Is lipase increased in mumps, malignancy, or ectopic pregnancy?

Lipase is an enzyme primarily associated with the digestion of fats, and its elevation is most commonly linked to pancreatic conditions, most notably acute pancreatitis. In the context of mumps, malignancy, and ectopic pregnancy, the elevation of lipase levels does not typically occur.

Mumps, for instance, is a viral infection that primarily affects the salivary glands and does not cause a significant increase in lipase. Malignancies can lead to various biochemical changes, but again, they do not usually result in elevated lipase levels unless there is also underlying pancreatic involvement, which is not inherent to all cases. Ectopic pregnancy primarily presents with elevated beta-hCG levels, and though it can lead to abdominal pain, it is not characterized by an increase in lipase.

Therefore, recognizing that lipase levels are not elevated in any of these conditions supports the conclusion that the correct answer is that lipase is not increased in mumps, malignancy, or ectopic pregnancy. This understanding reinforces the specific diagnostic roles of various enzymes and markers in differentiating medical conditions.
