What describes a nodule?

A discolored flat area
A solid, round or oval elevated lesion more than 1 cm in diameter
A smooth, elevated red area
A small collection of clear fluid

The correct answer is: A solid, round or oval elevated lesion more than 1 cm in diameter

A nodule is characterized as a solid, round, or oval elevated lesion that is larger than 1 cm in diameter. This definition is crucial in dermatology and pathology as it differentiates nodules from other types of skin lesions based on size and composition. Nodules can be formed in various tissues and may indicate different underlying conditions, ranging from benign to more serious diseases. Understanding the specific features of a nodule is important for proper diagnosis and treatment. For instance, differentiating a nodule from other skin conditions such as macules (which are discolored flat areas), papules (typically smaller, elevated lesions), and vesicles (small collections of clear fluid) aids healthcare professionals in determining appropriate further action. Thus, recognizing that nodules are larger, solid masses plays a significant role in clinical evaluations and management.
