To the Editor.—
We would like to report a case of cutaneous necrotizing vasculitis that was presumably induced by an allergic reaction to furosemide.
Report of a Case.—
A 72-year-old white man with a past history of an anterior myocardial infarction, congestive heart failure, pacemaker insertion, mild renal insufficiency, and duodenal ulcer was referred to University Hospitals from a nursing home with a four-day history of purpuric skin lesions and blood-tinged sputum. His medications at the time of admission included daily doses of furosemide (40 mg) for at least the past five months and digoxin (0.25 mg).On admission, physical examination revealed bibasilar pulmonary rales, a liver palpable 8 cm below the right costal margin, edema of both legs (3+ ), and a functioning cardiac pacemaker. The patient was responsive, but demented, with positive grasp and snout reflexes. The left pupil was nonreactive with vertical nystagmus noted on horizontal gaze. Bruits
