Pitting Edema: Clinical Assessment, Causes, and Pathophysiology

The image presented demonstrates a classic clinical sign known as pitting edema, a condition characterized by observable swelling in body tissues due to fluid accumulation. This visual guide highlights the standard diagnostic physical examination technique used by healthcare professionals to distinguish this specific type of fluid retention from other forms of swelling. By applying direct pressure to the affected limb, a clinician can assess the severity and nature of the edema based on the tissue's response.

Adams-Oliver Syndrome (AOS)

Adams-Oliver Syndrome (AOS) is a rare congenital disorder characterized by the combination of aplasia cutis congenita (ACC) and terminal transverse limb defects. Named after the physicians who first described it, Dr. William Adams and Dr. Robert Oliver, this syndrome presents challenges in diagnosis and management due to its variability in clinical presentation and severity.
