Snapshot A 40-year-old woman with a past medical history of rheumatoid arthritis presents to the inpatient dermatology consult service with 3 ulcers on her abdomen. A few days ago, she underwent a laparoscopic cholecystectomy and had been recovering in the hospital. However, while changing her dressing, the team noticed that she had 3 growing ulcers at the sites of incisions. On physical exam, she has 3 sharply demarcated ulcers with violaceous raised borders, all on a purulent base. Concerned for an inflammatory process, the dermatology team prescribes systemic steroids.
