Actinomycotic abscess of the thyroid gland in an infant

Area of Science:

• Endocrinology
• Pediatric Surgery
• Infectious Diseases

Background:

• Actinomycosis is a bacterial infection characterized by abscess formation.
• Thyroid gland involvement by actinomycosis is exceptionally rare, particularly in pediatric populations.

Observation:

• This case report presents the second documented instance of actinomycotic abscess of the thyroid gland in a child, occurring at 18 months of age.
• The typical route of infection, via preformed pathways from the upper aerodigestive tract like a piriform sinus fistula, was not evident in this case or prior pediatric reports.

Findings:

• The study highlights the rarity of pediatric thyroid actinomycosis.
• It questions the routine use of invasive diagnostic procedures like barium swallow in initial pediatric presentations due to their difficulty in young children.

Implications:

• This case contributes to the limited literature on pediatric thyroid actinomycosis.
• It suggests a conservative approach to diagnostic work-up for non-recurrent cases in infants and young children, reserving more intensive investigations for specific clinical scenarios.
