Pediatric actinomycosis of the head and neck
1Department of Otolaryngology, Baylor College of Medicine, Houston, Texas 77030.
Abstract:
Actinomycosis is a rare soft tissue infection caused by a gram-positive, anaerobic bacteria. It is seen only approximately once a year in major medical centers, and is rarer still in the pediatric population. About 50% of all cases of actinomycosis involve the head and neck. The organism is very difficult to isolate in culture and the differential diagnosis is extensive, prompting one reviewer to name actinomycosis the "masquerader" of the head and neck. We review three cases of actinomycosis over the past ten years (1981-1990) at Texas Children's Hospital, Houston, Texas.
Insights
Actinomycosis, a rare soft tissue infection, often affects the head and neck. This review examines three pediatric cases, highlighting diagnostic challenges of this difficult-to-culture bacterial infection.
Area of Science:
- Medical microbiology
- Infectious diseases
- Pediatric medicine
Background:
- Actinomycosis is a rare infection caused by gram-positive, anaerobic bacteria, infrequently encountered in major medical centers.
- Pediatric cases are exceptionally rare, with approximately 50% of all actinomycosis infections occurring in the head and neck region.
- The causative organism's difficulty in culture and broad differential diagnosis lead to its classification as a diagnostic "masquerader."
Observation:
- This study reviews three cases of actinomycosis diagnosed over a ten-year period (1981-1990) at Texas Children's Hospital.
- All three cases involved the head and neck region, consistent with the known predilection of the infection.
- The clinical presentations likely posed diagnostic challenges due to the rarity and varied manifestations of actinomycosis.
Findings:
- The review highlights the challenges in diagnosing actinomycosis, particularly in pediatric patients.
- The difficulty in isolating the bacteria underscores the need for high clinical suspicion.
- Case review supports actinomycosis as a significant differential diagnosis for pediatric head and neck masses.
Implications:
- Increased awareness of actinomycosis in pediatric head and neck infections is warranted.
- Diagnostic strategies may need to incorporate clinical suspicion alongside microbiological data.
- Further research into improved diagnostic methods for actinomycosis could benefit patient outcomes.
