Melanotic Neuroectodermal Tumor of Infancy: A Case Image.

Melanotic neuroectodermal tumor of infancy (MNTI) is a rare benign neoplasm that can be mistaken for malignancies due to its unfamiliarity among clinicians and aggressive clinical appearance. We herein contributed by reporting an additional case of MNTI characterized by an extensive extraoral protrusion in a 2-month-old infant. The lesion involved the anterior maxilla, cheek, and infraorbital region, resulting the displacement of the nose to the contralateral side, and measuring approximately 10 cm in size. Surgical resection of the lesion was performed. After a 6-month follow-up, the patient has shown no evidence of recurrence. The rapid growth and aggressive behavior of MNTI emphasize the importance of an early diagnosis and prompt intervention in order to achieve favorable outcomes.

The epidemiology of mandibular fractures in Caracas, Venezuela: Incidence and its combination patterns.

BACKGROUND/AIM: As reported in the literature by several authors, there is a great variation between countries in terms of etiology and patterns of mandibular fractures. The aim of this study was to determine the incidence of mandibular fractures at the Oral and Maxillofacial Surgery Unit, "Dr. Domingo Luciani" Hospital, Venezuela, during the period January 2010 to March 2013. MATERIALS AND METHODS: A retrospective study was conducted to assess the etiology of trauma, age group, gender, anatomic distribution of injury, and combination patterns by reviewing patients records. RESULTS: There were 334 patients with 522 mandibular fractures averaging 1.56 fractures per patient. Eighty-five percent of the patients were males with an overall male: female ratio of 6.15:1. The highest occurrence of trauma was in the 20-29 years (43.4%) age group. The etiology most frequently observed was motorcycle traffic accidents in 94 patients (28.1%), and the parasymphysis region was the most common location with 144 (27.6%) fractures. Almost half (48.8%) of the injuries were combined mandibular fractures with 29 different combinations, and the most common was a mandibular body fracture + parasymphysis fracture (22.1%). CONCLUSION: Mandibular fracture is a common facial injury with variable incidence and etiology across gender and age range. The findings of this study are similar to other studies and provide important clinical information that will assist in the treatment planning of these types of injuries.
