Abstract
Three cases of retronychia are reported. Case 1 was a 68-year-old male with retronychia affecting the left great toe, with a 3-year history. Avulsion was performed and revealed an underlying nail plate, which was removed. Case 2 was a 44-year-old female with retronychia affecting the right great toe. She had fallen on an escalator three months previously. Avulsion was performed. Case 3 was a 12-year-old female with retronychia affecting the right great toe, with a 3-week history. Ten days later, the top nail-plate fell off spontaneously, and the underlying nail plate was removed. In all three cases, the lesions (paronychia) did not respond to systemic antibiotics. All three cases were cured by removal of the nail plate. Persistent proximal nail fold inflammation can result from the proximal nail plate in case of stunted nail growth.Skin Research, 10: 505-507, 2011
