A 50-year-old woman presented to our dermatology clinic with an exquisitely tender, nonhealing lesion on the left leg of 2 weeks' duration that began as a small red-purplish spot. She applied a triple antibiotic ointment and wrapped the area with gauze daily but reported that it continued to enlarge and darken in color before forming a "scab." She noted occasional seropurulent discharge and denied any trauma or new exposures to the area. She was seen at a local emergency department 3 days prior to presentation and was prescribed oral clindamycin for suspected cellulitis, but she denied any improvement with the initiation of antibiotics. Her medical history was notable for obesity, depression, hypothyroidism, and liver disease secondary to alcohol use disorder. She reported that she drank a pint of vodka daily. Her medications included pantoprazole, spironolactone, bumetanide, citalopram, levothyroxine, naltrexone, tramadol, and a multivitamin. Physical examination revealed violaceous mottling with areas of superficial erythema and ulceration with necrotic eschars on the proximal left thigh that were extremely painful. A biopsy was obtained for confirmation of diagnosis, but the patient died before the results were returned.
