Cervical Lymphoepithelial Cyst in a Healthy Adolescent Male: A Rare Benign Entity Mimicking Lymphadenopathy

We report the case of a 17-year-old male presenting with a right-sided cervical swelling evolving over three months. Clinical examination revealed a firm, mobile mass without skin changes or systemic symptoms. Cervical ultrasound suggested a lateral cervical lymphadenopathy in level IIa. No CT or MRI was performed, and the remainder of the ENT evaluation was normal. Surgical excision under general anesthesia was performed, and histopathological analysis confirmed a lymphoepithelial cyst. Follow-up at 2 months, 6 months, and 1 year showed no recurrence. This case highlights the importance of considering benign cystic lesions in the differential diagnosis of cervical masses in young patients, and reinforces the role of surgical excision for both diagnosis and cure.
