Abstract:
This paper reports a case of melanotic neuroectodermal tumor of infancy (MNTI)arising in the maxilla of a 3-month-old male infant.The treatment included surgical excision of the lesion with safe margin,curettage of the maxilla and removal of associated developing tooth bud.Microscopically,it proved to be a dual tumor with small,neuroblastic-like cells and larger epithelial cells.Immunohistochemical staining demonstrated epitheloid cells HMB45(+),EMA(+),CK(+);neuroblast-like cells NSE(+),GFAP(+),S-100(+),but both cells Vim(+),CD45(-),Myogenin(-).The 18-mouth follow-up showed no recurrence or metastasis.The related literature was re-viewed.
