Cutaneous bone formation may be primary or secondary. If it is primary, there are no preceding cutaneous lesions. If it is secondary, bone forms through metaplasia within a preexisting lesion caused by inflammation, traumaticinjury, and a neoplastic tumor. Paronychia is inflammation of the proximal nail fold and presents as painful periungual erythema, sometimes with associated purulence. Chronic paronychia is most commonly related to mechanical or chemical factors. Here, we report a case of chronic paronychia accompanied by cutaneous ossification in a 33-year-old woman who presented with a 2-year history of recurrent paronychia on the left first finger.
