Summary
This case study highlights an unusual Actinomyces meyeri infection presenting as a leg abscess and lung lesion, bypassing typical head and neck sites. It underscores the importance of considering rare presentations and species in Actinomycosis diagnosis.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Dermatology
Background:
- Actinomycosis infections commonly affect the cervico-facial region (50-65% of cases).
- Actinomyces israeli is the most frequent pathogen, identified in 85% of cases.
- Extra-cervical cutaneous lesions are rare manifestations of Actinomycosis.
Observation:
- A case of Actinomyces meyeri infection presented with a leg abscess and pulmonary lesion.
- Notably, there was no cervico-facial involvement, but chronic parodontitis was present.
- Capnocytophaga sp. was co-isolated from the leg abscess.
Findings:
- This represents a rare instance of extracervical Actinomycosis due to Actinomyces meyeri.
- Only 17 previous cases of Actinomyces meyeri infection have been documented.
- The findings suggest a potential mechanism involving buccodental origin, inhalation leading to pulmonary lesions, and subsequent septicemic dissemination.
Implications:
- This case expands the understanding of Actinomycosis's clinical spectrum and potential origins.
- It emphasizes the need for considering rare pathogens and unusual localizations in diagnosing Actinomycosis.
- Further research into the pathogenesis of extracervical Actinomycosis is warranted.
