She had a normal previous ultrasound. The primary prenatal impression of this hyperechoic lobular mass from the upper part of the mouth was congenital teratoma, which was measured to be about 42×35×29 mm by ultrasound (figure 1). Ultrasound evaluation with color

Doppler showed a mass protruding from the mouth with a branching pattern of the feeder vessels (figure 2). She had no history of either medication during pregnancy or hereditary diseases or oral masses in other members of her family. Inhibitors,research,lifescience,medical The prenatal ultrasound also revealed mild polyhydramnios (AFI=26) with a normal color. She was pink and vigorous after birth without any signs of respiratory distress or evidence of airway obstruction, even though she had a mass in the oral cavity (figure 3). Clinical examination at the time of admission revealed a pedunculated irregular mass, approximately 60×30×45 Inhibitors,research,lifescience,medical mm in size, attached to the gingiva of the anterior alveolar ridge of the maxilla in the midline of the oral cavity (figure 4). She

had no other abnormalities on physical examination. Paraclinical studies did not reveal any other abnormalities. The serum alfa-fetoprotein level was 17300 ng/mL, which was within normal range for age. Facial CT-scan PR-957 chemical structure demonstrated a soft tissue mass, 62×33 mm in size, extending from the hard palate without any connection to the bone or the Inhibitors,research,lifescience,medical nasal cavity.

Figure 4 Appearance of the baby with the oral mass at the time of admission Inhibitors,research,lifescience,medical in the Intensive Care Unit. After receiving

informed verbal consent from the baby’s parents, pediatric surgical and otolaryngological consultation was done. The intraoral mass was completely resected at second day of life. The baby was Levetiracetam intubated and mechanically ventilated for a day after surgery for proper healing of the oral cavity and further pain management. Breastfeeding was started at 4th day of life, and the baby tolerated it without any problems. The pathologic examination of the removed tissue revealed an ovoid creamy to grayish tumor with an irregular and lobulated smooth surface. It was homogenous cream-gray, with fine lobulation on the cut section. The microscopic examination showed homogenous solid sheets of monomorphic large polygonal cells with eccentric small round nuclei and an eosinophilic granular cytoplasm (figure 5). In the stroma, there was a delicate network of blood vessels.
