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. Some-
times "macule" is used for
a flat lesion of any size.
Patch: A patch is a macule
greater than 1 cm in diam-
eter.
Papule: A papule is a sol-
id 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 diam-
eter. It is analogous to the
geological formation of a

plateau.
Nodule: A nodule is a
raised solid lesion and
may be in the epider-
mis, dermis, or subcu-
taneous tissue. Generally
larger and deeper than a
papule.
Tumor: A tumor is a solid
mass of the skin or subcu-
taneous 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 circum-
scribed fluid filled lesion
that is greater than 1 cm in
diameter.
Pustule: A pustule is a
circumscribed elevated le-
sion that contains pus.
Wheal: A wheal is an area
of elevated edema in the
upper epidermis.
