DISCUSSIONThe cutaneous side effects attributed to IFN-o~ are numerous. Injection site erythema and induration are the most common cutaneous reactions. 1 Alopecia, exacerbation of herpes labialis, pruritus, punctate telangiectases on the extremities and trunk, onset of psoriasis, flaring of preexisting psoriasis, eosinophilic fasciitis, paraneoplastic pemphigus, and anasarca were listed in a recent review. 3 In addition, injection site ulcerations that showed vascular proliferation and fibroplasia below areas of ulceration have been described. 3 Injection site ulcerations have also been reported after subcutaneous administration of IFN-13-1b. Biopsy specimens revealed a perivascular lymphohistiocytic infiltrate and thrombosis of deeper vessels, but no evidence of leukocytoclastic vasculitis. 4 Other injection-site reactions to IFN-c~ include painful nodules with vesiculation 5 and localized induration with necrosis. 6 Histologic examination of the nodules revealed a subcorneal vesicle containing neutrophils, epidermal spongiosis, vacuolar basal layer change, and a perivascular lymphocytic infiltrate (thought to be consistent with a fixed drug eruption), 5 whereas the induration showed thrombosis of the venous vessels in the dermis and subcutaneous fat. 6 Other reported cutaneous reactions include contact allergy, 7 psoriatic arthritis, 8 mouth ulcers, 2 xerostomia, 9 a bullous eruption, 1 and exacerbation of lichen planus, n A case report of a" vascufitic lesion"(not confirmed by biopsy) on a patient's finger that resulted in sloughing of the fingertip 1 week after intramuscular IFN-a therapy for testicular cancer has been published12; however, to our knowledge, no reports of injection site vascufitis have been made.A strong association between essential mixed cryoglobulinemia and hepatitis C exists. According to a recent report, the majority of patients with essential mixed cryoglobulinemia also have hepatitis C. 13 Essential mixed cryoglobulinemia is characterized by vasculitis, arthralgias, malaise, and often glomerulonephritis. 2 Histologically, the typical findings of leukocytoclastic vasculitis are present, sometimes in conjunction with hyaline thrombi in dermal vessels. 13 IFN-a is efficacious for hepatitis C-associated cryoglobulinemia, with improvement reported in aminotransferase enzyme levels 14 and clearing of cutaneous vasculitis. 2 Although our patient could have vasculitis resulting from hepatitis C-associated cryoglobulinemia, several components of the presentation argue against this. First, the predominance of lesions on the thighs is uncharacteristic of vasculitis associated with essential mixed cryoglobulinemia, in which there is usually more distal predom-
