Summary
Cervical thymic cysts are rare congenital neck masses. This case highlights a 6-year-old girl diagnosed with a thymic cyst, emphasizing the need for broader differential diagnoses.
Area of Science:
- Pediatric Surgery
- Head and Neck Pathology
- Congenital Abnormalities
Background:
- Cervical thymic cysts are rare, comprising 0.3%-1% of congenital neck masses.
- Often misdiagnosed as branchial cleft cysts or cystic hygromas due to rarity.
Observation:
- A 6-year-old girl presented with a right lateral cervical cystic mass.
- The mass had multiple septae and extended from the mandibular angle along the neck's neurovascular bundle.
Findings:
- Histopathology confirmed the cervical cystic mass to be a thymic cyst.
- This case underscores the importance of considering thymic cysts in pediatric neck masses.
Implications:
- Early and accurate diagnosis of cervical thymic cysts is crucial for appropriate management.
- Broadening the differential diagnosis for pediatric cystic neck masses can improve patient outcomes.
