Lyme disease patients with POTS can sometimes present with discolored extremities, like this patient with purple toes. What is it?
Most patients are aware of Raynauds syndrome which is characterized by a paroxysmal white-blue-red or just white and blue discoloration of the fingers and toes. The attacks are induced usually by cold or stress. They last an average of 20 minutes but can also persist for hours.
This patient suffers from acrocyanosis. A less common condition than Raynauds syndrome. It's characterized by painless, bluish-red symmetrical discolorations of the hands, feet and knees. Acrocyanosis of the lower extremities can occur in patients with Postural Orthostatic Tachycardia (POTS).
