What term means any structural change that occurs in a disease?

• A. Lesion
• B. Syndrome
• C. Anomaly
• D. Pathology

Answer: (A)

Lesion is the term for any structural change that occurs in a disease. It describes an abnormal alteration in tissue structure, such as an ulcer, tumor, scar, or area of damaged tissue, that results from disease or injury. A syndrome, by contrast, is a collection of signs and symptoms that tend to occur together to characterize a condition, not a physical change in tissue. An anomaly means a deviation from normal that may or may not be disease-related and isn’t specifically about a disease-caused structural change. Pathology is the study of disease or the disease process itself, not the single structural alteration.
