To report a rare case of Invasive Encapsulated Follicular Variant of Papillary Thyroid Carcinoma (IEFVPTC) in a pediatric patient and to review the existing literature on this condition.
Approach:
Surgical Intervention: The patient underwent total endoscopic transaxillary left thyroid lobectomy, chosen for its minimally invasive nature, after preoperative management with methimazole.
Key Findings:
IEFVPTC is recognized as an independent entity in the 2022 WHO classification.
The tumor is rare in children, with this case representing a unique instance.
Ultrasound features can mimic benign nodules, necessitating careful evaluation and consideration of further diagnostic procedures.
Interpretation:
IEFVPTC displays characteristics of both benign and malignant nodules on ultrasound, highlighting the need for vigilance in diagnosis.
Limitations:
The rarity of pediatric cases limits generalizability and understanding of the condition's behavior in this population.
Ultrasound lacks specificity, requiring further diagnostic procedures for confirmation.
Conclusion:
The case highlights the importance of recognizing IEFVPTC in adolescents.
