Prenatal diagnosis of congenital epulis by three-dimensional ultrasound and magnetic resonance imaging

Congenital granular cell tumor: Report of a case with literature review and differential diagnosis

Congenital granular cell tumor (CGCT) is a rare benign lesion and presents as a fibrous mass arising from the alveolus in the newborn. The prenatal screening of lesions can help in parent counseling, determining the complications, as larger size lesions may interfere with normal delivery and require a cesarean section.

Prenatal Diagnosis of Fetal Oral Masses by Ultrasound Combined With Magnetic Resonance Imaging

OBJECTIVES

To analyze the imaging manifestations of common fetal oral masses by ultrasound combined with magnetic resonance imaging (MRI) and to discuss their differential diagnoses.

METHODS

A retrospective study of 6 fetuses with oral masses was performed at a tertiary referral center. The imaging features of prenatal ultrasonography and MRI in the diagnosis of fetal oral masses were analyzed.

RESULTS

Histopathological examination and/or postpartum ultrasound revealed lymphangioma malformation in 2 fetuses, and mucosal retention cyst, mature teratoma, immature teratoma, and cranial meningocele in 1 fetus, respectively. The teratoma had a characteristic sonographic appearance. In our study, the 4 cases of cystic masses did not have an abnormal vessel architecture. Supplemental MRI revealed a mass effect at the level of the hypopharynx, and in 2 cases with polyhydramnios, the mass obstructed the fetuses' upper airway. Thus, ex-utero intrapartum therapy surgery was performed to secure the newborn's airway.

CONCLUSIONS

Oral fetal tumors represent rare congenital malformations. This study shows that a prenatal diagnosis of oral masses is feasible by ultrasound examination. MRI can further confirm the results of ultrasonography and clearly show the relationship between the mass and the hypopharynx. Ultrasonography combined with MRI could, to a large extent, facilitate early detection and appropriate treatment and improve outcome.

Prenatally diagnosed fetal tumors of the head and neck: a systematic review with antenatal and postnatal outcomes over the past 20 years

AIM

The aim of this study was to review prenatally diagnosed tumors of the head and neck in the fetus and to report antenatal and postnatal outcomes.

METHODS

PubMed/Medline, EMBASE/SCOPUS, Cochrane database and Google Scholar were reviewed over the last 20 years. No language or article type restriction was used.

RESULTS

A total of 1940 record were retrieved. Of the 713 records screened, 566 full-text articles were assessed for eligibility. After 445 articles were excluded for specified reasons, 111 studies met the research criteria and were included for qualitative analysis. Overall, 306 cases of fetal tumors of the head and neck were reviewed. Maternal age was an independent factor. The mean maternal age was 28.2 years and gestational age at prenatal diagnosis was 27.1 weeks. Conventional 2D ultrasound was the standard diagnostic procedure in 27.9% of cases and was implemented in 27.3% of cases by 3D ultrasound and fetal magnetic resonance imaging (MRI). Diagnostic evaluation of intracranial spreading and high-airway obstructions was greatly enhanced by fetal MRI. The more common type of fetal tumor was hemangioma/lymphangioms (42.1%), followed by teratomas (29.7%), tumors of the gingiva (10.1%) and lymphatic venous malformations (9.1%), respectively. Fetal karyotyping was performed only in 9.8% of cases; within fetuses undergoing karyotype, chromosomal abnormalities accounted for 20% of cases. The most common pregnancy complication was polyhydramnios (26.3%). Ex utero intrapartum treatment (EXIT) procedure was performed in 30.1% of cases while surgical excision was used in 22.9% during postnatal life. The survival rate was 35.35%.

CONCLUSION

Fetal tumors of the head and neck are rare congenital malformations. Two-dimensional ultrasound is diagnostic in almost all cases; however, MRI may be an important diagnostic adjunct in targeted cases and help patient selection for immediate intubation at the time of delivery. EXIT procedure and surgical removal of the tumor was associated with good prognosis.

