Gemcitabine is a nucleoside analogue used for treatment of multiple cancers. Recent reports describe small to medium vessel vasculitis as a rare complication of therapy. We report a case of significant large vessel vasculitis presenting as fever of unknown origin in a patient treated adjuvantly with docetaxel and gemcitabine for uterine leiomyosarcoma.The patient presented after her first and second exposure to chemotherapy with fever of unknown origin and worsening subsequent chest and neck discomfort. Extensive workup revealed radiographic and laboratory evidence of aortic vasculitis. We initiated treatment with high-dose corticosteroids, and the patient's condition resolved without complication over the next several weeks.To our knowledge, this represents the first case of gemcitabine-induced large vessel vasculitis which presented in our case as fever of unknown origin. Awareness of this potential complication is essential as discontinuing the inciting drug and initiating corticosteroid treatment can be life-saving.

Gemcitabine is a nucleoside analogue used widely across haemato-oncology. Side effects are generally predictable, and typically consist of cytopenia, nausea, and infection. As the present case clearly demonstrates, gemcitabine is in rare cases associated with life-threatening large vessel vasculitis, which can involve the aorta. It is important to consider gemcitabine-induced vasculitis in non-specifically unwell patients with raised inflammatory markers and fever of unknown origin, with or without signs of vascular compromise. Early recognition, cessation of gemcitabine therapy, and high-dose steroids are critical for a good outcome. PET CT is valuable to diagnose large vessel vasculitis and monitor treatment response.

Vasculitis is an inflammation that can present as acute or chronic in nature, which causes changes in the walls of blood vessels, including thickening, weakening, narrowing and scarring. Gemcitabine, an antimetabolite chemotherapeutic agent, is generally well tolerated with a favorable side effect profile. However, there is increasing evidence that it is associated with vasculitis, which can affect small and large vessels. In this case report, we report a patient who has experienced fever with severe tenderness over right carotid artery, which occurred on the fifth day after the administration of gemcitabine. The exact mechanism of gemcitabine-induced vasculitis is unknown but cessation of gemcitabine and initiation of anti-inflammatory treatment appears to aid in the resolution of the clinical syndrome.
