What term refers to the inflammation of the nail matrix?

The term that refers to the inflammation of the nail matrix is onychitis. Onychitis specifically denotes an inflammatory condition affecting the nail matrix, which can lead to changes in the appearance and health of the nails. The nail matrix is the tissue under the base of the nail from which the nail grows, making it crucial for nail formation and integrity. Inflammation in this area can result from various causes, including infections, trauma, or systemic conditions, ultimately affecting nail growth and structure.

In contrast, alopecia refers to hair loss, folliculitis is the inflammation of hair follicles, and dermatitis is a general term for skin inflammation. These terms pertain to different structures and types of inflammation, making onychitis the correct and relevant choice for inflammation specifically involving the nail matrix.
