Postbiopsy Mondor disease as an early indicator of elevated thrombophlebitis risk: A case report.

Mondor disease (MD) is a rare, benign condition marked by thrombophlebitis of superficial veins of the breast or anterior chest wall. While it is idiopathic in most cases, it can sometimes occur secondary to an underlying cause. This case report describes a 51-year-old female, who developed MD approximately 7 weeks after undergoing a breast biopsy. Despite no prior history of venous thromboembolism, the patient also developed deep and superficial venous thromboses a few months following her diagnosis of MD. This case highlights the importance of the need to search for potential predisposing factors for venous thromboembolism once the diagnosis of MD has been established.
