Mondor's disease in a patient previously treated for breast carcinoma in situ: a case report.

Mondor's disease is a thrombophlebitis that affects mainly the superficial veins of the breast. The aetiology of Mondor's disease is multifaceted and there are reports in the literature of an association between Mondor's disease and breast cancer. This disease occurs more commonly in women than men, mainly in the third and fourth decades of life, leading to a spontaneous remission in most cases. We report a case of a 45-year-old female patient that had been treated for breast carcinoma in situ.