Multiple congenital granular cell epulis: case report and immunohistochemical profile with emphasis on vascularization

Congenital granular cell epulis is a rare benign soft tissue lesion arising from the alveolar ridge in neonates. A rare case of multiple congenital granular cell epulis is reported, alongside a description of its vascular immunohistochemical profile. A female newborn presented with two exophytic pedunculated red nodules located on the alveolar ridge between the future eruption sites of the incisors and canines of the mandible and maxilla. A conservative surgical excision was performed on the second day of life. Histology revealed proliferation of round granular cells containing an abundant eosinophilic cytoplasm with basophilic nuclei, ranging from round to oval in shape. Numerous blood vessels were also seen. Immunohistochemical analysis of the granular cells revealed positivity for CD68, D2-40, Ki67, VEGF, and FGF and negativity for S100, CD34, and CD105. Immunostaining for CD34, CD105, and D2-40 confirmed the presence of a large number of blood and lymphatic vessels. Although rare, an understanding of this lesion is paramount for correct diagnosis and appropriate treatment. In the present report, the immunohistochemical profile confirmed increased vascularization, proving that these lesions are composed of not only new and preexisting blood vessels, but also lymphatic vessels.

Multiple intraoral teratoma in a newborn infant: epignathus

Teratomas originating from the oral cavity are named as epignathus. It is a rare type of teratoma. An 11-day old male newborn was diagnosed with cleft palate and intraoral masses. The mass on the right side was protruding from the mouth. Another one on the left side was extending from the nasopharynx to the oropharynx. The diagnosis of mature teratoma was made based on the histopathological study of surgically excised masses. We desired to report on this case since multiple localized epignatus in a newborn with cleft palate has not been described yet in the literature.

Prenatal sonographic diagnosis of congenital epulis

Congenital epulis is a benign gingival tumor that has rarely been diagnosed prenatally. We report a fetus with congenital epulis diagnosed by ultrasound at 37 weeks' gestation. The mass was diagnosed as originating from the inferior alveolar ridge prenatally. After birth, it was completely removed by simple excision under general anesthesia. Histologic examination revealed a congenital granular cell tumor.

Spontaneous regression of congenital epulis: a case report and review of the literature

Introduction

Congenital epulis is a rare lesion found on the alveolar process of a newborn child, diagnosed soon after birth. The lesion has a site predilection for the anterior maxillary alveolar process and a 9:1 sex predilection for females. Once diagnosed the traditional management of the lesion has been surgical excision under general anesthesia.

Case presentation

The purpose of this case report is to describe spontaneous regression of congenital epulis in a three week old healthy African American female child. She presented with a 1.5 cm bilobed sessile nodular lesion in the region of the right maxillary cuspid. The clinical impression was congenital epulis. Since the lesion was not interfering with feeding and respiration, a conservative approach was taken. The child was followed-up for 18 months, during which the lesion progressively regressed.

Conclusions

Conservative management prevented unnecessary surgery and anesthesia exposure in a neonate.

[Antenatal diagnosis of a congenital granular cell tumor]

INTRODUCTION

Neuman's tumors also called congenital epulis or congenital gingival granulomatous tumors are rare and benign oral cavity tumors. They are usually discovered at birth.

CASE REPORT

A 32 year-old pregnant female patient was followed for gravid diabetes well controlled. A maxillary tumor in the fetus was revealed by the third trimester US. A fetal MRI was prescribed, after discussion with the antenatal diagnostic center, to determine the localization, size, and nature of the tumor. It revealed a 3 cm long tumor with cystic like areas not communicating with the encephalus. A caesarian section was performed 2 weeks before term. A simple tumoral excision was performed at 12 hours of age. Histological analysis confirmed the diagnosis. There was no local recurrence after 6 months of follow-up.

DISCUSSION

A prenatal diagnosis of congenital gingival granulomatous tumor is rare. It is usually made at the third trimester ultrasound scan, rarely with fetal MRI. Nevertheless, prenatal diagnosis allows for a better postnatal management.

Fetal choledochal cyst diagnosed at 22 weeks of gestation by three-dimensional ultrasonography: a case report

Choledochal cyst is a cystic or fusiform dilatation of the extra- or intrahepatic bile duct that has rarely been reported in prenatal cases. Here we report a fetus with choledochal cyst diagnosed prenatally by three-dimensional (3-D) ultrasonography at 22 weeks of gestation. We demonstrated an image of choledochal cyst by using a new ultrasound technique, a 3-D multislice view. After close intrauterine followup, surgery was successfully performed and postoperative course was uneventful.
