A 53-year-old woman seeks medical care for superficial erosions and blisters over the skin of her head and trunk. She also has significant involvement of her buccal mucosa, which has made eating difficult. A year earlier, she developed tender sores on the oral mucosa and soft palate of her mouth, which was initially treated as herpes simplex stomatitis. Her condition worsened despite treatment, resulting in the development of eroded areas over her trunk and extremities, with a 10 kg weight loss. Upon further questioning, she denies itching, but she notes that the top layer of her skin could be easily removed when firm horizontal pressure was applied. What is the most likely diagnosis for this patient’s condition?
