A 44-year-old male presents to ophthalmology clinic with concern for dry eye and blurry vision for the last three months. In addition, the patient has had blisters on the arms and mouth. Exam is significant for the external photo shown below, mild superficial punctate keratopathy, blisters on the arm that easily rupture, and some mucosal scabbing around the lips and on the oral mucosa. Ocular motility is not significantly impeded. The patient was recently seen in dermatology clinic and a punch biopsy taken from a lesion on the arm revealed IgG deposits in a lattice like pattern with basal cells still attached to the basal membrane.
