Summary
A rare congenital epulis, a benign mandibular mass, was diagnosed in a newborn. Negative S-100 protein staining confirmed the diagnosis, differentiating it from granular cell tumors.
Area of Science:
- Oral pathology
- Pediatric oncology
- Developmental biology
Background:
- Congenital epulis is a rare, benign tumor of the oral cavity that presents at birth.
- It typically arises from the alveolar ridge of the mandible or maxilla.
- Differential diagnosis includes other neonatal oral masses.
Observation:
- A case study of a two-day-old female infant with a mandibular mass is presented.
- Clinical presentation and gross examination revealed a significant lesion.
- Histopathological examination was crucial for diagnosis.
Findings:
- Light microscopy confirmed the diagnosis of congenital epulis.
- The lesion demonstrated negative S-100 protein staining.
- Electron microscopy findings were consistent with congenital epulis and are discussed.
Implications:
- Negative S-100 staining is a key diagnostic feature, distinguishing epulis from granular cell tumors.
- Understanding the histopathological characteristics aids in accurate diagnosis and management.
- Reviewing theories of origin contributes to the knowledge of this rare condition.
