Congenital granular cell tumour of the newborn: A case report and literature review

Clinical and pathological analysis of congenital granular cell tumor

OBJECTIVES

This study aims to explore the clinical and pathological characteristics of congenital granular cell tumors and provide some references for clinical diagnosis, differential diagnosis, and treatment.

METHODS

Nine ca-ses of congenital granular cell tumors who visited the Children's Hospital of Zhejiang University School of Medicine from February 2008 to March 2022 were retrospectively analyzed. Herein, its clinical characteristics, pathological characteristics, treatment, and prognosis were summarized and analyzed.

RESULTS

We found that nine patients were all female, aged 1‑38 days when they saw the doctor. Three of them were attached in maxillary and the other six were attached in mandible. Meanwhile, six tumors were found during the mother's pregnancy at 28-39 weeks and three tumors were found at the baby's birth. One case was excised surgically under local anesthesia, and the other cases were excised surgically under general anesthesia. After 1 month to 12 years of follow-up, patients have no recurrence, however, two cases emerged new teeth from the tumor resection site. Histopathology of all excised lesions was congenital granular cell lesion.

CONCLUSIONS

Congenital granular cell tumor is a benign tumor and the prognosis is good. Therefore, surgical resection of the tumor can be done without extensive resection, and it generally does not relapse. Thus, ultrasonography during pregnancy is an important method for the early detection of congenital granular cell epulis.

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 granular cell tumor

Congenital granular cell tumor (GCT) is a relatively rare intraoral benign tumor, approximately 200 cases of which have been reported in the neonatal period worldwide. The newborn infant may have feeding problems and respiratory difficulties due to airway obstruction. This lesion may be diagnosed by prenatal ultrasonography and simple resection is mostly required. We report a case of an adult type of GCT in a newly born infant, who presented with an intraoral protruding mass with a prenatal diagnosis. This article describes the prenatal course, clinical, and pathological characteristics, and management of the GCT.
