A macule is a spot. Macules are well defined, flat, have a different color than 
the surrounding tissue and are usually less than 5 mm in diameter.
A patch is a larger spot. This is also a pigmented area that is generally 
greater than 5 mm in diameter.
A plaque is a slightly raised plateau-like area, and can be pigmented or not.
A polyp is a mass of tissue that projects outward from the surface of the 
mucous membranes.
A papule is a small slightly raised area less than 5 mm in diameter. It may be 
pigmented or may be the same color as the surrounding tissue.
A nodule is a lump larger than 5 mm. It may be visible or it may only be 
detectable by palpation.
A vesicle is a small blister less than 5 mm in diameter. It is raised, well 
defined and filled with clear fluid.
A bulla is a vesicle that is larger than 5 mm.
An ulcer is usually a depressed or crater-like area on the mucosa where there 
is a loss of the epithelium, which is the surface layer, and is often yellow 
white in colour.
An erosion is a shallow ulcer where the epithelium may only be partially 
destroyed. These often are red in color.
A petechia is a spot approximately 1 to 2 mm in diameter where blood has leaked 
into the surrounding tissue. These are often found in multiples, and are called 
petechiae.
An ecchymosis is a flat bruised area of haemorrhage larger than 2mm in diameter.
A hematoma is a localized collection of blood outside of a blood vessel that 
may appear raised.
