Etymology
The term "Mallet-Guy's sign" is named after Pierre Mallet-Guy, a French surgeon who first described the sign in the mid-20th century. The term combines the surname of the surgeon with the word "sign", which in medical terminology refers to an objective evidence of disease perceptible to the examining physician.
Definition
Mallet-Guy's sign is defined as the presence of a palpable, non-tender mass in the epigastric region, often associated with chronic pancreatitis. The mass is usually due to a pseudocyst or an inflammatory mass in the pancreas.
Clinical Significance

Its presence suggests a chronic or long-standing disease process in the pancreas, often indicating chronic pancreatitis or pancreatic pseudocyst. However, it is not specific and can be seen in other conditions such as pancreatic cancer. Therefore, further diagnostic tests are usually required to confirm the diagnosis.
