Pulseless hematochezia: Takayasu's arteritis associated with ulcerative colitis.

A 36-year-old woman with ulcerative colitis presented with fever, chest and back pain, and fatigue sensation of the arm. Her upper limb pulses were absent. Angiography showed multiple aneurysms of the aorta and its branches, consistent with Takayasu's arteritis. She showed HLA-B35 but no B52, which is the typical haplotype among the coexistence cases of both diseases. Prednisolone was effective. The possible pathogenic association of the disorders is discussed.
