What is acropachy?

Acropachy is a rare disorder that may develop in patients with Graves’ disease. It is characterized by expansion of soft tissues that are present in the hands and feet. This expansion leads to swelling of the fingers and toes, giving them a characteristic bulbous appearance identified as clubbing. Similar changes in the appearance of the fingers and toes may be noted in patients who develop severe lung disorders. Swelling that is associated with acropachy is usually painless, though it may progress to the point where it impairs the normal motion of the fingers and toes.
