Allergic Contact Dermatitis at the Incision Site After Surgical Casting.

Allergic contact dermatitis (ACD) may develop after postoperative casting. A 52-year-old male patient presented to our outpatient clinic complaining of pain, swelling, and bruising in his left forearm following a simple fall. An X-ray revealed a fracture of the left ulnar shaft. The patient, whose general condition and follow-up findings were good, was discharged on the first postoperative day with appropriate recommendations and instructed to return for a follow-up visit on the 15th day. Consequently, the possibility of ACD should be considered when using materials for casting, and it should be noted that even the casting cotton used can cause this condition.
