乳児の黒色性神経外胚葉性腫瘍の1例

抄録

Melanotic neuroectodermal tumor of infancy (MNTI) is characterized by a rapidly growing mass in the anterior maxilla of infants under the age of one year without predilection to sex. It is either pigmented or non-pigmented in color and either exophytic or endophytic in involving the bone. Any tooth involved in the lesion can be displaced. MNTI is thought to be mesenchymal in origin, probably arising from the neural crest and is also thought to be benign in nature. We report here one case of MNTI and discuss its multicentricity, recurrent tendency and pattern of generization based on the CT findings for our case.
