Differential Diagnosis for Easy Bruising in a 72-year-old Man

Single Most Likely Diagnosis

  • Liver Cirrhosis: The patient's history of non-alcoholic steatohepatitis (NASH), presence of spider angiomas, and a positive fluid wave (indicative of ascites) strongly suggest liver cirrhosis. Cirrhosis can lead to coagulopathy due to decreased production of clotting factors, resulting in easy bruising.

Other Likely Diagnoses

  • Thrombocytopenia: This condition, characterized by a low platelet count, can cause easy bruising. It can be secondary to liver cirrhosis (hypersplenism) or a side effect of medications like atorvastatin.
  • Vitamin K Deficiency: Given the patient's liver disease, there might be an issue with vitamin K absorption, which is necessary for the production of clotting factors. This deficiency could contribute to the easy bruising.
  • Diabetes-related Vascular Changes: Diabetes mellitus can lead to vascular changes that might affect the integrity of blood vessels, potentially increasing the risk of bruising.

Do Not Miss Diagnoses

  • Abdominal Cancer: Although less likely, abdominal cancer (e.g., hepatocellular carcinoma in the context of cirrhosis) could explain some of the patient's symptoms, including ascites and easy bruising due to potential coagulopathy or thrombocytopenia.
  • Sepsis or Infection: Infection can lead to disseminated intravascular coagulation (DIC), a condition characterized by both clotting and bleeding, which could present with easy bruising. Given the patient's underlying conditions, he might be at higher risk for infections.

Rare Diagnoses

  • Amyloidosis: This condition involves the deposition of abnormal proteins (amyloid) in various tissues and can lead to liver disease, among other manifestations. It could potentially explain some of the patient's symptoms but is less common.
  • Hemochromatosis: A genetic disorder leading to excessive iron accumulation in the body, which can cause liver disease and potentially contribute to easy bruising, although it would be less likely given the patient's presentation and known history of NASH.
