Mondor's Disease of the Arm Following Breast Cancer Treatment.

Mondor's disease is a rare, peculiar form of superficial thrombophlebitis which mainly affects the subcutaneous veins of the breast, anterior chest wall, neck, axilla, upper limbs and penis. In most cases, it presents with rapid development of a painful subcutaneous cord-like structure that later becomes less painful, but a fibrous band persists. Unfortunately, aetiology and management are not very clear, but it is a self-limiting condition in most cases. We are presenting a rare case of a patient who developed Mondor's disease in the antecubital fossa of the right arm following chemotherapy for breast cancer.
