What type of lesions are known to change the structure of tissues and organs?

Tertiary lesions refer to complex skin conditions that typically develop as a result of untreated primary and secondary lesions. These can signify changes in underlying tissues and organs due to chronic inflammation or infection. For instance, conditions like psoriasis, lupus, and longstanding eczema may lead to tertiary lesions, which can result in significant alterations in the structure and function of the tissues and organs involved.

This is important in esthetics, as understanding the progression of skin lesions can inform treatment plans and the need for referrals to other healthcare professionals. It highlights the importance of addressing skin conditions early, before they escalate to a point where they could cause deeper structural changes.

Primary lesions are the initial forms of skin changes, such as macules, papules, or vesicles, while secondary lesions arise from changes to primary lesions, like crusts or scales. Allergic lesions are a manifestation of specific immune responses and may not inherently alter tissue structure. Hence, tertiary lesions are distinctive in their capability to induce structural changes in tissues and organs over time.
