Synopsis

Invasion of the lymph node by neutrophils resulting in rapid swelling, capsular distension, edema, and eventual tissue necrosis. There may be overlying erythema of the skin and lymph node drainage.

Physical exam findings reveal tender lymphadenopathy, overlying erythema, or possible drainage from the affected lymph node. Often, patients will present with persistent symptoms despite antibiotic therapy, indicating the need for further testing for atypical causes or for lymph node drainage.

Suppurative lymphadenitis is a common complication of strep pharyngitis, and the most common bacterial causes are Staphylococcus aureus, Streptococcus pyogenes, Yersinia, Bartonella henselae, tuberculosis, and lymphogranuloma venereum.
