Rare granular cell tumor affecting a 13-year-old boy.

Area of Science:

• Oral and Maxillofacial Pathology
• Pediatric Oncology
• Radiology

Background:

• Granular cell tumor (GCT) is a rare soft-tissue neoplasm typically affecting adults.
• GCT usually presents as a slow-growing, painless nodule in cutaneous, subcutaneous, or submucosal tissues.

Observation:

• A case report details an incidental finding of a radiolucent mandibular lesion in a young boy during orthodontic evaluation.
• The lesion was diagnosed as a central granular cell tumor, a rare occurrence in children.

Findings:

• Central GCT in pediatric patients is exceptionally rare.
• While generally benign, GCT has a 2% risk of malignancy and potential metastasis.
• The reported case showed no local recurrence after a 1-year follow-up.

Implications:

• This case underscores the necessity of regular dental examinations and specialist referrals.
• Granular cell tumors should be included in the differential diagnosis of pediatric head and neck masses, including intraosseous jaw lesions.
• The possibility of malignancy and atypical presentations of GCT must be considered.
