case_images: We found a skin lesion on the patient's lower back. It was a large erythema with a small amount of exudate. There was no apparent fistula, but an inflammatory state was suspected. This lesion was diagnosed as psoriasis vulgaris by a dermatologist, which was severe but improved with topical medication.
