[Pre-iliac tumor mass syndrome: An atypical rheumatoid nodule].

Rheumatoid arthritis (RA) is a polymorphous chronic inflammatory disease that is common in general population and is responsible for the occurrence of subcutaneous or visceral rheumatoid nodules. Their typical clinical presentations and localizations do not generally pose any diagnostic or therapeutic problem. We report here an atypical fistulized presentation of an unusual iliac rheumatoid nodule in a 65-year-old female patient. The evolution was favorable without recurrence at 6 months after complete surgical resection and appropriate antibiotherapy.
