Which condition is typically indicated by irritation and swelling around the nail?

Paronychia is a condition characterized by inflammation and swelling around the nail, often associated with pain and redness. It typically occurs when the skin around the nail becomes infected, which can happen due to trauma, irritation from chemicals, or other irritants. Bacteria or fungi can enter through a break in the skin, leading to an infection that results in the swelling and irritation.

Understanding the nature of paronychia is crucial for nail technicians, as it highlights the importance of proper nail care and hygiene. Nail technicians must be aware of this condition to prevent exacerbation and to provide appropriate advice to clients regarding care and treatment.

In contrast, the other conditions listed—plicatured nail, mildew, and leukonychia—do not primarily manifest with swelling or irritation around the nail itself. Plicatured nails involve a bending or folding of the nail plate, mildew is a fungal growth that typically affects the surface, and leukonychia refers to white spots on the nails, often caused by minor trauma or other factors, but does not involve inflammation of the surrounding skin.
