Carcinomatous Polyarthritis

Polyarthritis can rarely (<2%) be the presenting manifestation of an occult malignancy. The association of polyarthritis and malignancy is suggested by:

  • A close temporal relationship between the onset of a seronegative arthritis and the diagnosis of malignancy.

  • Improvement of the arthritis with treatment of the underlying cancer.

  • Recurrence of the arthritis with tumor recurrence.

Carcinomatous polyarthritis should be strongly suspected in a patient with the following features:

  • Explosive onset of an asymmetric oligoarthritis or polyarthritis

  • Late age of onset

  • Predominant lower extremity involvement

Radiographs show no periosteal reaction. Note that polymyalgia rheumatica-like symptoms unresponsive to prednisone have also been described as a presentation of various malignancies.
