Case 2

A 40-year-old man presents to the dermatology clinic complaining of extremely painful sores on his back, neck, and chest.

He developed hoarseness and had difficulty swallowing, for which he was evaluated by an otolaryngologist. Physical examination of the patient’s skin reveals numerous painful, flaccid blisters with bloody erosions and a positive Nikolsky sign. The patient denies pruritus and has no lesions on his palms or soles.
