Abstract
A 49-year-old man diagnosed with genotype 1 hepatitis C, CD5-positive marginal zone lymphoma, and mixed cryoglobulinemia type II developed skin ulcers and necrosis in his right foot. He was treated with amlodipine, corticosteroids, plasmapheresis, alprostadil, rituximab, and cyclophosphamide without a satisfactory response. For this reason, he required a partial amputation of the second, third, and fifth fingers of the right foot. To prevent ulcer deterioration of the first finger, bosentan was initiated. After 10 months of treatment, the ulcer completely healed and no adverse effects were experienced by the patient.
