title: The effect of tacrolimus on lower extremity ulcers: a case study and review of the literature.
abstract: Tacrolimus, a calcineurin inhibitor, has become an increasingly valuable tool in the treatment of dermatological disorders during the last few years. However, its effect on wound healing is still under investigation and remains the subject of safety concerns. A 75-year old woman with lichen planus, diabetes mellitus, and a foot ulcer was prescribed tacrolimus for the treatment of her lichen planus. After starting the treatment, her ulcer healed and the medication was discontinued. Shortly thereafter, re-ulceration occurred, treatment was re-introduced, and the wound continued to heal until treatment was discontinued. When the third course of tacrolimus was prescribed, the ulcer started healing again but a diagnosis of osteomyelitis necessitated surgical intervention. A review of the literature suggests that tacrolimus does not adversely affect healing in vivo or in vitro and may facilitate healing lower extremity skin ulcers, especially those of inflammatory origin. Studies are needed to clarify which lower extremity wounds would improve with tacrolimus.
