell to the sputum raises the possibility of lung abscess. When sputum production has been chronic and copious, the diagnosis of bronchiectasis should be considered.
