A 32-year-old woman presented with a three-day history of tenderness and swelling of the left breast. Physical examination revealed a subcutaneous fibrous lesion that was linear and cordlike. The patient was given nonsteroidal antiinflammatory drugs. The lesion and pain both disappeared within six weeks, and the patient has subsequently been well. Mondor's disease is characterized by thrombophlebitis of the subcutaneous veins of the anterolateral thoracoabdominal wall. The condition is three times as frequent in women as in men and is usually benign and self-limited, although it has been associated with breast cancer. Jorge Soler-González, M.D. M.C.
