Introduction:
Actinomycosis is a rare infectious disease caused by Gram-positive bacteria. The most common species is Actinomyces israelii. Among its forms of presentation, the thoracic is the least frequent.
Case Presentation:
We report two patients with thoracic actinomycosis, 8 and 13 years old, from different geographical areas of Peru. The first case had empyema necessitans and the second, lung consolidation and recurrent hemoptysis. Both had a certain degree of difficulty in their diagnosis but responded favorably to antibiotics and surgical treatment. The diagnosis was based on the histopathological study. However, we were not able to ascertain the species of actinomyces.
Conclusion:
Thoracic actinomycosis is rare in children and presents as a parenchymal lesion with possible fistulization to the chest wall. This article is one of the few in the Peruvian literature, constituting a contribution to the knowledge of the disease and its management in pediatrics.
Insights
Thoracic actinomycosis, a rare bacterial infection, presents uniquely in children. Early diagnosis and treatment with antibiotics and surgery are crucial for favorable outcomes in pediatric cases.
Area of Science:
- Infectious Diseases
- Pediatric Medicine
- Bacteriology
Background:
- Actinomycosis is a rare infection caused by Gram-positive bacteria, most commonly Actinomyces israelii.
- Thoracic actinomycosis is an infrequent manifestation of this disease.
- Pediatric thoracic actinomycosis is exceptionally rare.
Observation:
- This report details two pediatric cases of thoracic actinomycosis from Peru, aged 8 and 13.
- One patient presented with empyema necessitans, while the other had lung consolidation and recurrent hemoptysis.
- Diagnostic challenges were encountered in both cases, highlighting the need for thorough evaluation.
Findings:
- Both patients received a favorable response to a combination of antibiotic therapy and surgical intervention.
- Histopathological examination was key to diagnosis, though specific Actinomyces species identification was not achieved.
- Thoracic actinomycosis in children can manifest as parenchymal lesions potentially leading to chest wall fistulization.
Implications:
- This case series contributes valuable data to the limited Peruvian literature on pediatric thoracic actinomycosis.
- It underscores the importance of considering actinomycosis in the differential diagnosis of pediatric chest conditions.
- Effective management involves a multidisciplinary approach including antibiotics and surgery for improved patient outcomes.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...
