title: [Perianal ulcerations caused by potassium permanganate bath].
abstract: A 73-year-old female patient presented with acute very painful perianal ulcerations. She reported using various ointments and later potassium permanganate baths because of maceration of the rima ani as a manifestation of her psoriasis vulgaris. Suddenly after starting the potassium permanganate baths, necrotic areas developed with then became ulcerated. After excluding the relevant differential diagnostic considerations, we diagnosed ulcerations caused by a caustic burn from potassium permanganate. After stooping potassium permanganate baths and employing modern moist wound therapy, we attained complete healing after 8 months of treatment.
