Erythema nodosum due to Pasteurella pseudotuberculosis

Area of Science:

• Pediatrics
• Infectious Diseases
• Dermatology

Background:

• Erythema nodosum is an inflammatory condition often with unknown causes.
• Pasteurella pseudotuberculosis is a bacterium not typically associated with erythema nodosum.

Purpose of the Study:

• To investigate the potential link between Pasteurella pseudotuberculosis and erythema nodosum in pediatric cases.
• To highlight an underrecognized etiology for erythema nodosum.

Main Methods:

• Case report of two children presenting with erythema nodosum.
• Diagnostic confirmation using positive agglutination tests for Pasteurella pseudotuberculosis.

Main Results:

• Both pediatric patients developed erythema nodosum.
• Infection with Pasteurella pseudotuberculosis was confirmed via serological testing.
• Clinical presentation did not exhibit typical signs of pseudotuberculosis.

Conclusions:

• Pasteurella pseudotuberculosis can cause erythema nodosum in children.
• The bacterium may be a more frequent cause of erythema nodosum than currently acknowledged.
• Agglutination tests are crucial for diagnosing this association.
