Oral melanotic neuroectodermal tumor of infancy.

Chaudhary S1, Manuja N, Ravishankar CT, Sinha A, Vijayran M, Singh M.Author information 1Department of Pedodontics and Preventive Dentistry, Kothiwal Dental College and Research Centre, Moradabad, Uttar Pradesh, India.AbstractMelanotic neuroectodermal tumor of infancy (MNTI) is an extremely rare, benign neoplasm of neural crest origin composed of relatively primitive pigment-producing cells. It usually affects new born or infants of <1 year of age, generally involving the face or cranium. This case report describes a 4-month-old child with MNTI involving the anterior region of maxilla. A partial maxillectomy was performed on the left side of maxilla and the patient is now under follow-up.

Melanotic neuroectodermal tumor of infancy disseminated by a ventriculoperitoneal shunt and diagnosed from the inguinal sac.

Yoo IH1, Yum SK, Oh SJ, Kim KM, Jeong DC.Author information 1Departments of *Pediatrics †General Surgery, College of Medicine, The Catholic University of Korea, Seoul St. Mary's Hospital, Seocho-gu ‡Department of Pathology, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea.AbstractMelanotic neuroectodermal tumor of infancy (MNTI) is a rare congenital neoplasm that originates from the neural crest cells, which give rise to the melanocytes of the skin and leptomeninges. We report a case of MNTI with neurocutaneous melanosis of a 28-month-old girl. She was born with hydrocephalus and several large congenital giant nevi. There were no findings except for hydrocephalus, after a ventriculoperitoneal (VP) shunt operation performed when she was 6 months old. She was operated on for a growing inguinal mass at 8 months. The specimen from the inguinal sac was positive for HMB45, vimentin, chromogranin, and neuron-specific enolase. Brain magnetic resonance imaging showed an extensive enhancing extra-axial mass with high signal intensity, along the cerebral spinal fluid space. We report a rare case of MNTI, diagnosed from an inguinal hernia sac, with a disseminated clinical manifestation.

Mandibular reconstruction with a fibular osteocutaneous free flap in an 8-month-old girl with a 12-year follow-up.

Faria JC1, Batista BN, Sennes LU, Longo MV, Danila AH, Ferreira MC.Author information 1Department of Plastic Surgery, Hospital das Clinicas, University of Sao Paulo, Brazil.AbstractThe purpose of this article is to describe a case of an 8-month-old girl who was diagnosed with a melanotic neuroectodermal tumor and was submitted to a right hemimandibulectomy and immediate reconstruction with a fibular osteocutaneous free flap. At 12-year follow-up, the longest reported in a patient this young, the transferred bone had grown much like the native mandible, and the patient had adequate mandibular contour and function. No revisions were needed, although orthopedic surgery was performed to correct an ankle valgus deviation on the donor leg. It is the opinion of the authors that microsurgical mandible reconstruction in very young patients is efficient and that the surrounding structures contribute to the remodeling of the bone segment to achieve characteristics similar to those of the native mandible.
