Insights
This case report details a rare ventral tongue epidermoid cyst in a 15-month-old. Surgical removal was successful, with no recurrence observed in this pediatric case.
Area of Science:
- Oral and Maxillofacial Surgery
- Pediatric Dentistry
- Dermatopathology
Background:
- Epidermoid cysts are rare benign tumors, typically found on the skin.
- Ventral tongue location is exceptionally uncommon, especially in pediatric patients.
- Congenital cysts can present diagnostic challenges in infants.
Observation:
- A 15-month-old child presented with a sessile, yellowish lesion on the ventral tongue.
- The lesion, present since birth, measured approximately 0.5 cm.
- Discomfort during mastication due to tongue friction was reported.
Findings:
- Histopathological examination confirmed an epidermoid cyst.
- Key features included a keratinized stratified squamous epithelium-lined cavity.
- Mild inflammation was noted in the surrounding connective tissue.
Implications:
- Highlights the importance of considering rare oral pathologies in pediatric cases.
- Demonstrates successful surgical management of ventral tongue epidermoid cysts.
- Emphasizes the need for thorough histopathological analysis for accurate diagnosis.
Abstract:
The purpose of this article was to present a rare case of epidermoid cyst on the ventral region of the tongue in a 15-month-old child. During clinical examination, a sessile, yellowish lesion measuring approximately 0.5 cm was noticed. The lesion had existed since the child's birth and was causing discomfort due to friction of the tongue against the alveolar ridge during mastication. The chosen treatment was total removal of the lesion. The histopathological findings confirm the diagnosis of an epidermoid cyst, characterized by the presence of: (1) a cyst cavity lined by stratified squamous epithelium with keratinization on the surface; and (2) connective tissue with a mild inflammation. The proposed treatment was considered successful as the case was solved and there was no recurrence.
