Case presentation
We present three Chinese male patients aged between 50 to 60 years old, with similar complaints of recurrent episodes of vesicles, blisters, erosion/ulcers predominantly on sun-exposed areas. They were diagnosed as having PCT after a clinical investigation. Of note, all patients had a history of alcohol abuse with or without apparent liver function damage. Treatment includes hydroxychloroquine and alcohol discontinuation. Patients showed marked improvement in skin lesions with no relapse.
