What is the inflammation of the nail matrix that is accompanied by pus?

The inflammation of the nail matrix that is accompanied by pus is best described as onychia. This condition specifically refers to an infection of the structure where the nail grows, which can lead to symptoms such as redness, swelling, and pus production. Onychia often results from bacterial or fungal infections and can cause pain and discomfort in the affected area.

Onychorrhexis, while it describes a condition involving split or brittle nails, does not involve inflammation or pus. Paronychia, while also an infection-related condition, refers specifically to inflammation around the nail rather than the matrix itself. Leukonychia pertains to white spots or discoloration on the nails and is not directly related to inflammation or pus. Understanding these terms helps clarify the specific nature of nail disorders and their appropriate treatments.
