The excoriated vesicles were healed with depressed scars. They had no previous history of intense abdominal pain, seizure, or psychiatric disorder. Urinary porphyrins were analyzed by High Performance Liquid Chromatography (HPLC). The level of coproporphyrin III was detected to be higher than the uroporphyrin level. Fluorescence emission scanning of both patients' plasma was performed and demonstrated typical emission peak at 626 nm, that confirmed the diagnosis of variegate porphyria.Mahidol UniversityMedicineArticleSCOPUS
