Contributed by Misha Rosenbach, MD

A 72-year-old female with congestive heart failure, started on furosemide six weeks ago, presents for evaluation of an extremely pruritic, progressive rash for the past two weeks on her trunk and extremities.

  • Her daughter is concerned that she is now developing tense blisters over the rash.
  • She reports the rash was biopsied by a dermatologist three days ago, who mentioned that she had a “positive DIF” and normal labs (complete blood cell count with differential, renal and liver function tests, as well as a bacterial culture of the base of a blister).
