<p>A 72-year-old woman with chronic myeloid leukemia with T315I mutation in breakpoint cluster region-abelson (BCR-ABL) was treated with ponatinib.

She was referred to our department for salvage of the right lower extremity. We performed a foot bypass and multidisciplinary treatment of the wound, and achieved epithelialization in about 1 month.
