Journal of the American Academy of Dermatology, 03/06/2013Richert B et al.
The authors sought to assess the shave biopsy technique, which is a new surgical procedure for complete removal of longitudinal melanonychia. They evaluated the quality of the specimen submitted for pathological examination, assessed the postoperative outcome, and ascertained its indication between the other types of matrix biopsies. Shave biopsy is an effective technique for dealing with nail matrix lesions that cause longitudinal melanonychia over 4 mm wide. Recurrence of pigmentation is the main drawback of the procedure.
