In this paper, we report a notable case of onychomadesis after infection of an ingrown nail, in which the external use of basic fibroblast growth factor (bFGF; Trafermin; Fiblast Spray) and antibiotic ointment (Bacitracin-fradiomycin sulfate; Baramycin) led to normal nail regrowth. The gene discussed is FGF2; the disease is infection.
