Two previous case reports described Actinomyces as a trigger for abdominal inflammatory pseudotumor (1, 2).Objective: To report what we believe is the first case of Actinomyces-induced inflammatory pseudotumor with primary lymph node involvement.Case Report: A 34-year-old woman with a history of systemic lupus erythematosus presented to an outpatient clinic with painful swelling on the left side of the neck, a 7-day history of temperatures up to 39.4 °C, and a 3-day history of cough.
