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.
