It is also known as congenital epulis or Neumann’s tumor. Lesions may be sessile or pedunculated, normally colored or reddish, varying in size from several millimeters to a few centimeters (2), it is typically seen protruding from the neonate’s mouth. Females are affected from 8 to 10 times more frequently than males (2,3),  perhaps indicating a hormonal component in its development. The CGCT oc-curs more frequently in the maxilla (maxillary/mandibular ratio: 3:1), mainly on its anterior portion (2,3). Usually, it is presented as a single lesion, however multiples cases have been reported (3-6).  Surgical excision is advocated as the treatment of choice for CGCT, preferably immediately after detection, since spontaneous regression is rare and large tumors may cause airway obstruction and feeding difficulties (3-11). There are no reports showing CGCT recurrence or malignant transformation (3). The histological picture shows large, round cells with abundant eosinophilic granular cytoplasm, and round or oval lightly basophilic nuclei (3,4,6-10). The histogenesis of this tumor has been investigated, although it remains controversial and inconclusive (3).The aim of this paper is to report a case of CGCT in a 3-day-old girl, presenting the clinical and histological charac-teristics of the lesion and to point out the importance of a multidisciplinary approach to diagnosis and treatment. CASE REPORTA 3-day-old Caucasian girl, born at 40 weeks’ gestation weighing 2.95 kg, was brought by her mother for evaluation of a mass protruding from her mouth, which was causing feeding difficulties, but no airway obstruction.

Congenital epuliswas born by normal vaginal delivery, with uneventful prenatal and perinatal course, and was otherwise healthy. According to her mother she had already been examined by a pediatrician and an obstetrician, who were not able to diagnose the alteration.Intraoral examination revealed a bilobed and pedunculated tumoral mass, with color similar to the adjacent mucosa, arising from the alveolar mucosa on the left maxillary ca-nine region. It was approximately 2 cm in diameter, had a smooth and firm surface and was protruding slightly from the mouth (Figure 1A). Based on the clinical features of the lesion, a CGCT diagnosis was considered and complete surgical removal of the lesion was recommended.Under general anesthesia with nasotracheal intubation, the tumor was completely excised using electrocautery (Figures 1B and 1C). Bleeding was minimal and the infant recovered with no complications. Breast-feeding began three hours after the surgery. The excised material (Figure 1D) was sent for histological examination and the diagnosis was CGCT (Figures 2A and 2B).DISCUSSIONCGCT is usually referred as congenital epulis in the medi-cal literature. However, epulis is a non-specific term used to designate hyperplastic gingival tissue or gingival tumor masses. Since there are cases which are not exclusively related to the gingiva (3,6), it seems that the term CGCT would be more appropriate. It presents a wide range of differential diagnoses, such as granular cell tumor,  fibroma and melanotic neuroectoder-mal tumor of infancy, among others. However, the clinical diagnosis is usually simple due to the typical occurrence in the maxillary alveolar mucosa of newborn girls.Intrauterine images of the tumor may be obtained by ul-trasonography (7,8-10) or even by magnetic resonance (10), mainly in the last weeks of pregnancy.  Although there are studies that affirm successful prenatal diagnosis of CGCT (9,10),  these studies actually obtained images of the tumor mass, suggesting CGCT, but the diagnosis could not be conclusive.

Congenital epulisPrenatal imaging is important in the choice of delivery me-thod, since large tumors may compromise a normal vaginal delivery and a cesarean operation may be necessary (9-11). Also, the identification of a tumor on a fetus may help the intervention planning, and allows the family to prepare psychologically for eventual procedures that will take place in the newborn. Unfortunately, prenatal ultrasound images of the patient were not obtained.The treatment of choice is surgical excision, to be performed as soon as possible (2-11). The use of general anesthesia seems to be the recommended procedure in such cases (3,5,8). There are reports of lesion removal without the use of anesthesia (10), however this kind of procedure is not justified since these surgical interventions are elective. The CGCT removal under local anesthesia is also an alternative (7) when intubation is not possible (4) or in cases of small lesions. There is also the possibility of removal during the delivery, in cases where the lesion was detected during pregnancy (9). This approach may eliminate additional procedures such as anesthesia and intubation, and provides the newborn a free airway and an unobstructed oral cavity immediately after birth.The CGCT diagnosis and management is of interest for the oral and maxillofacial surgeon, the radiologist, the anes-thetist, the otorhinolaryngologist, the pediatrician and the obstetrician-gynecologist. Although several professionals are involved with prenatal and delivery care, sometimes a lesion such as the one reported may cause surprise and concern to the medical team. The interaction between professionals involved with the prenatal care and those involved in the treatment of oral and maxillofacial lesions and syndromes, would certainly optimize the diagnosis and treatment approaches in such cases.
