Acromegaly as a cause of trigger finger

Abstract

We report a trigger finger of the right index finger in a 28-year-old man with acromegaly, in which condition growth hormone increases extracellular volume by stimulating sodium reabsorption in the distal nephron. The increase in extracellular fluid can cause oedematous swelling of the flexor synovium in the digital sheath.
