A medical condition characterized by hardening and tightening of the skin, especially on the hands and feet.
From Greek 'akron' (extremity) + 'skleros' (hard) + 'derma' (skin), literally meaning 'hardness at the extremities of skin.'
This is a real autoimmune disease where the body attacks its own connective tissue, causing the skin to become thick and rigid—the medical term perfectly describes the 'extreme hardening' that happens first in the fingertips!
