Example Cases

1. My diagnosis was multiforme erythema and I treated her with cetirizin and dermocorticoids. She went to ER this WE because of pain and had a blood sample which was normal. Today (picture upper), she confessed having put some argile on her shoulder few days ago because of articular pain... I will wait and make a biopsy if the things don't get well in 3 days (if she agrees)
