A 14-year-old girl with a sudden arm swelling after axillary depilatory wax.

Takayasu's arteritis is a systemic vasculitis predominantly affecting the aorta and its major branches. We report a 14-year-old girl in whom incidentally a deep upper limb vein thrombosis was found. She was referred to the emergency unit due to swelling and intermittent cyanosis of the right arm following an axillary depilatory wax. High-resolution echo colour Doppler ultrasonography showed a deep vein thrombosis with thickening of the proximal common carotids. A diagnosis of type IIb Takayasu's arteritis was made. The patient's history revealed fatigue, myalgia and headache. Immunosuppressive treatment and anticoagulation were introduced with a rapid and sustained improvement.
