ABSTRACT

We present the case of a six-year-old boy who was attended at primary care center due to fever and two scabby lesions, one on the scalp and the other on the trunk, as well as cervical-occipital lymphadenopathies, after a tick bite 24 hours ago. The initial diagnosis is rickettsiosis, specifically of TIBOLA, which, after the appearance of a generalized palmar and plantar rash, was changed to Mediterranean spotted fever (MBF). However, serology for Rickettsia conorii was negative but the eschar PCR (polymerase chain reaction) was positive for Rickettsia sibirica, the most common producer of FBM associated with lymphangitis or "like" FBM. After treatment with azithromycin, fever disappeared within 48 hours and more progressive, of skin lesions and lymphadenopathy over 20 days later.
