Figure 4: Tangential excision of a melanocytic lesion of the nail matrix. (a) Histologic photograph of a tangential excision of a junctional melanocytic nevus of the matrix showing the very superficial lesion. (b) Melanonychialongitudinalis. (c) Visualization of the pigment cell lesion in the matrix. (d) The overlying nail plate is cut away and the nevus is being tangentially removed. (e) The lesion is excised and spread on the scalpel blade to show its thinness. (f) Seven months post-operatively, only a small onycholytic area is seen in the continuation of the former longitudinal melanonychia.
