Abstract
- Blue toe syndrome involves blue or purplish toes in the absence of trauma, serious cold exposure, or disorders causing general cyanosis. Clinical presentation can range from a cyanotic toe to a diffuse, multi-organ systemic disease. A 75-year-old man presented with claudication, sudden bilateral painful discoloration of the sole, blue-colored toes, and anuria. Three weeks earlier, he had been diagnosed with acute myocardial infarction and had undergone catheterization for percutaneous coronary intervention. Histopathologic findings showed vascular ectasia with mild perivascular inflammation. Based on patient history, physical examination, and laboratory findings, he was diagnosed with blue toe syndrome. Our patient presented with clinical manifestations, including peripheral cutaneous involvement and acute deterioration of renal function. This case highlights the importance of prompt diagnosis of blue toe syndrome by careful history-taking and physical examination in order to avoid multi-organ systemic disease.
