We present the clinical and serological characteristics of three patients with rhupus.

The 3 patients with rhupus presented ACR criteria for SLE as well as for RA, ANA positive with a titer of 1/100 in all patients, and positive anti-DNA in 2 of the 3 patients, with the predominance of symmetrical polyarthritis.

We found anti-CCP positivity and rheumatoid factor positivity and high titers in all patients, positive anti- anti-SSA in one patient, and positive anti- anti-Sm in one patient.

Renal and liver function tests were normal in all patients.

The 3 patients achieved clinical remission with DMARD treatment.
