Multiple onychocryptosis following treatment of onychomycosis with oral terbinafine

The authors report an unusual case of multiple onychocryptosis, which developed following treatment of onychomycosis with oral terbinafine. With new growth of the healthy nail plate, the distal aspect of multiple toenails became ingrown with periungual inflammation. This required several minor surgical procedures to alleviate the onychocryptosis. The authors present this case report as a potential complication of oral antifungal therapy.
