What indicates the presence of Cullen's sign in a patient?

Cullen's sign refers to the presence of bluish discoloration around the umbilicus, indicative of bleeding in the abdominal cavity. This sign is often associated with conditions that cause hemoperitoneum, such as ectopic pregnancy, pancreatitis, or abdominal trauma. The clinical significance lies in its ability to suggest underlying serious conditions that require further investigation and intervention.

The incorrect options provide other clinical signs or symptoms that, while potentially relevant in an acute abdominal setting, do not specifically indicate Cullen's sign. Flank discoloration may suggest different conditions such as renal hemorrhage but does not pertain to the umbilical area. Cholecystic tenderness is related to gallbladder inflammation, while acute abdominal pain is a general symptom that may accompany various abdominal conditions. Only umbilical discoloration aligns with Cullen's sign, highlighting its diagnostic value in acute care settings.
