For right breast cancer, 42-year-old female underwent total right mastectomy and breast reconstruction with abdominal flaps in May 20XX, and two revisions in October 20XX+1 and November 20XX+2. In January 20XX+1, erythema appeared in part of the surgical scar of the right breast and showed a gradual tendency to expand, but no treatment intervention was provided. The edematous erythema invading the entire suture line of the right breast and hyperpigmentation with scaling around the erythema were diagnosed as nummular eczema, and topical steroid treatment was started. It is important for dermatologists to recognize that nummular eczema may occur after breast reconstruction surgery and to encourage moisturizing and early therapeutic intervention.
