Mondor's Disease: A Rare Cause of Chest Pain.

INTRODUCTION: Chest pain is a very frequent reason for seeking medical care. When there is no obvious cause, patients are sometimes subjected to tests and treatments that may be unnecessary and potentially harmful. Mondor's disease is a rare but usually benign and self-limited entity characterized by thrombophlebitis in a specific region. CASE REPORT: We report the clinical case of a 51-year-old man admitted to the emergency department with a 24-hour history of left chest pain with no other symptoms. Physical examination revealed a palpable subcutaneous cord-like structure that ultrasound confirmed to be thrombophlebitis of a superficial vein in the mammary region. Secondary causes were ruled out, and the condition resolved with ibuprofen and the application of local ice. DISCUSSION: Mondor's disease can be associated with neoplasms, trauma or hyperviscosity states, but it is mostly idiopathic. Usually, it resolves completely in 4-8 weeks without specific treatment. Because this infrequent diagnosis mainly relies on clinical findings, it is important that clinicians can recognize the syndrome. LEARNING POINTS: Mondor's disease is a rare but benign disease, with no proof that specific treatment, such as anticoagulation, is beneficial.It may be secondary to underlying disease as malignancy, vasculitis, trauma or hyperviscosity states, which should be excluded.Treatment in the majority of the cases is symptomatic, but if it is secondary Mondor's disease, the underlying problem should be investigated. Physicians should be aware of this condition in order to address patient concerns and avoid unnecessary treatments or investigations. © EFIM 2020.
