Mazza's sign

Mazza's sign is a clinical indicator used in medicine to help diagnose certain conditions, particularly related to the spleen and abdominal organs. It is observed during a physical examination when a doctor tests for pain or tenderness in the left upper abdomen, where the spleen is located. If the patient experiences pain upon taking a deep breath while the area is palpated, it may suggest an enlarged spleen or other underlying issues. This sign helps healthcare providers assess potential problems, guiding further investigation or treatment.
