Mondor's disease of the breast--three cases report.

Mondor's disease is a rare and relatively little known clinical entity. Clinical features include sudden development of localized pain in the breast, followed by visible and papable, tender, cordlike, branching cutaneous grooves. It involves superficial thrombophlebitis of the thoracoepigastric or lateral thoracic vein occurring mostly in middle-age women. The etiology of Mondor's disease is unknown, and it may be related to trauma, operation, infection, bandaging, or tight clothes. The mammogram of most cases showed no abnormality, but the ultrasonography revealed hyperechoic cordlike pattern in the lesions. The symptomatic treatment is required and surgery will be indicated when it is associated with malignancy or severe painful cord due to pain and traction. It usually resolves over a period of 2 to 8 weeks. We report three cases of Mondor's disease and that we believe to be the first reported cases in Taiwan.
