Subungual schwannoma is quite rare and often causes nail deformity and difficulty in wearing shoes. Complete tumor excision is the treatment of choice, and we advocate that restoring the nail appearance should be considered at the same time. We present the case of 43-year-old man with a big toe subungual schwannoma. We designed a zigzag incision method to excise the tumor and also corrected nail-bed deformity. The patient had a smooth recovery, and the nail plate regrew with a good appearance.
