CHIEF COMPLAINT: lower extremity swelling, pruritis, and pain
CLINICAL HISTORY: A 67-year-old Caucasian male presented to the clinic with a chief complaint of lower extremity swelling, pruritus, and pain. He also complained of discoloration of his lower extremities, right arm, and axillae, stating that one of his feet was “turning black”. Over a one-month duration, the patient noticed dark patches developing on his lower extremities, right upper extremity, and axillae. There was associated edema in his lower extremities accompanied by pain and pruritus. The patient visited urgent care, an emergency room, and his podiatrist for the chief complaint. Laboratory studies, radiographs, and an EKG were all found to be normal. The patient’s past medical history included renal transplantation in October 2010, and was maintained on mycophenolate mofetil 1g PO BID, tacrolimus 3mg PO BID, and prednisone 10 mg PO daily. Pertinent family medical history included a brother who was deceased due to malignant melanoma found in the axillae.
