Which is an example of a primary lesion?

Primary skin lesions are those lesions which are the direct result of a disease. These include macules, papules, nodules, plaques, vesicles, bullae, pustules, and wheals.

What is considered a secondary lesion?

Secondary lesions are those lesions that are characteristically brought about by modification of the primary lesion either by the individual with the lesion or through the natural evolution of the lesion in the environment.

What is a tertiary lesion?

Tertiary (ie, late) lesions are caused by obliterative small vessel endarteritis, which usually involves the vasa vasorum of the CNS. Factors that determine the development and progression of tertiary disease are not known.

How many types of lesions are there?

There are two types of skin lesions: primary and secondary. Primary skin lesions are changes in color or texture that are generally present at birth or acquired over time, such as a birthmark or an age spot. Secondary skin lesions are a progression of primary skin lesions.

What is tertiary cause of disease?

Answer. Tertiary disease is characterized by the development of autonomous hypersecretion of parathyroid hormone causing hypercalcemia. The etiology is unknown but may be due to monoclonal expansion of parathyroid cells (nodule formation within hyperplastic glands).

What is a primary lesion?

Primary lesions, which are associated with specific causes on previously unaltered skin, occur as initial reactions to the internal or external environment. Vesicles, bullae, and pustules are formed by fluid within skin layers. Nodules, tumors, papules, wheals, and plaques are palpable, elevated, solid masses.

Can brain lesions disappear?

Will MS brain lesions go away? In addition to slowing the growth of lesions, it might be possible to one day heal them. Scientists are working to develop myelin repair strategies, or remyelination therapies, that might help regrow myelin.
