Refractory eczematous dermatitis associated with retained suture material.

We present a patient who developed a cutaneous-id reaction and eczematous dermatitis related to a residual Prolene suture following excision of dermatofibrosarcoma protuberans. Following a wider excision of the site, with removal of the retained suture material, the patient's symptoms dramatically improved. Although this reaction is rare, retained sutures should be considered a possible cause of a postoperative eczematous dermatitis that does not respond to standard therapies.
