A man in his 80s with a pacemaker; a history of congestive heart failure, coronary artery disease, atrial fibrillation, transient ischemic attack, and Parkinson disease; and dependence in all activities of daily living presented to the dermatology department with a 4-month history of new-onset persistent facial eruption. He denied a history of facial flushing. The patient was initially treated for rosacea at an outside hospital with topical 1% metronidazole cream for 1 month without improvement and developed acute facial purpura after 1 day of treatment with oral doxycycline, which was discontinued. Because of the eruption’s rapid onset and violaceous appearance, as well as empirical treatment failure, the patient was referred for further evaluation. On examination, the patient had asymmetric, centrofacial, erythematous-violaceous indurated telangiectatic and ecchymotic plaques over a phymatous background (Figure, A). A series of punch biopsies were performed (Figure, B-D).
