ABSTRACT
BACKGROUND: Acute Q fever is asymptomatic in 60% of the patients, while the reminder may present with fever, pneumoniae, and hepatitis. Skin manifestations are uncommon including transient punctiform rashes, purpuric, or maculopapular eruptions. Erythema nodosum have seldom been reported. CASE PRESENTATION: A 37-year-old female presented with fever for 1 month and skin lesions consists of erythematous painful nodule of the legs. Serological testing for Coxiella burnetii was positive. Treatment consisted with doxycycline for 2 weeks. Evolution was favorable. The patient completely recovered and had no evidence of skin lesion 1 month later. CONCLUSION: Because of its nonspecific clinical presentation, Q fever with erythema nodosum is probably underestimated. Q fever should be evocated when facing unexplained erythema nodosum even if there is not other typical clinical manifestation of Q fever.
