Abstract
Mondor's disease is a relatively rare benign disease which is characterized by thrombophlebitis of the subcutaneous vein in the anterior chest wall. It involves a painful subcutaneous cord caused by breast surgery, trauma, or infection. We report a rare case of Mondor's disease after an operation for gynecomastia. A 74-year-old man who underwent surgery for gynecomastia, complained of a painful groove in the chest for one week postoperatively. Physical examination revealed a longitudinal groove from the left breast to the upper abdomen. In an imaging study, a subcutaneous cord was observed in the induration. We diagnosed it as Mondor's disease that developed with the resection of gynecomastia. Observation was carried out, and the subcutaneous cord disappeared spontaneously in about one month.
