Myxedema is best described as what?

Explanation:
Myxedema involves non-pitting edema caused by the deposition of mucopolysaccharides (glycosaminoglycans) in the dermis in severe hypothyroidism. This creates a thick, doughy swelling that does not leave an indentation when you press on it. Clinically, it’s often seen around the eyes (periorbital region) and can involve the hands and feet. The key feature is that the edema does not pit with pressure, which distinguishes it from edema due to fluid overload or other causes that are pitting. So, the swelling described as non-pitting edema best fits myxedema.
