Paronychia.

Paronychia is defined most often in terms of inflammation and is classified as congenital, acute-acquired, or chronic-acquired. The cause for acquired paronychia usually is trauma, and middle-aged women are at greatest risk. Chronic paronychia has been associated with numerous occupations where fluids are the common denominator. Mixed infections usually are found in chronic paronychia, including bacteria, fungus, and yeast. Depending upon the type of paronychia and associated organisms, therapy includes footgear considerations, pharmacology measures, and surgical measures.
