1. How do you differentiate between the different skin disorders?:
2. What are primary and secondary skin lesions?: Primary Skin Lesions
Macule: A macule is a change in the color of the skin. It is flat, and if you were to
close your eyes and run your fingers over the surface of a purely macular lesion,
you could not detect it. It is less than 1 cm in diameter. Some authors use 5 mm for
size criterion. Sometimes "macule" is used for a flat lesion of any size.
Patch: A patch is a macule greater than 1 cm in diameter.
Papule: A papule is a solid raised lesion that has distinct borders and is less than 1
cm in diameter.
Plaque: A plaque is a solid, raised, flat-topped lesion greater than 1 cm in diameter.
It is analogous to the geological formation of a plateau.
Nodule: A nodule is a raised solid lesion and may be in the epidermis, dermis, or
subcutaneous tissue. Generally larger and deeper than a papule.
Tumor: A tumor is a solid mass of the skin or subcutaneous tissue; it is larger than
a nodule.
Vesicle: A vesicle is a raised lesion less than 1 cm in diameter and is filled with clear
fluid.
Bulla: A bulla is a circumscribed fluid filled lesion that is greater than 1 cm in diameter.
Pustule: A pustule is a circumscribed elevated lesion that contains pus.
Wheal: A wheal is an area of elevated edema in the upper epidermis.
Secondary skin lesions are changes that occur as consequences of progression of
the disease, scratching, or infection of the primary lesions.
