Dermatological symptoms manifest themselves in the form of skin lesions, known as eruptions. They can be primary, when the appearance of the lesions is the beginning of the development of the disease and then we are dealing with lesions such as a spot, lump, bump, nodule or pustule. In the case of secondary lesions, they are an implication of the disappearance of the primary lesions and signal the development or disappearance of the disease. Secondary lesions include scale, scab, erosion, abrasion, ulceration, cleft and scar.
