A 38-year-old woman visited her doctor about itchy, raised spots that developed on her fingers 5 days prior. On examination, multiple vesicles of varying sizes, forming bullae on the distal fingers of both hands, were seen. She was not on any medications and had no recent history of trauma. She had asthma and a history of eczema in childhood. The patient appeared well and displayed no systemic symptoms. Do you know what’s on her fingers?
