770 Mondor's Disease: A Rare Presentation of Inflammatory Bowel Disease

Introduction Mondor's Disease (MD) is a rare condition characterised by thrombophlebitis of the superficial veins of the breast and anterior chest wall. Cases associated with inflammatory bowel disease are rare. Case A 54-year-old male presented to the symptomatic breast clinic with a 6-week history of a painful linear area on the anterolateral aspect of his left chest wall. There was no history of trauma or underlying coagulopathy. He also described increased stool frequency and crampy abdominal pain. On clinical examination, superficial thrombophlebitis with cording was noted along the outer upper quadrant of the chest wall. His past medical history included a previous diagnosis of ulcerative colitis, with no pharmacological treatment. He was subsequently referred to a gastroenterologist and all symptoms resolved following management of his underlying colitis. Discussion This gentleman’s thrombophlebitis followed the course of the thoracoepigastric vein. The occurrence of thromboembolic events has been documented in association with an exacerbation of ulcerative colitis; however, literature describing MD is scarce. The underlying aetiology is reportedly due to the hypercoagulable state identified in ulcerative colitis. There is a lack of consensus on the treatment of MD, however cases have responded well to the management of the precipitating colitis. Low molecular weight heparin can be used if chronicity ensues. Surgical management is not recommended. Conclusions MD is a rare presentation of ulcerative colitis. Clinicians should be aware of underlying aetiologies and a potential hypercoagulable state. Such cases in relation to UC require early diagnosis and treatment of underlying colitis.
