What is the defining characteristic of a nodule?

1. Soft and flat

2. Solid and less than 1 cm

3. Solid and larger than 1 cm

4. Translucent and blister-like

The correct answer is: Solid and larger than 1 cm

A nodule is defined as a solid, palpable mass that is typically larger than 1 cm in diameter. This characteristic distinguishes it from other types of skin lesions. Nodules are often firm to the touch and can be found in various layers of the skin or subcutaneous tissue. Their size, specifically being greater than 1 cm, is crucial in classification and helps healthcare providers differentiate them from smaller lesions, such as papules, which are less than 1 cm in diameter. The solid nature of nodules signifies that they are composed of tissue rather than fluid, which further aids in their identification in clinical assessments. Recognizing the defining size and solid quality of nodules is essential for accurate diagnosis and appropriate treatment planning in a variety of medical situations.
