Paronychias on toes. Pus (yellow) leaking from paryonychias, or whitlows, on the toes of a 55- year-old woman. A paronychia is an inflamed swelling that develops in the folds of skin at the base of the nails of the feet and hands. It is usually caused by local bacterial infection. However, chronic cases may be caused by secondary infection with the fungus Candida albicans. Treatment is with antibiotic drugs. If an abscess has developed (as here), it may require surgical drainage.
