          Abstract

          INTRODUCTION: Melanotic neuroectodermal tumor of infancy (MNTI) is a rare tumor, locally aggressive, usually originated from maxilla and mandible and rarely from the skull. A case of a 4 month-old child presenting a bulging lesion in the midline of the occipitoparietal region with progressive growth is reported. CASE REPORT: The neurologic examination had normal developmental milestones. Computerized tomography scan and magnetic resonance Image showed a highly enhancing tumor, dislocating anteriorly and inferiorly the superior sinuses. In order to prevent excessive bleeding, surgical resection was performed in three stages, with complete removal. CONCLUSION: Based on the absence of tumor recurrence, we believe in a favorable neurological prognosis and in a possible of cure, although the patient was not submitted to any adjuvant treatment.

          O tumor melanótico neuro-ectodérmico da infância é raro, localmente agressivo, originado da maxila ou da mandíbula, raramente originando-se da calota craniana. Relatamos o caso de um menino de 4 meses de idade que apresentava lesão abaulada com crescimento progressivo no couro cabeludo. O exame neurológico apresentava desenvolvimento neuro-psicomotor adequado. A tomografia computadorizada e a ressonância magnética do encéfalo mostravam lesão que impregnava pelo contraste, deslocando anterior e inferiormente o seio sagital superior. Com o objetivo de prevenir o risco do sangramento excessivo, o procedimento foi realizado em três tempos, com remoção completa da lesão. Baseados na ausência de recidiva do tumor, acreditamos no bom prognóstico neurológico e na possibilidade de cura, embora o paciente não tenha sido submetido a nenhum tratamento adjuvante.

            Role of radical surgery for intracranial melanotic neuroectodermal tumor of infancy: case report.

            Melanotic neuroectodermal tumor of infancy (MNTI) is a rare, locally aggressive tumor that arises most commonly from the maxilla or mandible. Infrequently, it originates from the cranial vault, and recent reports have described a favorable outcome after radical surgery. Some lesions are particularly problematic, such as those located along the cranial midline or cranial base and those with significant intracranial extension. Currently, there is no effective adjuvant therapy for MNTI; radiation is precluded by the patients' young age, and chemotherapy trials have not demonstrated long-term efficacy.
