What's a Macule? A circumscribed area of the epidermis or mucosa distinguished by colour different

A freckle is an example of a macule
,What's a Papule? Small, circumscribed lesion usually less than 1 cm
Elevated or protrudes above the surface
Sometimes fused together
What's the main difference between a Macule and One is flat (Macule) and one is raised (Papule)
Papule?
Anything bigger than 1 cm in diameter you want to assess
more
What are Pustules? Circumscribed elevation filled with purulent exudate (pus) resulting from an
infection
Less than 1 cm and may be preceded by a vesicle or papule
Intraorally may be represented as parulis (localized pus) or abscess
Looks like a whitehead
What's a Vesicle? A small, elevated lesion less than 1 cm that contains serous fluid and may contain

The epithelial lining is thin and will eventually rupture causing an ulcer
Can cause a red halo around it
Can cause a bad taste in the mouth after eruption
What's Pedunculated? Attached by a stemlike or stalk-like base like a mushroom
What's Sessile? Describes the base of a lesion that is flat or broad instead of stemlike
Difference between p and s Mushroom base vs flat
, What does a Nodule describe? A palpable solid lesion up to 1 cm in soft tissue
Can occur above, level with, or beneath the skin surface
A solid mass of tissue that has the dimension of depth (extends deep into the

Overlying skin is usually nonfixed and can move easily over the lesion
Usually slow growing and may or may not be painless
