Differential Diagnosis for Bruising Easily

• Single Most Likely Diagnosis
  • Easy bruising due to Vitamin C deficiency (Scurvy): This condition is characterized by impaired collagen synthesis, leading to fragile blood vessels and easy bruising. It's a common cause of easy bruising, especially in individuals with poor dietary habits.
• Other Likely Diagnoses
  • Vitamin K deficiency: Vitamin K plays a crucial role in blood clotting, and its deficiency can lead to easy bruising.
  • Platelet dysfunction or thrombocytopenia: Conditions affecting platelet count or function can cause easy bruising due to impaired blood clotting.
  • Medication side effects (e.g., anticoagulants, steroids): Certain medications can increase the risk of bruising by affecting blood clotting or blood vessel integrity.
  • Aging skin: As people age, their skin becomes thinner and more prone to bruising.
• Do Not Miss Diagnoses
  • Leukemia or lymphoma: These cancers can cause easy bruising due to bone marrow suppression, leading to thrombocytopenia or platelet dysfunction.
  • Bleeding disorders (e.g., hemophilia, von Willebrand disease): These conditions can cause severe bleeding and bruising due to impaired blood clotting.
  • Liver disease (e.g., cirrhosis): Liver disease can lead to coagulopathy, causing easy bruising and bleeding.
• Rare Diagnoses
  • Ehlers-Danlos syndrome: A genetic disorder characterized by fragile skin, joints, and blood vessels, leading to easy bruising.
  • Pseudoxanthoma elasticum: A rare genetic disorder affecting connective tissue, leading to easy bruising and skin lesions.
  • Amyloidosis: A condition characterized by the deposition of abnormal proteins in tissues, leading to blood vessel fragility and easy bruising.
