Mondor's Disease of the Breast in a Nigerian Woman Previously Treated for Invasive Ductal Carcinoma in the Contralateral Breast: A Case Report

Mondor's disease is a self-limiting sclerosing angitis mostly affecting the superficial veins of the breast and chest wall. It is seldom diagnosed, and its etiology and epidemiology are speculative. However, numerous predisposing factors including breast cancer have been postulated. In Nigerian literature, only two cases have been documented to the best of our knowledge. This report is aimed at reminding breast specialists to include it as a diagnostic consideration in patients presenting with a breast lump in the appropriate clinical setting. Its imaging features are also highlighted because it may be incorrectly overlooked as mere ductal dilatation. We present the case of a 60-year-old woman who complained of a painful cordlike lesion in her right breast. Mondor's disease was diagnosed based on the clinical and radiological findings. She had also been previously treated for invasive ductal breast carcinoma in the contralateral breast. Mondor's disease is usually a benign entity, which may resolve spontaneously. On the other hand, it may also be the sole presenting symptom or clue of a breast malignancy; hence, a need for increased awareness.
