[Coxiella burnetii osteoarthritis].

A case of a 25-year-old female characterized by febrile osteoarthritis and arthromyalgias as the only clinical manifestation of a Q fever is discussed. Analytical data were compatible with those of an acute inflammation and serologic findings reached diagnostic levels. Response to Doxycycline treatment was totally satisfactory. Even though associated arthromyalgias are described in some cases of Q fever as well as sporadic cases of osteoarthal infection due to Coxiella burnetii, there are no oligosymptomatic cases published as the one discussed. Some physiopathologic considerations referred to this peculiar onset are suggested.
