The development of antinuclear antibodies after long-term use of anti-TNF therapy has been reported by several authors. The occurrence of lymphoproliferative neoplasms and, less commonly, solid tumors has also been reported. We present a case ofsimultaneous development of antinuclear antibodies and solid tumor in a patient with spondyloarthritis while on infliximab therapy. The implications and possible correlations with a solid tumor occurrence are reviewed and discussed
