What is described by Grey-Turner sign?

The Grey-Turner sign is specifically characterized by bruising or discoloration in the flanks, which indicates retroperitoneal bleeding or hemorrhage. This clinical finding often suggests serious underlying conditions such as acute pancreatitis, abdominal trauma, or ruptured ectopic pregnancy. The presence of such discoloration occurs due to blood tracking along the fascial planes, which can manifest externally as bruising in the flank area. Recognizing this sign is critical for clinicians, as it provides a cue for potential internal bleeding and necessitates further evaluation and management. The other options do not accurately describe the Grey-Turner sign; for example, umbilical bleeding is associated with Cullen's sign, while jaundice and skin rashes signify different clinical conditions that are unrelated to the flank bruising indicative of the Grey-Turner sign.
