Vasospastic disorders affecting the lower extremities are unusual entities. Two cases of asymptomatic foot discoloration with lower extremity dependency are presented. In the first case, an elderly gentleman was admitted to the hospital with a contralateral foot infection. His physical exam revealed pulse examination within normal limits and his blood work failed to identify any known causes for vasospasm. His foot infection was successfully treated with sensitivity-directed antibiotics. The second case is that of a young man with a history of quadriplegia secondary to a remote diving accident, who presented with a three-month history of foot discoloration while sitting up in his wheelchair, which resolved with recumbent leg positioning. A review of the possible diagnoses for these patients' presentation is presented herein.
