Interferon-βCutaneous ulcerations and exacerbation ofpsoriasis: 8 case reports
Eight patients with multiple sclerosis received SC injectionswith recombinant interferon-β [‘Betaseron’] 32 × 106 IU/day.Six patients developed ulcerations at the injection sites, 1patient had painful nodules that did not ulcerate, and 1 patientexperienced a pustular flare of her usually quiescent psoriasis.
The onset of the patients’ symptoms occurred 6–19 weeksafter beginning interferon-β. All 7 patients with injection sitereactions experienced pain after the injection, and 2 patientsexperienced severe pruritus. Interferon-β therapy wasdiscontinued when the reactions were reported. However, 1patient did continue interferon-β therapy without any furtherproblems.
The ulcerations were sharply bordered and initially therewas an overlying black eschar. The results of biopsy specimensshowed a mixed perivascular infiltrate. All of the ulcers healedwith routine wound care, and the older lesions showedevidence of scarring. No evidence of an infectious cause for theskin disorders was found.Webster GF, et al.
