Summary
A rare case of endobronchial actinomycosis, mimicking tuberculosis, was diagnosed in a 70-year-old woman. Prompt treatment with penicillin led to a positive clinical response, highlighting the importance of considering this infection.
Area of Science:
- Pulmonology
- Infectious Diseases
- Medical Microbiology
Background:
- Endobronchial lesions can present with diverse etiologies, often mimicking infectious processes like tuberculosis.
- Differential diagnosis of airway obstruction is crucial for effective patient management.
Observation:
- A 70-year-old female presented with exertional dyspnea and cough.
- Fiberoptic bronchoscopy identified an endobronchial polypoid lesion causing bronchial stenosis.
- The lesion's appearance was highly suggestive of endobronchial tuberculosis.
Findings:
- Histologic examination of the biopsy confirmed Actinomyces infection.
- The patient demonstrated a significant clinical improvement following intravenous penicillin therapy.
Implications:
- Primary endobronchial actinomycosis should be considered in the differential diagnosis of endobronchial lesions.
- This is particularly relevant in regions where endobronchial tuberculosis is prevalent, such as Korea.
- Early diagnosis and appropriate antibiotic treatment are key for favorable outcomes.
