Inflammation, pain and swelling may occur episodically, often after exposure to water or a moist environment. Eventually, the nail plates become thickened and discolored, with pronounced transverse ridges.6,8 The cuticles and nail folds may separate from the nail plate, forming a space for various microbes, especially Candida albicans, to invade.8 A wet mount with potassium hydroxide from a scraping may show hyphae, or a culture of the purulent discharge may show hyphae for bacteria and fungal elements. C. albicans may be cultured from 95 percent of cases of chronic paronychia.6 Other pathogens, including atypical mycobacteria, gram-negative rods and gram-negative cocci, have also been implicated in chronic paronychia (Table 1).6 See your doctor Unusual exposures lead to unusual bacteria: eg tropical fish aquarium workers, butchers, farmers.
