A skin nodule is a raised bump on the skin that's larger than 1 centimeter (cm) but smaller than 2 cm across. It can be solid or filled with fluid (cystic).
Understanding Skin Nodules
The skin, the body's largest organ, along with its associated structures (hair, nails, sweat glands, and oil glands), forms the integumentary system. A key function of this system is protection. Nodules are one type of skin lesion that can indicate a variety of underlying conditions.
Characteristics of Skin Nodules:
- Size: Greater than 1cm, but less than 2cm in diameter.
- Texture: Can be firm and solid, or soft and cystic (fluid-filled).
- Appearance: Can vary widely in color and appearance depending on the cause.
While this definition clarifies what a skin nodule is, it's crucial to remember that diagnosing the cause of a skin nodule requires a medical professional. Many factors contribute to their formation, and self-diagnosis can be inaccurate and potentially harmful.
