Recurrent Spitz's nevus.
A recurrence of a spindle- and epithelioid-cell nevus following partial removal is described. Clinical and histologic photographs of the original and recurrent lesion and an immunohistochemical stain (S-100) which highlights melanocytic cells and their pattern of growth are included. This nodular recurrence of a Spitz's nevus is contrasted with macular recurrence of ordinary melanocytic nevi that may follow partial removal by shaves. It is presented in order to promote recognition and prevent misdiagnosis of such a recurrence as a malignant melanoma.
