An Unusually Thick Scar That Develops in the Lower Layer

Question

An unusually thick scar that develops in the lower layer of the skin is called a:
A) tumor
B) collagen bundle
C) keloid
D) neoplasm

Accepted Answer

A keloid is an abnormal growth of scar tissue that extends beyond the original wound and may continue to grow over time. It is caused by an overproduction of collagen in the skin's lower layer and can result in a thick, raised, and sometimes itchy or painful scar. A tumor, neoplasm, or collagen bundle do not necessarily describe this type of scar formation.
