Final answer:
A flattened elevated lesion with variable shape greater than 1 cm in diameter associated with diabetes is referred to as a plaque.
Step-by-step explanation:
The student is asking about a type of skin lesion associated with diabetes which is described as a flattened elevated lesion with a variable shape that is greater than 1 cm. In medical terminology, this type of lesion is referred to as a plaque. Plaques are elevated, firm, and may be growing in size. Due to the greater than 1 cm diameter, a plaque is not considered a papule, which is smaller in size. Vesicles and bullae are both smaller than plaques and characterized by fluid or pus-filled compositions and are not typically described as firm but rather fluid-filled or suppurative.
