Lytic pathology refers to which process?

• A. Growth of new bone forming a mass
• B. Breakdown or destruction of tissue
• C. Fusion anomalies
• D. Extra foramina formation

Answer: (B)

Lytic pathology describes the breakdown or destruction of bone tissue. In imaging, this shows up as radiolucent (darker) areas where bone has been resorbed, reflecting loss of structural substance. This contrasts with processes that build new bone or form masses, such as proliferative lesions, or conditions that alter bone shape without destruction like fusion anomalies or the formation of extra openings. So lytic pathology is defined by tissue destruction, not by new bone formation, abnormal fusion, or additional foramina. In clinical terms, causes can include infection, metastatic or primary bone tumors, or trauma, all leading to bone loss rather than new bone growth.
