Premolar Cystic Ameloblastoma in a Child

Area of Science:

• Oral pathology
• Odontogenic neoplasms
• Pediatric dentistry

Background:

• Ameloblastomas are benign odontogenic tumors known for local aggressiveness and potential for significant bone deformity.
• Unicystic ameloblastoma (UA) is a variant presenting clinically and radiographically as a cyst but histologically as ameloblastomatous epithelium.
• UA typically affects young adults and is rare in children under 12, often responding well to conservative management.

Observation:

• A 9-year-old boy presented with a mandibular swelling involving an unerupted first premolar.
• The lesion was clinically misdiagnosed as a periapical inflammatory lesion and radiographically as a dentigerous cyst.
• This case represents an unusual location and presentation of unicystic ameloblastoma in a pediatric patient.

Findings:

• Histopathological examination revealed unicystic ameloblastoma, despite initial misdiagnoses.
• The tumor involved the crown of an unerupted mandibular first premolar, an uncommon site.
• This highlights the diagnostic challenges posed by unicystic ameloblastoma, especially in children.

Implications:

• Accurate histopathological examination of surgical specimens is essential for diagnosing unicystic ameloblastoma.
• Early and correct diagnosis is vital for effective treatment and preventing complications associated with ameloblastomas.
• This case underscores the need for vigilance in pediatric dentistry when encountering lesions that mimic more common conditions.
